Recommendations for a SELF PRIMING (not a submersible!) cellarpump.
 
On Sunday afternoon, when looking in our basement for some (250mL)
15W-40 engine oil to prep up a 1K2W inverter genset I'd bought from our
local Lidl for 99 quid a couple of hours earlier, I discovered the coal
hole section had become somewhat flooded and threatening to flood the
main part of the basement.

A look for the repurposed W/M drain pump on a piece of plywood that I
had used the last time this had happened over quarter of a century back
failed to reveal my makeshift solution to a problem I'd thought I'd well
and truly sorted out just a year or two after cobbling said emergency
cellar pump so I landed up having to resort to bailing it out into a
plastic bucket and hauling each bucket's worth up the steep stone steps
to hand to my XYL to tip out onto the drive.

Needless to say, this was rather exhausting work so I only lowered the
level by an inch or so to provide some respite against the rest of the
basement floor transitioning from being merely damp to becoming actually
submerged.

A few hours later, in the evening, our son finally emerged from his
'sick bed' (he was suffering from a cold of some sort - he didn't look
particularly ill to me but looks, as I well know, can be deceiving) and
offered to help bail out the basement using his "Wickes Wet 'n' Dry" 20L
vacuum cleaner which he'd parked in the drier part of the basement (and
which I hadn't realised was a "wet 'n' dry" cleaner).

Inconveniently, his offer of help, as per usual, was badly timed since I
was nicely settled in front of my PC monitor, watching the last 45
minutes of E4's "Night at The Museum" evening movie by way of
recuperation so I left him to deal with it, or not, on his own. He chose
not to wait so dealt with it on his own. After the movie was finished I
checked out his handiwork. The coal hole level was down to a few inch
deep puddles which needed further attention (the level had risen by a
half inch or so since he'd last vacuumed up the water about half an hour
earlier).

At this point, I needed him to explain the 'wet' usage of his old Wickes
wet 'n' dry cleaner so I could pump the sump dry. The sump consists of a
75mm plastic pipe concreted in place over a gravel filled sump hole at
the far end of the coal hole that I'd put in place over 25 years ago for
just such an eventuality. It had been hidden from his view by a stack of
heavy duty cardboard tray boxes. I managed to pump out another 60 litres
or so which he obligingly dumped each 20L canister's worth onto the
driveway saving me the 3 or 4 trips up our basement stairway.

This morning, the level had actually dropped a half inch from where it
had risen to some 3 hours after that last pumping out session when I
checked it just after midnight. I managed to pump another 30 or so litres
from the sump this time round suggesting that the local water table is
actually returning back to normality after Saturday's "Monsoon
Downpour" (according to my XYL - I never noticed such an event beyond the
day being a bit wet and rainy).

I guess the problem must have been due to abnormally high rainfall after
all rather than a failure in any of our waste water plumbing or roof
drainage so it looks like I really do need to fit an automatic sump pump
to complete the original project that I'd put on hold after completing
the initial speculative provision of a sump pick up point over quarter of
a century ago.

My problem at the moment is the total and utter failure of internet
search engines to find a local supplier of suitable cost effective *self
priming* sump pumps that don't rely on being submersible to function as
such[1]. I want a pump that I can hang onto the wall (or park on a shelf)
that will allow me to poke its inlet hose down the sump standpipe and
route the outlet hose through a hole in the wall onto the driveway to
pump some 20Lpm against a total of 3 to 5 metres maximum head of water
pressure.

I'm willing to shell out up to 100 quid on a neat, all-in-one readymade
solution but considering the effectiveness of that sub 50 quid wet 'n'
dry vacuum cleaner at extracting the water from the sump standpipe, I'm
half entertaining DIYing my own Franken-solution of adding a W/M pump to
the wet 'n' dry vacuum cleaner along with, if necessary, some electronic
switching logic to do the job "for free" (my son was quite willing to
'sacrifice' his old Wickes vacuum cleaner to the current task even if it
meant it 'blowing up' as a result of such 'abuse').

The reason why I'm only "half entertaining" such a DIY project is that
it would be more by way of metaphorically sticking two fingers up at "The
cellar sump pump industry" for being such a bunch of ****s in failing to
provide the obvious no brainer solution to my current problem since it
would absorb a considerable portion of my free time and energy
(basically, I'm a lazy sod).

Since I've reached the end of my tether in 'googling' a solution (source
of a suitable self priming sump pump), I thought I'd prevail upon the
potential source of collective wisdom and experience of this group for
advice.

