Hello,

In the pipe freezing thread I was asking about changing some kitchen
sink taps. I'm afraid I have not changed the taps because all the nuts
are scaled over. I presume the tap connectors have weeped over the
years (fibre washer worn?) and the water has evaporated leaving the
scale behind. As you know, there's never much room to manouvre under a
sink at the best of times and even using one of those special spanners
I couldn't shift the nuts.

If I could get the tap connectors undone, I think I will have the same
problem with the tap back nuts. The hot water one in particular was
buried under calcium!

Other than cutting the pipes and ripping the sink out and replacing
the sink and taps together, what's the best way to take out the taps?

Can the scale be dissolved off with an acid or vinegar? Would a blow
torch help loosen the nuts?

Thanks in advance,
Stephen.

Pretty standard experience for me unforetunately.

What kind of 'special spanner' did you use? There are various typs & some
are better than others.

If you can cut the supply pipes to give a 'straight line' to the tap
connectors a box spanner will work, and will also sort the back nuts. If
the back nuts are plastic they are likely to be brittle & a good bashing
will break them.

WD40 helps, as does a little percussive maintenance.

Correct spanner if often the key, which is why my plumbing bag is so piggin
heavy.

You forgot to say what weight of percussive maintenance to use :-)

I used something like this:

You are now going to tell me I should have used this:

aren't you

The box spanner idea sounds good because they surround the whole nut
so will not slip off, like the wrenches do. It does mean cutting the
pipe though, which is a sort of point of no return.

That's what I was thinking, so it's good to know I was heading in the
right direction. That said, the underside of the sink looks a little
rusty so I worry too much force might rip the sink as well as the taps
out!

Errm. Afraid so :-) The first one is a useful as a back pocket in a sock.

At least I haven't suggested

which is what I use, worth every penny.

Easy to repair or replace using flexible tap connectors.

Helps if you have an assistant to (a) hold the tap still with mole grips or
stiltsons or (b) turn the tap while you hold the nut still with the basin
wrench.

It will come off! Think positive!

I knew there was one that was liked by the group and one that wasn't
but I couldn't remember which was which. In defence of the first one,
I have used it to remove my old bath and two basins, and refit all of
their replacements. I guess they work when the fittings are clean and
accessible.

I think the problem I have had is that I am now working on a sink,
where the joints are more out of reach.

You mentioned box spanners before and I was going to say it is a shame
they do not make very long box spanners that would reach from the tap
connectors down below the sink basin where you could easily fit a
tommy bar. I'm not sure there would be much room to turn the bar
squashed between the sink bowl and the wall.

I guess the second tool has some good features: it seems to have a
long handle that would drop beneath the sink bowl where it could be
turned more easily. I hear you can attach a wrench from a socket set
to some of them for extra leverage.

I am puzzled by the latest offering from Monument:

http://www.toolstation.com/shop/Hand...0/sd210/p63844

It has two ends. What is the second used for? At first I thought there
was one end for 15mm and the other for 22mm but I thought the "claw"
was one size fits all? Then I notice the second end is in a different
plane. Is one end for vertical use and the other end for horizontal?
Aren't 99% of tap connectors vertical?

At least I haven't suggested
http://www.screwfix.com/search.do;js...ch=jaw+dropper
which is what I use, worth every penny.

I looked at this and your review but I am unsure what it does. Why do
they come as a pair? Is there a 15mm and 22mm version? Am I right tot
think that they tighten the tap back nut and tap connector nut at
once? What's the point of that? To prevent one coming undone whilst
you tighten the other?

Thanks.

There isn't :-) I often use s stubby screwdriver instead.

You can get them with short & long handles & even telescopic.

I think the photo is confusing. The end piece swaps from side to side
depending on weather you are doing up or undoing. I think this has two jaws
to reduce the size when using 15mm.

Yes, one for basins, one for baths.

The second jaw isn't a hexagon, its just circular. To undo a pipe connector
they are positioned together & it acts as a guide to locate the first
hexagonal jaw on the nut. When undoing back nuts its slid down out of the
way.

In the last week or so I've freed off a corroded stop tap by heating
up a lemon in the microwave and sticking it on the exposed spindle of
the stop tap (the crossbar had loosened and come off) and repeating a
few times, then spraying the whole valve with 3 in 1 oil, then WD -40,
and then with aerosol white spray grease, and leaving it all to soak
in, before refitting the crossbar and having another go which was
successful this time.

Sorry, I forgot to ask is it ok to use oil on these fittings? It is
what I was thinking of doing myself but considering it is tap water,
is there a danger of the oil getting into the water? Is it just a case
of not applying too much to begin with and wiping the excess of the
pipe as soon as you open the joint?

Well if it's just a case of freeing off a siezed stop tap the water
can't get contaminated until the solvents / oils have got through and
penetrated the gland whereupon they will meet the water which will be
under high pressure, and hence tending to come out. rather than admit
any contaminating fluids in.
