I've been looking around for a cheap pump that can I can use to move
water around from various 55-gallon rain-water collection drums. I'd
also like the pump to be able to develop some decent pressure to push
water to at least a single sprinkler head.

Spending more than $100 sort-of defeats the purpose of collecting rain
water to begin with, so something like a convertable jet-pump (minimum
$250 around here) is out of the question.

There are some 1/6 to 1/3 hp sump pumps that I can get for $50 to $75,
but I'd have to modify them so I can attach an inlet hose (most of my
drums are sealed with only a 2" opening at the top so the sump-pump
can't be dropped down into the drum).

So - can a sump pump be modified to be able to draw water from an inlet
line - or will priming it be a bitch? And can then generate enough
pressure (what - 20 to 40 psi?) to drive water through a 50-foot garden
hose and a single sprinker head?

I'd could answer your question but I won't since I'm one of those GG
morons.

I just couldn't resist..............

Here's your answers

"Probably not but maybe"...... depending on pump design.
It would be easy for me but YMMV.
"Yes, probably" but the exact answer depends on the characteristics of
the pump and the flow & pressure requirements of the sprinkler.

In general, sump pumps are volume not pressure pumps. An impulse
sprinkler needs 30 psi or more to operate reliably IME. You could
check the pump ratings which will be in the literture wth the pump.

There are many "shallow well" pumps out there that are available
cheap..d

Your design would call for the water to be gravity drained into a
bucket, tank etc and pumped from there.

Sump pumps are designed for neither. A self priming sprinkler pump would be a
better bet. Bottom of the drum outlets would help with the priming issue.

I was looking at the Harbor Freight shallow well pump for a similar use.
When on sale, it is about $80. I was thinking of getting it to pump
water from my running stream to connect to the house for water when
there is a power failure using my generator. My regular water comes
from a community well which is not close enough to power from my house.
The only reason I haven't done it is because it is not a priority as
we rarely have long power outages. Actually during the one 10 hour
outage (tree fell on the line feeding my area), I never ran out of
water. As there are only 3 houses on that well, with pretty low usage,
the piping going up to the well, maybe 75 feet up the mountain, acted
like a storage tank.

I second the suggestion to use a passive system. I use a length of
soaker hose to slowly drain the tank. You may need to poke a little
hole in the hose at various watering points since there isn't any real
pressure, but it works well and is the green thing to do.

Molly Brown wrote:

No, because a sprinkler head I can move around beats the time and effort
and perceived coverage efficiency and water-delivery-rate of a hose with
a bunch of holes punched through it.

Also, I need to move the rain water from the point where it's collected
to the area where I want to keep the 1/2 dozen or so drums. Need a pump
to do that because it's up hill.

Welcome back.

Here's your answers

"Probably not but maybe"...... depending on pump design.

How many different designs are there for your typical fractional-hp sump
pump?

It would be easy for me but YMMV.

Easy - to do what? *Add a hose connection to the inlet of a sump pump?

"Yes, probably" but the exact answer depends on the characteristics
of the pump and the flow & pressure requirements of the sprinkler.

So in other words, you don't know what static pressure a $50 or $75 1/3
to 1/6 hp sump pump can generate, and you've never modified a sump pump
to give it a hose inlet so you don't know how much head they could
draw.........

HG-

Your assumed answers are incorrect......

I can & did answer your questions...... unfortunately, for you, more
than a bit cryptically

Try the following:
learn to read a pump curve
research the concept of NPSH.
stop using pump terminology you don't understand

The material in that PDF file does not give any real-world performance
examples or numbers regarding sump pumps.

Simple solution:

Obtain 5 gallon bucket and approximately 6-8 feet of garden hose.
Drop sump pump into bucket.
Position bucket next to collection barrel.
Insert short garden hose into collection barrel.
Suck on said hose to create siphon.
Allow siphon to fill 5 gallon bucket.
Allow sump pump to empty 5 gallon bucket.

Yes, one can.

Most of the others cannot.

Stop pretending you can think, and actually do it.

Hint #1:
What are the flow & pressure requirements of your chosen sprinkler
head?

Hint #2:
Flow & pressure capacity of potential pump?
Read the pump curve.

Hint #3:
Pressure drop characteristics of garden hose?

That should be more than enough for you to figure this out.
Plus, just think about the feeling of accomplishment when you do!

If you have an air compressor attach it to your water storage drums or rain barrels with a
tube that goes to the bottom of the rain barrel and a air fitting that connects to your air compresser hose . The air compressor will give you the pressure you need to drive the water out of the barrel and up and out the water tube hanging in the barrel connected to the sprinkler head .
Might need a compressor with a air storage tank ?
Again as with water pumps it depends on the capacity of the air pump .
And the air pump could be used for lots of other projects.

I think what you are asking is what is the max pressure that a given sump
pump can generate. If they don't have it in the pump spec, they should
have the max lift height of the pump. One foot of lift is .43 PSI.
The actual pressure in any application depends on the lift, pipe size,
length, etc.