[1] Although I'm rather loath to dig out my sump standpipe, if needs
must, I would but, of the bunch of potential 'submersible' pumps on page
121 of the Toolstation catalogue, it worries me a little as to what the
description "Not suitable... for permanent installation." implies about
each and every one of these pumps. Do they mean, "Don't chop the 13A plug
off and wire into an FCU." or does it mean they're simply not able to
withstand being sat in a puddle of water indefinitely in between pumping
sessions?

Would it not be cheaper to have some sort of alarm that goes off at a

then use the old vac to pump out.

You could use a boat 'dirty water' pump, they self prime to a meter or
so. E.g.:-

This is just the first one I could find, I bought one a couple of
years ago for just over £50.

A small 12 volt boat bilge pump would go down your existing 75 mm sump
pipe. I guess you could suspend it either above or below the "steady
state" water level. Then have it switched on by a suitable float switch.

Also, there are plenty of cheap "damp" alarms on ebay, I've just bought
one to fit into a friend's condensate drain to give him early audible
warning of a frozen outlet.

Cheaper it would be but I'd still be left with the rather onerous task
of having to haul out buckets of water besides the frequent 20L pumping
sessions with the "Wet 'n' Dry". At my age (the inverter genset and the
"Wet Basement Surprise" just happened to be my 68th birthday gifts - the
former being the 'treat', the latter an unwanted 'gift') I'd be far
happier to shell out a little extra for an alarm sensor with attached
sump pump to prevent miserable wet weather days becoming even more
miserable than they already are.

Incidentally, I've just remembered where in the basement I might have
dossed that makeshift pump - in the underfloor space accessible via a
hatchway into the side of the house not over the half basement area. I
might be able to, after double checking that my son's offer of a free Wet
'n' Dry vac is genuine, create a Franken sump pump by attaching a W/M
pump to the wet 'n' dry vac for free.

AFAICR, the wet 'n' dry vac simply stops sucking once the tub is full.
I'm not sure whether it'll automatically resume sucking when the level
drops since it has to be switched off and the top removed to tip it out
or to use it as a bailing out bucket but it might suffice for me merely
to plumb the W/M pump inlet into the cannister of the vac and leave this
Frankenstein contraption to its own devices.

In this case, a simple water level alarm and my proposed Frankenstein
creation might fit the bill nicely. However, I still prefer a more
permanent automated longer term fix to keeping the basement nice and dry
if I can find a reasonably priced all-in-one solution.

I realise that if my proposed wet 'n' dry vac with plumbed in W/M pump
solution were to work straight off the bat with no further complications
[2], I could easily add a level sensor to create a one off automated
basement pumping solution of my own unique design. :-)

[2] The suction on the W/M pump inlet might mandate the use of a relay to
shut off the vacuum on a 1 minute cyclic basis to allow the W/M pump a 30
or 40 seconds chance of pumping the cannister out to the level of the
driveway outlet some 3 or 4 foot higher.

I'd leave the W/M pump running continuously in this case to save having
to use a one way outflow valve between the cannister and the W/M pump
inlet. Hopefully, between the restriction of the water pump and its
modest in-air suction power, there'll still be enough suction on the sump
pick up hose to draw water into the cannister to cover the water pump
inlet to allow full vacuum to build up and fill the cannister before
shutting off to allow the water pump to empty out the cannister ready for
the next suction cycle.

If I'm really lucky, the vac's built in anti motor flood mechanism might
have enough hysteresis to avoid any such additional relay controlled
cycling. It's all down to a matter of experimentation which takes time
and effort, hence my desire to find a ready made solution.

Yes! Bought one of these for a one off job a few months ago worked very
well and I expect you could use it there you can buy either type of flat
or wire reinforced hose and various diameters for flow rates etc ..

Might need a more sophisticated on off pump switch but i expect you
could modify the fitted one if need be...

PS, I don't know the base area of your sump, but for the lever floats to
work you need quite a big area *and* a way of stopping the pump walking
about on the base. I used a nice stainless steel Grundfos one with a
float in a tube, Grundfos Unilift KP 150-AV-1, which cost about four
times your max. But then I wanted our shower to work without fail daily
for many years, so I think I was justifed. There are probably good
quality ones, possibly plastic, which would be cheaper. My concern,
especially if the sump gets some water in it without actually reaching
the pumping level that gunge would build up and block the float, and I
would advise at least monthly tests with a hose pipe.

This is just the first one I could find, I bought one a couple of years

The problem here is that I'd need to invest in a heavy duty 12v PSU for
a pump with a macerator feature I just don't need. I did try further
searching for self priming bilge pumps but I hit the same 12/24v PSU
problem.

The problem when searching for such tightly specified requirements is
that you tend to land up on manufacturers' websites rather than UK
suppliers' web sites and what few retailer sites you do find, they're all
American (or show dollar prices - same thing).

