That's a result and a good price too. Now all you have to do is put it all back to rights!

Yes, right again, plumber been, had a heck of a job as the hole in the soil pipe had been drilled oversize.
But with a mix of fitting he has glued, and clamped a new boss in place, and now two days later still no leaks, so looking good so far.
Total cost £125, not bad for nearly full days work, parts, and a run out to supplier, looks like I found a good guy.

Yes you are right, and that is exactly what I am doing, plumber coming, and if necessary will open up the wall. As you say cannot afford this to go wrong again.

Thanks all

I know you are not keen and I don't know how difficult it would be, but for a 100% guaranteed job I'd remove all the masonry round the pipe so you have good access, after making sure that it isn't holding the house up of course! Then I'd get a plumber in to fix the pipe, I wouldn't think it would be too expensive and then save myself the biggest bill by reinstating the wall myself. The last thing you need is for this to leak again in the future.

The weight on the pipe was caused by some idiot way back, almost filling the hole with cement, this great heavy lump was laying on top of the pipe, but the leak is at the bottom not top.

We have left the soil pipe for the last 16hrs and its still leaking, how long would it need?

No it wont stick if damp same applies with gap cement.

Looks as though the fitting/pipe is running the wrong way, and the way the bracket has snapped suggests theres weight on the pipe pushing it down.

The boss is the abs type, and seems to be weeping from the joint to soil pipe and the boss itself.  This pipe is behind kitchen units, and has soaked the wall to side and showing in the next room, so I really need to get this a good repair, would silicone be good enough for us to not worry about re-starting?

I can see it's very tricky to  pull the joint from the boss and replace it. If it's a rubber boss, solvent weld wont work as it's designed for a particular plastic. And even if it's not, it would be difficult to force solvent weld into it. Maybe your best bet is to let the joint completely dry out, give it a good clean and then use a good quality flexible silicon sealant around it. Let it cure for at least 24 hours and then test it for leaks. As already mentioned, don't seal the area with foam, you may need to gain access to it in the future..

Thanks for that, good tip. I will stuff the area with rockwool or similar, and cut out wall to let in and then use your advice with the plasterboard.

Cheers

I can't help you with the plumbing sorry, but to reinstate afterward I would avoid foam like the plague as it will get everywhere and should you need to get access again it will be an absolute nightmare. I would look to cover it with plasterboard, you may need to make a small wooden frame to support it or maybe just screw a batten to the wall, it's difficult to tell from the picture. Another option to fix the plasterboard is to use bonding, it comes in small bags from BnQ for a few pounds and mixes to a sort of stiffish plaster of Paris. Dab patches on the wall, push the plasterboard onto it, you may need to support the plasterboard until it sets, and it is fixed for life. You can use the same bonding to fill any largeish gaps but get mutifinish plaster to give it a skim afterward.
I hope that helps.

Soil pipe leak/repair
Apr 10th, 2016, 3:26pm
 
This is a slightly two part question, first I have a leak from the base of the boss, were it joins the soil pipe, it is weeping just at the bottom. As you can see by pic, this would be difficult to replace due to position of the brick work, without chopping the whole area out, any ides of how I could repair this, would solvent weld stuff do any good?

The other bit is really for builders , but here goes, how do I replace the brickwork? I was thinking that as its in the cavity wall I could cover the pipes with something then use expanded foam, cut level and maybe plaster over, any ideas?
