We've got a strange pipe lurking under the sink. It's closed off with a
valve but - as these things do - it's not exactly been behaving itself as
it should, and it's spent a few years having a little leak whenever it
thinks you're not looking.
Capping it off would be a good idea, but it's not a size I've ever seen in
my limited experience, and I can't find anything near it in the sheds.
It looks like it could be an iron pipe (under the grot and mould and I-
don't-wanna-know-what), and it's BIG. Squeezing into the back of the tiny
cupboard I can just about get ruler and light onto it simultaneously, and
it looks to be about 32-33mm OD (1 1/4"?). The valve on the end has an
exposed male thread, of about 35mm OD (1 3/8"?).
WTF is it?
The kitchen is on the "to-do" list, so the (rotten) floorboards will be up
in that corner and there will be Much Work to strip these strange artefacts
out, but in the meantime, it's a case of not letting it get any worse.
Er, it's an iron water pipe I imagine. Might have once gone to a back boiler
in an iron solid fuel stove? You need to trace it back to where it comes
from. Use an angle grinder to cut it back flush to brickwork (once it is

So off I go on a wander round the likely sources...
Stop 1. Bathroom store with a damn good plumbing trade counter round the
back, staffed by ol' boys who've bin there, dun that. No, the trade
counter's closed down, and the showroom's extended into the space. Soddit.
Stop 2. Jewson. Spotty git hasn't a clue, and half-heartedly tries to sell
me some plastic waste pipe fittings, because they're the only thing that
sort of size he's got. Try Plumb Centre.

Oh bugger!!! Then you could try packing a sheet of loo paper in the
stopcock and fill it with silicone sealant. The paper should hold long
enough to stop the mass of water coming in contact with the curing sealant.
Remember to press the sealant well in to the end of the fitting.
I would suggest Item 6453 - which is a 1" BSP cap. A 1" BSP thread has an OD
of 1.309" - which is about 33mm rather than 35, but the next size up (1 1/4)
has an OD of 1.650" which is nearly 42mm, and probably too big.