I've tried searching again and even the submersibles seem to be rather
****, especially those that rely on a cable linked float tilt switch
which require an oversized sump hole to accommodate their range of
movement. It looks more and more like my Franken-solution of vac with W/M
pump will be a better solution for my current setup. :-(

Just replaced a 5 year old Draper dirty water pump (as per Toolstation
pg 121) that has spent 5 years stood in a puddle of water. However the
amount of water this on has pumped out is quite a bit. It took 3 days
non stop pumping to clear the last lot of rain water.

Most, if not all, submersible pumps are self-priming. It is of course
important that they don't switch on until sufficiently submerged, but
that is why it has float switch. I forget to mention in my other posts
about them that it may be important to check the attainable head, this
one is 8m which should be suitable for the OP. Some can cope with
debris up to the size of the water inlet slots, and this may be
important if the sump lining is imperfect.

A small 12 volt boat bilge pump would go down your existing 75 mm sump

That's a no, no afaiac simply on account of the need for a hefty 12v

I've since seen other references about "Not suitable for permanent

that's a surprising way to describe their unsuitability for continuous
pond recirculation duty when you don't want to put prospective sump pump
purchasers off.

I noticed that Screwfix are selling a Titan submersible pump, complete
with the same ridiculous float switch dangling off the end of a mains
flex which requires the diameter of the sump to be double that of the
pump body itself simply to accommodate its range of movement. The
attraction in this case being its low price of 40 quid.

If I *have* to dig out my rather neat sump standpipe, then it might as

pathetically designed automatic float switch operation models. I'm hoping
my experiment with W/M pump and wet 'n' dry vac succeeds. My Franken-
solution looks an ever more elegant option each time I search for a
suitably priced sump pump. A single W/M pump might not be sufficient but
given a free supply, suitable hose and jubilee clips, I'm sure I can
cascade enough of them to do the job. :-)

Yes! Bought one of these for a one off job a few months ago worked very
well and I expect you could use it there you can buy either type of flat

Might need a more sophisticated on off pump switch but i expect you
could modify the fitted one if need be...

Thanks for the link. It's pretty much the same as the 40 quid Titan
submersible currently on offer in Screwfix - same stupid float switch on
a flex idea. If I can't homebrew a better solution with a wet 'n' dry vac
and a seperate pump (possibly 2 or 3 W/M pumps in cascade), then it looks
like I'm going to have to destroy my rather neat sump standpipe setup and
install a cheap Titan pump.

How about this one? Float needs little area and is protected. Perhaps
marginal 5m head.

https://www.anchorpumps.com/grundfos...be-floatswitch

This one is cheaper and has 6.9m head but the float is less well
protected, would need the pump to be fixed by either rigid pipe or
perhaps tied to the wall of sump.

https://www.anchorpumps.com/lowara-d...oatswitch-240v

May well be similar around, try "tube floatswitch" as a search term.

Just replaced a 5 year old Draper dirty water pump (as per Toolstation
pg 121) that has spent 5 years stood in a puddle of water. However the
amount of water this on has pumped out is quite a bit. It took 3 days
non stop pumping to clear the last lot of rain water.


Thanks for that info. I've since come to realise that it was a ****
description against using them as continuously running pond recirculation
pumps. :-(

Some models advise allowing a ten minute rest per hour's worth of run
time so you need to check out their specifications in detail to make sure
you don't fall foul of their warranty's Ts & Cs.

If I do manage to find my emergency pump (I've got an idea where I
dossed it away some 25 years ago), I'll run some tests before adapting it
to the vac. There's no sense in destroying a perfectly good wet 'n' dry
vac if the project is doomed from the start.

If I can't get enough head from the one pump, cascading another W/M pump
or two might solve that problem (assuming I can scavenge them from
scrapped washing machines) or else I might do better to use a dishwasher
pump instead - I think they're a more powerful pump considering that they
provide the necessary energy to rotate the spray arms and jet wash the
dishes.

However, I'm coming to the conclusion that I'm going to land up doing
what everyone else in my position has had to do and dig out a pump sized
sump hole to chuck a cheap 'n' cheerful submersible pump into. :-(

What head will the wet-n-dry suck?

If it is sufficient, you could use it to suck water up to the outside drain
level, do so until the tub is full, turn off the wet-n-dry, open a drain in the
tub, let the tub empty down a suitable hose, close drain, repeat. Before
discussing the best OS for the control system it would be good to know if the

You could use a boat 'dirty water' pump, they self prime to a meter or
so. E.g.:-

https://www.ebay.co.uk/itm/SURGEFLO-...V-Marine-Boat-

Sanitary-Waste/162849834381?hash=item25ea9b458d:g:0mcAAOxySE9Q7-vz

This is just the first one I could find, I bought one a couple of years
ago for just over £50.