Basically, a sump pump is unlikely to produce enough pressure for a
sprinkler, which typically need a minimum of 20 psi to work properly,
and often twice that.

Hi! This is a bit of a long shot as I know this thread is old, but I was just wondering if you ever figured out a solution for your rain barrel?

I'm in a similar situation... My rain barrel just drains so SLOWLY. I'd like to hook up a proper hose and nozzle, or even a sprinkler...

Did a sump pump work?

I was thinking of cutting open the lid of mine to make it removable, that way I could completely submerged the pump.

I'd love to hear from you! Thanks!

IDK what well pumps you're looking at or where you get your prices,
but a basic well pump can be had for $125 too. What well pump costs $1500?
Even typical submersible costs less than half that. For something like
this, can probably find low cost or used ones on Ebay too.

Probably the cost of the snubber to fit a barrel...

Seems like overkill to me for the purpose, though, too...guess depends
on just how big the rain barrel really is--just a 55-gal drum wouldn't
go all that far or last long.

A 4" 1/2hp on Amazon for $110+free shipping is still 25 gpm nominal
barring the outflow restriction to a 5/8" garden hose or the like...of
course it's max 125-ft/85-ft rated head and with no lifting loss would
be near 50 psi exit pressure one would guess (presuming numbers aren't
grossly overstated).

For half that, could go with a general submersible plastic utility pump
(Superior Pump 91250) that's 25-ft head/30 gpm that's probably a lot
more suitable to purpose.

Even typical submersible costs less than half that. For something like
this, can probably find low cost or used ones on Ebay too.

Probably the cost of the snubber to fit a barrel...

Seems like overkill to me for the purpose, though, too...guess depends
on just how big the rain barrel really is--just a 55-gal drum wouldn't
go all that far or last long.

That's a very good point. Especially since they mentioned a sprinkler.
One head is typically 2 GPM. If you have 3, the barrel will last less
than 10 mins. And if you're trying to water turf, that amount is pointless.
Most of that will just get it wet, barely start to penetrate, most will be lost
to evaporation as it dries out, unless you can continue with another water
source. If you do the math, to put down 0.5" of water over any reasonable
area takes a lot of water. It's thousands of gallons to water my front lawn.










A 4" 1/2hp on Amazon for $110+free shipping is still 25 gpm nominal
barring the outflow restriction to a 5/8" garden hose or the like...of
course it's max 125-ft/85-ft rated head and with no lifting loss would
be near 50 psi exit pressure one would guess (presuming numbers aren't
grossly overstated).

For half that, could go with a general submersible plastic utility pump
(Superior Pump 91250) that's 25-ft head/30 gpm that's probably a lot
more suitable to purpose.

Indeed...well let's see

G2CF=@(g) 0.133681*g; % gal to cu-ft
A=20*20; G=55; % 20x20 sprinkler area, 55 gal drum
fnDPTH=@(h) A*12*h-G2CF(G); % vol over A of h less total volume G gal
d=fzero(fnDPTH,0.1) % how much can put on area A with 55 gal?
d =
0.0015


So, assuming a 20x20 sprinkler area, 55 gal would be about 1.5
thousandths of an inch...

(Yes, it's solvable by simple straight algebra, but since we're
overthinking a problem here anyway, let's keep up the tradition...)

To beat the horse entirely to death...

H=0.5; % let's put down 1/2" over same A
fnGAL=@(g) A*12*H-G2CF(g); % solve for g, not h
G=round(fzero(fnGAL,1000),-1)
G =
17950


or almost 18,000 gal.

Of course, when one considers real irrigation of putting down over a
growing season an acre-foot over a 127A circle it sorta' pales...

Cover the yard with rain barrels and won't need to water...

A standard 55 gal drum is 22.5" diam so the assumed area A of 20x20 ft
sq would hold

20*12/22.5
ans =
10.6667

on a side or only roughly one-third as many as needed.

OK, I'm done...

I was thinking of cutting open the lid of mine to make it removable, that way I could completely submerged the pump.

I'd love to hear from you! Thanks!

Since you want pressure to run a sprinkler, why are you looking at sump pumps
instead of a water pump used for a well?



Probably cost. Sump pumps can be had for $125. Well pumps $1500 and up

OK, I see some shallow well pumps cheap. Grundfos deep well high
capacity are easily $1500

I use a "pony pump" tp punp water from my 4 rain barrels.300gph at
about 5psi

Or a sprinkler pump perhaps.

What about cutting a hole in the side toward the bottom? You
could use a bulkhead
tank fitting and a shutoff valve. Then even a drill powered pump would
work if you want to generate some pressure. Use one of those sprinkler
hoses. There are spray nozzles for center pivots that don't require
much pressure to work. Those 55 gallons won't go far anyhow.
This is a bulkhead tank fitting:

Just how big is this rain barrel? A barrel in my world is
usually 55 gallons.
It's about waist high and maybe a couple feet in diameter. The
definition gets
a little loose after that. The words tank and barrel are sometimes used
interchangeably.
