Just wanted to call on the MANY years of experience you all have on this forum. we noticed the ceiling sagging downstairs and plaster cracking. Had the above plumbing checked out in the shower room upstairs and had the shower resealed but it hadn’t fixed, I took the wet plasterboard down until i reached dry it’s and have seen the culprit. we’ve got this above the wet area and it’s leaking every time the bath is run, it seems the leak is coming from inside the pipe rather than seals, it looks like a join but do you esteemed people think i could fix this myself by filling the pipe with seal or tightening something ? please log in to view this image
Try and nip it up, but I'd be very careful. If you overdo it then it could pop. Make sure you know where your stopcock is first. I've had to nip the joints of radiators a few times, just make sure the only bit that moves is the one you want to move. I've had mole grips on the bits I want to keep in place then the spanner on the nut. Think they are 18mm.
Is the water coming up or down? Where is the leak coming from top or bottom? Anyway it’s a doddle of a job so don’t worry to much.
I would have thought if it was leaking from the supply pipe it would leak all the time, not just when the tap is on.
This may be a stupid question but is that a copper pipe? The colour just looks wrong though that may just be down to lighting / camera. Where does that pipe go to? Is that a stop end at the end of the short length of pipe? In effect is that pipe doing nothing? If so you could put a stop end on the Tee and dispose of the cracked short length of pipe. Please note I am not a plumber and any advice offered is probably a load of rubbish.
Dry it off with a paper towel. Run your tap (not sure why it only leaks then mind) and see what joint is leaking. Nip up that joint. If you can turn the water off, I would take that joint off completely and refit using fresh ptfe tape on the threads.
Is the leak coming from the bottom fitting? It looks like a in line valve, where is the water coming from/going to? if you turn your water off and cut the brown pipe off above the valve and then push on a speed fit stop end you should be ok. You haven’t said where the leak is coming from. PS do you not know a plumber, it’s a 5min job.
Think you may have replied to me in error. I was trying establish what is actually there so that a more considerd response could be given. Fair questions though. You need to tag in @TonyG
It looks like dead leg to me. The T piece at the top should have been replaced by a straight connector. Good suggestion about a push fit stop end.
Great advice lads, I’m gonna try my trusty plumber again cos I’d probably balls up any capping malarky yeah it’s a T shape and there’s grey pipe going in and out at the rope of the T
Turn the water off and get a replacement push fit PPE please log in to view this image Really easy to fit. There's a plumming shop (Cheap) in Leechmere industrial estate or B&Q (Expensive)
The pipe coming off looks like a dead leg, I would replace the T. Use one of these and get rid of it altogether would be my advice.
That would leak constantly if it was the isolation valve. It's a quarter turn slot so it's either open slightly or closed. Is the water not tracking down the pipe from above. Either way that pipe shouldn't have been left with an open end.
Definitely don’t think it’s tracking cos it’s dry either side and seems to be a regular drip from the open end. Here’s a better pic please log in to view this image and here’s my cackhanded attempts at confirming there’s no tracking just to be sure please log in to view this image
The section with the copper pipe....is that horizontal from the T, above the T, or below the T. It's hard to tell from the angle of the photos.
What I would do is either: a. Remove the T piece and put a push fit straight connector in its place, and remove the copper section altogether. This would be my first choice. Or b. Remove the stop end on the copper pipe and replace with a push fit stop end. Either option you will need to turn your water off. Both push fit options are 15mm, and will cost about £2 or £3 ish from screwfix or toolstation.
Its a 15mm isolation valve he could just buy a screw on cap and that would seal it. Screwfix part number 55441. Only this time I would put ptfe tape on the threads of the isolation valve.