The problem here is that I'd need to invest in a heavy duty 12v PSU for
a pump with a macerator feature I just don't need. I did try further
searching for self priming bilge pumps but I hit the same 12/24v PSU
problem.

The 12v output of a (cheap) PC power supply would probably handle it.

We had problems with our cellar flooding when the water table
is high - usually 2 or 3 days after a deluge (it drained off a
plain to the north of us which was riddled with gravel
extraction pits and took its time to reach us!)

The first couple of times, I hired a pump from a tool hire
place but, when the only one they had on one occasion wouldn't
pump below about 18mm, finally bit the bullet and bought a
Hippo.

Self priming, pumps to within 3mm of the floor and can be left
running after the water has all gone without damage. No float
switch so has to be manually operated.

There was a slight dip at one point in the cellar floor which
made it the ideal place to site the pump. The old coal hole
was only a few feet away and the cover had a convenient bar
running across the underside so I put a couple to tie-wraps
together to anchor the hose pipe to (I originally used rope
but after about 15 years it disintegrated!) The mains cable
was hung on a nail just inside the cellar door.

My wife kept vegetables in the cellar so was usually the first
to notice the water rising so the plan of action was to wait
for the water to get near the cellar stairs (slight upward
slope) at which point it was worthwhile running the pump. Open
coal hole and lift out the hose, the cast iron lid ensuring
that it didn't try and get back down the hole again, open
cellar door, remove mains lead and plug into socket in the
hallway.

Observe hose at intervals until flow dropped to a trickle,
then leave a little longer. When finally finished, unplug
pump, replace mains lead on nail a refit coal hole lid.
Finished!

This looks like the pump:

https://www.machinemart.co.uk/p/hipp...ersible-water-
pump/


or: https://tinyurl.com/hippo-pump

although mine didn't come with a 'pump mud pack'.

It cost me about £10 - £15 more than that in B & Q about 35 or
so years ago, so a bargain at today's price when taking
inflation into consideration.


It sat in our cellar for 35 years until our recent move -
never let us down and seems good for another 35 years (but we
no longer have a cellar!)

I did wonder about that. I also wondered where all the water went on the
one I replaced...

So this pump is probably pumping out say 100l/m

https://www.drapertools.com/products...s/25360ins.pdf

as is not pumping as high as 1.5m and it ran for just over 3 days solid.
Now if I am correct that is 432000 litres of water or 432 cu m of water
that went somewhere. That's just short of a fifth of the contents of an
Olympic swimming pool.

drain in the tub, let the tub empty down a suitable hose, close drain,
repeat. Before discussing the best OS for the control system it would be
good to know if the head is sufficient, and if it is possible with the
building constraints....

I did give that option some consideration but the whole project has
become somewhat academic after this afternoon's "Fun 'n' Games" with our
foul water drain and my set of repurposed ex-BT duct rodding kit plus two
purchased sets of drain rodding kits (the problem is in a 16 metre run
down the drive from the main manhole at the top down to the "P Trap" near
the bottom which links into the main sewer line).

My lad had checked out the basement at 9am and it seemed ok then but,
when I checked it out just after high noon (1pm), it was even more
flooded than it had been on the Sunday afternoon! We'd had some rain but
not what I'd have called 'Monsoon' rainfall so there was obviously
something amiss with our drains despite the total absence any foul odours
from the basement. Sure enough, when we lifted the cover off the manhole
at the top of the drive, we saw that water was backed up from the
drainage pipe that runs under the drive to the P trap near the bottom
before it links to the main sewer pipe under the road.

It actually needs nine 2 metre latching duct rodding poles to rod the
drain through to the P trap from the main manhole. The screw fittings on
my makeshift 'drain rods' are smaller and don't match the larger threads
of standard drain rodding attachments so, 25 years or more back, I'd
sacrificed one of the 13 or so rods to solder the female connector into
the brasswork of a standard 4 inch rubber disk drain rod attachment so I
could use my thinner and more than double the length of the cheap, non-
locking drain rodding kit poles to unblock my drains.

Unfortunately, this time round the rubber disk met an immovable
obstruction 2 metres shy of the P trap, hence the decision to make do
with the crap grade drain rodding kits (TWO NEEDED since one wasn't
enough) so we (my son and I) could utilise the spiral claw grab (and the
folding scraper if required - it wasn't required) and with a little more
welly (but not much more since although the rods might have been fatter,
I suspect the plastic tube wall thickness is a lot thinner than the
quality BT stuff I was used to).

The only way I could rod beyond the obstruction was by removing the
rubber disk attachment which allowed another 2 metre rod length's worth
to pass. Unfortunately, my lad couldn't see any sign of it appearing at
the P trap, some ten feet down from the inspection access port. Nor could
he hear any disturbance (the end of the rod hitting the side of the P
trap or gurgling of water passing through the passageway left in the
obstruction after withdrawal of the rodding poles). Quite frankly, it was
a mystery as to where the end of that 16 metres worth of rodding
disappearing into the manhole drainage pipe was going.

My lad had the bright idea of using his Karcher pressure washer to spray
down the inspection access pipe to loosen up the blockage. I let him
despite the fact that he didn't have a 12 foot lance to apply the high
pressure spray to where it mattered, some ten foot or more down. Only
after all of that did we take a break to regroup and consider other means
of clearing the blockage(s).

Alternative tool attachments were considered (and bought by my son
despite my explaining that they wouldn't fit my set of ducting rods)
before we decided that the only way forward was to then buy TWO Drain
Rodding kits (since one was insufficient) so we could actually avail
ourselves of the additional tools without my having to sacrifice yet
another rod end to make up another adapter (and the need for a blow torch
to do the soldering).

So off my son goes, this time to Screwfix since our local Toolstation
was out of stock of drain rodding kits - they'd supplied my XYL with a
size 9 pair of wellies (£8.90) earlier in the day and my sprog with the
drop scraper 100mm and the double worm screw 50mm attachments (another
£4.35) he'd bought against my advice - to purchase the required rodding
kits (£47.98 the pair). Only then were we *finally* tooled up for some
serious drain rodding exercises (hard graft!).

First thing to try was the more promising looking double worm screw 50mm
attachment which we hitched up to both sets of rods. this hit the
obstruction and I screwed in the clockwise direction (being particularly
careful *never* to turn in an anti-clockwise direction - no latch
mechanism like my BT duct rodding kit to save losing rods down the drain!
).

This failed to grab more than a single "Flushable Wipe"[1] from the
'plug' in spite of several attempts. Thus wearied by such fruitlessness,
we turned our attention to the P Trap inspection shaft and here we had
more "Luck" (if you can call retrieving lumps of **** caked "Flushable
Wipes"[1] on the double worm screw 50mm attachment which you had to stand
on to unwind off the double worm screw 50mm attachment before attempting
another 'fishing expedition' 'Lucky').

Eventually, I had amassed a small and stinky collection of turd coated
bundles of "Flushable Wipes"[1] at the end of our drive after about half
an hour's worth of fishing before I decided to have another go with the
duct rods, initially with the disk attachment, then without, both times
without result.

My sprog, who had in the meantime carried on the fishing expedition at
the bottom of the drive, decided to lay off that task and see what I was
up to. He advised me to give it a rest just as I'd decided to withdraw
the unadorned duct rods for the the second time, shortly after which, I
heard a rumbling sound followed a few seconds later by the sight of the
water in the manhole dropping rapidly and finally clearing. By the time
we'd raced down to the P trap, the show was pretty well over.

We'd both had visions of being stuck on this Hopeless Task until
nightfall (it was just turned 6pm by then) so we were both very relieved
and pleased that the blockage(s) had finally submitted to all our hard
work (and expense!). All that was left to do was the tidying up of the
****ty mess on the end of the drive (a heavy duty plastic waste sack took
care of that) and the collection and rinsing off of the various tools and
restoration of the manhole cover and so on and we could finally clean
ourselves up and have a late tea just after 6:30pm.

The sprog finished vacuuming out the remaining water from the basement
so now it's just a matter of time (yet again!) before it dries out.
Hopefully, that's it for the next 25 years or so when, one way or
another, it'll be some other poor sod's problem.

I've decided not to bother with a sump pump after all of that - I've
already 'thrown' some 61 quid at the 'problem' and I don't see any
pressing need for a sump pump now that we know that any basement flooding
is proved beyond doubt to be a blocked foul water drainage issue that
we're now better tooled up to deal with (if dealt with in a timely
fashion that is!).

However, regarding your suggestion that the wet 'n' dry vac might be
able to lift the water all the way onto the driveway, I rather doubt it
could do. Although it managed to suck the water up a 3 foot standpipe
from some 4 foot or so down the pipe which did impress me, I strongly
suspect it won't be able to draw the water much higher than this and it
would have to raise the water another 4 or 5 feet to make your idea
feasible. As I said before, I did briefly consider such an option but it
just seemed so unlikely that it would be able to manage a total lift of
the 10 foot or so required for this task that I immediately discounted it.

[1] "Flushable Wipes" (and I can't stress this strongly enough) *aren't!*
You'd be well advised to totally discount any implication of "Flushable"
on the packaging of such toilet wipes as having any basis in 'Fact' and
treat them as you would "Disposable Nappies" (Diapers for our American
cousins), ie never *ever* to be flushed down any toilet drain.

The 12v output of a (cheap) PC power supply would probably handle it.


Not really unless you're prepared to max out the 3.3 and 5 volt rail
loadings to get more than 11.5 volts out of the 12v rail(s).

In any case, the sump pump requirement, as you will see from my other
post about Tuesday's adventure, has become somewhat academic I'm finally
glad to say. However, thank you (and everyone else) for the various
suggestions.

If nothing else, I'm now all too painfully aware that the cheapest sump
pump option will require a rather deep sump hole to drop a submersible
pump into. Trying to locate a quality self priming pump that doesn't need
total submergence into an oversized sump hole is like trying to buy
rocking horse ****. :-(

I did wonder about that. I also wondered where all the water went on the
one I replaced...

So this pump is probably pumping out say 100l/m

https://www.drapertools.com/products...s/25360ins.pdf

as is not pumping as high as 1.5m and it ran for just over 3 days solid.
Now if I am correct that is 432000 litres of water or 432 cu m of water
that went somewhere. That's just short of a fifth of the contents of an
Olympic swimming pool.


I'm guessing you were trying to lower the local water table. Where were
you pumping it out to? Perhaps its output was contributing to the local
water table via some cunningly hidden route? To misquote, "We're gonna
need a longer hose."

...or does it mean they're simply not able to withstand being sat in a

We had problems with our cellar flooding when the water table is high -
usually 2 or 3 days after a deluge (it drained off a plain to the north
of us which was riddled with gravel extraction pits and took its time to
reach us!)

The first couple of times, I hired a pump from a tool hire place but,
when the only one they had on one occasion wouldn't pump below about
18mm, finally bit the bullet and bought a Hippo.

Self priming, pumps to within 3mm of the floor and can be left running
after the water has all gone without damage. No float switch so has to
be manually operated.

There was a slight dip at one point in the cellar floor which made it
the ideal place to site the pump. The old coal hole was only a few feet
away and the cover had a convenient bar running across the underside so
I put a couple to tie-wraps together to anchor the hose pipe to (I
originally used rope but after about 15 years it disintegrated!) The
mains cable was hung on a nail just inside the cellar door.

My wife kept vegetables in the cellar so was usually the first to notice
the water rising so the plan of action was to wait for the water to get
near the cellar stairs (slight upward slope) at which point it was
worthwhile running the pump. Open coal hole and lift out the hose, the
cast iron lid ensuring that it didn't try and get back down the hole
again, open cellar door, remove mains lead and plug into socket in the
hallway.

Observe hose at intervals until flow dropped to a trickle,
then leave a little longer. When finally finished, unplug pump, replace
mains lead on nail a refit coal hole lid. Finished!

This looks like the pump:

https://www.machinemart.co.uk/p/hipp...ersible-water- pump/


or: https://tinyurl.com/hippo-pump

although mine didn't come with a 'pump mud pack'.

It cost me about £10 - £15 more than that in B & Q about 35 or so years
ago, so a bargain at today's price when taking inflation into
consideration.


It sat in our cellar for 35 years until our recent move -
never let us down and seems good for another 35 years (but we no longer
have a cellar!)


Although the need for a pump has been rendered academic after Tuesday's
drain rodding adventures, I do appreciate your suggestion. What's
particularly appealing about this pump is the fact that, unlike pretty
well all the other pumps I'd been considering, it doesn't need total
immersion to prime itself, just a mere half inch deep puddle of water
suffices in this case!

I'd say that was a major plus point to anyone contemplating a less
onerous means than a bailing and bucket brigade solution to an
occasionally flooding cellar. :-)

Likely true.

I did like the idea of a vac sucking up the water, shutting off, a Rube Goldberg
contraption opening and then closing a drain valve, and the vac slowly huffing
and puffing the water out, like some early condensation steam engine.

I must admit, that was part of the appeal to me when considering the
problem of putting my speculative investment of a standpipe sump drain to
use. :-)

The wet 'n' dry vac had proved it could be done so all that was missing
was some automated way to pump the contents out to where it wasn't likely
to return and haunt me. I did manage to find my repurposed W/M pump (not
mounted on a piece of plywood as I thought I'd done over 25 years ago -
false memory syndrome?).

Hopefully, my memory of it pushing the water up a length of attached
hose going out the back door wasn't false as well. I haven't got round to
testing it since the bearings are stiff and need lubing and freeing up
before I screw it down to some wooden base and find some means of
attaching suitable hose.

I do have a very strong recollection of leaving it running dangerously
close to the water level (W/M pumps simply don't have a self priming
requirement) for hours at a time but I wanted to make damn sure that my
memory of this wasn't a false one before mutilating the plastic cannister
of an otherwise fully functional wet 'n' dry vac.

Since I (with my son's help) have managed to clear the primary cause of
our basement dampness/flooding yesterday by the additional 61 quid's
worth of expense in cheap 'n' nasty drain rodding kits (and a pair of
size 9 wellies for myself in the event of my needing to literally 'wade
in' to another basement flood), the urgency to set up and test my
makeshift pump has totally evaporated. Just the same, I'd like to test
the efficacy of such a makeshift drainage pump sometime soon for future
reference (and, quite frankly, to satisfy my now idle curiosity).

Such a set up could represent a cost effective DIY solution to basic
basement drainage. How many here, in this DIY group, *don't* have a
collection of scrapped washing machine parts to hand? :-)

I must admit, I have flushed a tiny number of them over the past 6
months or so (maybe as much as half a dozen and essentially by accident -
I was always suspicious of their "Flushability" in the first place). The
rest of them, over many years now, I expect would have been due to my XYL
(and possibly our son). I'm not accusing them of creating the drainage
problem, just blaming them :-).

I've advised my XYL that the blockage seemed to consist of these
"Flushable Wipes" and that, from now on, it's better to ignore the
patently false claim implied by this description of "Flushability" and
dispose of them in the waste bin rather than down the toilet pan.

Whilst it's true that they can certainly be flushed down the toilet pan,
it's about as good an idea as flushing used handkerchiefs in that there's
absolutely no guarantee that they won't accumulate in the foul water
drain to induce yet another bout of basement flooding. Basically,
anything more durable than toilet tissue has to be disposed of in the
waste bin.

We can all be thankful at least that our sewerage systems here in the UK
can, unlike those in Greece which seem to have been constructed to a
third world standard, can tolerate such 'toilet tissue abuse' with
ease. :-)

Not really unless you're prepared to max out the 3.3 and 5 volt rail
loadings to get more than 11.5 volts out of the 12v rail(s).

Ay? I use a PC power supply as a general purpose supply and can load
the 12v output quite a bit without any load on the other outputs.


You may be using a PSU with a higher than the usual specification
typical of most PC supplies. Generally, the 12v regulation arises
indirectly from the direct regulation of the 5 and 3.3 volt rails,
relying on tight coupling between the primary and secondary windings of
the compact high frequency stepdown/isolating transformer used in the
classic smpsu based PC supply to hold the 12v rail within its looser
+/-10% tolerance range (10.8 to 13.2 volts).

The consequence of this being that as the loading on the 5 and/or 3.3
volt rails increases, the voltage on the 12v rail rises from an open
circuit low of 11ish volts to a high of 13ish volts. Generally, the
loading on these rails under typical PC use results in less extreme
departures from the 12v rail's nominal voltage than will occur under such
atypical use as supplying all of the output power via just the 12v rail.

Since the internal cooling fan in the PSU itself is powered from the 12v
rail, a hint of this effect can be detected by the quieter than usual
operation when the PSU is being tested on no load by the expedient of
linking the PS wire to a ground wire when it's only connected to the
mains in isolation from any MoBo/peripheral connections (a quick 'n'
dirty check that the PSU is not a DoA unit).

However, the resulting 10.8v on a 20A rated 12v rail powering a 10A
12vdc pump motor load will probably still suffice to run the pump at a
lower, yet still sufficient speed to perform its basic task so such
repurposing of a PC supply may still prove an effective alternative
solution to a more expensive 10A 13.8v smpsu PSU.

I'm not saying a PC PSU can't be used to power 12v devices, simply
stating that you need to be aware of this very common characteristic of
most PC PSUs when used in this way.

Strange. The Hippo I referred to doesn't need to be fully
submerged or anything like it. So long as the water covers the
3mm gap at the bottom it just works!

Probably the closest it has come to being submerged was when
we came back from holiday once and my wife found about 9" of
water at the foot of the cellar stairs. It turned out there
been a burst water main in the road outside and our neighbour
said it had taken five days to persuade the water company to
come and fix it!

Fortunately, the pump was ready for use, as always, so hose
out of the coal hole and plug into mains and wait until it was
safe to go down in the cellar and turn the gas and water back
on again. Fortunately, because of the fridge/freezer, we
didn't turn the electricity off!

Actually, 12.74mm minimum depth to prime it. The 3mm was the minimum
depth before it starts sucking air. Compared to the rest, both excellent
performance parameters! If I was looking to buy a ready made solution,
*that* would be my choice of pump. :-)

Who knows? I just might decide to buy one anyway if only as a 'charm' to
ward off the attentions of Sod on my foul water drainage system. You'd
think ownership of three sets of drain rods (one repurposed from duct
rods) would be enough to thwart Sod's Law but I'd prefer not have my
bluff called and have to *actually* get my hands so filthy yet again.
Adding a pump to the mix of precautions should provide additional
insurance against both Murphy's and Sod's Laws which, after this recent
experience, seems an all too desirable thing.

I'm about to buy a set of 7AH SLAs to recommission my 2KVA basement UPS
to guard against mains outages before Murphy or Sod realises I've been
without UPS protection these past two years or so. You might recall my
reference to the purchase of a 1.2KVA inverter genset from our local,
recently built Lidl store on the Sunday afternoon which my search for
250mL of lube oil had triggered the discovery of the basement flood and
the birth of this thread.

As it happened, I did locate a half full litre bottle of 10W-40 lube
oil, supplied with (or bought for) a previous Aldi sourced 2.8KVA
conventional genset which had proved totally incompatible with my
basement SmartUPS2000 (the bottle has a label tied to it specifying its
intended use).

The lightweight inverter genset specifies 15W-40 lube oil so this half
litre's worth of 10W-40 makes for a slightly over-specced substitute,
leaving me just the task of buying a gallon's worth of unleaded and a set
of batteries for the UPS so I can properly test my hypothesis that only
an inverter genset is free of the over-volting issue that afflicts normal
alternator output gensets when faced with relatively modest amounts of
leading current loads (eg excess capacitive loadings - a mere 4700nF in
the case of the 2.8KVA genset proving sufficient to send its 230v rated
output north of the 275v mark, never mind the 9400nFd's worth built into
the mains input circuit of the SmartUPS2000!).

I'd been hanging on for over a year awaiting Lidl's next batch of 1.2KVA
(pk) inverter gensets to arrive in their stores when I spotted,
completely out of the blue, a half pallet's worth (4 or 5) at the bargain
price of 99 quid rather than at their more usual 129 quid price point.
That low price was an unexpected bonus, matching the price paid by
another 'jammy' poster to this news group nearly two years back who'd
discovered his 99 quid bargain hidden underneath a pile of clothing in
the "Reduced To Clear" bin in another Lidl store (the lucky git!).
Suffice to say, that was the very first item placed into the XYL's
shopping trolly that Sunday afternoon. :-)

At the time when I read that lucky git's posting, my thought was, "Yeah,
at that price, even though it's way under-powered for my needs, it's
still worth a punt just to prove that the 600 quid, cheapest model of the
type that I've been able to track down, 3KVA rated inverter genset would
solve the UPS issues that I've suffered with that cheap 180 quid 2.8KVA
conventional genset I'd bought from Aldi a year or three earlier.".

I've since rethought my requirements and reached the startling
conclusion that a 1KVA continuous (1.2KVA peak) rated inverter genset
should just about suffice to keep the lights on (now all LEDs), along
with the central heating pump, master TV set and my desktop PC and NAS
box and network kit as well as the fridge and, with careful management,
even the chest freezer!

It did help somewhat that the SmartUPS2000 had proved itself capable of
supporting the 25 to 30 amp degaussing surge of a 19 inch colour monitor
without tripping out when on battery power but I suspect the toughest
startup load transient of a chest freezer compressor still pales into
insignificance compared to the degaussing surge loading of that now long
since disposed of 19 inch CRT colour monitor.

The genset may be able to handle such a surge loading without the backup
of the SmartUPS in any case. The trick here is to manually control the
freezer compressor run times by switching to "Fast Freeze" so that it can
be left switched off for 18 or more hour periods of the day and only
allowing restarts during no to light loaded periods of the day. The
fridge presents a similar if less harsh startup surge loading regime but
shouldn't prove too problematical. In any case, the UPS should take care
of any "Oops!" moments if the fridge picks a bad time to stress the
genset.

Obviously, a 2.5 to 3 KVA (continuous) rated inverter genset would be a
more optimal solution to protracted power outages but electric lighting
and TV entertainment with a freezer full of food, along with a fridge's
worth of chilled comestibles, is a far better option than making do
without central heating, TV entertainment or internet access and having
to rely upon candles or Tilley lamps to keep the house lit even when the
use of a more marginally sized 1KVA(continuous) genset demands fairly
tight hands on management.

BTW, if anyone is considering such an emergency power setup to keep the
normal house lights burning (along with a small selection of 'critical
appliances'), any changeover switch or relay contacts will need to be
rated for a minimum of twice the mains supply voltage upper limit of
265vrms (530vrms - preferably 600vac or higher).

With plug in appliances, this requirement can be neatly sidestepped by
manually unplugging them from their normal ring main sockets and plugging
them into a seperate emergency genset power socket (typically via a mains
extension lead). It's only when you want to run the existing lighting
circuits from the genset, rather than rig up an entirely seperate
lighting circuit, that you need to specify 600vac switch/relay contacts.
