Hi all. Has anyone used this stuff before when having a weep on a solvent joint? I got a joint on the soil pipe connecting to the underground drainage pipe which would be a nightmare to rip out?

Not underground as that’s why they only sell it in push fit

Chip it off and use a pushfit coupling

It will work as long as it’s pvc. The reason underground is push fit, is to allow the fitting to take up any ground movement, where a solvent weld would snap.

Rough up the pipe to remove the shine and use gap filler/thicker solvent, not the standard stuff, it’s too thin.

The question is, would you use it on a pipe that is going to be boxed in and tiled? Would it be like using solvent weld and melt the pipe together or does it just set hard and seal the gap.

No I wouldn’t. Cut out and redo.

Get a pushfit coupling for the bottom, short piece of pipe, then a pushfit slip coupling for the top.

I have only used it instead of solvent wend cement for loose fittings,
maybe a rubber glove and force it into the leaking area

I am bemused why it is leaking. It felt like a good fit, I cleaned the pipe thoroughly and used pipe cleaner (usually just use emery) and there is a wee gap at the back. I tested it a few times and it was dry. Today it rained and I saw a damp patch behind it. Rain going down the vent. Bemused

If its just rainwater, can you cut off the fitting and fit this into the orange pipe?

It has a toilet and vent coming off of it. Would need to break out the concrete and cut the pipe further down and then use that fitting. Thanks for the suggestion though.

Could you cut where the grey meets the orange, this would leave the glued part of grey fitting in place but not in the path of water, you wouldnt need to touch the concrete.
Then put that fitting inside and fit a slip socket a little higher?

Just had my 6 Yr old and 4yr old wake up at the same time and throwing up all over their beds. Been cleaning sick for last hour. Poor kids. All tucked back in bed and sleeping. Expecting a few more episodes thos evening.

Do you mean cut the pipe at the end of the grey socket just above the concrete in the picture?

This is my set up..

Looks good. Although if I wanted to use this I would need to change the grey tee as the leak would still be in the pipe that is glued into grey socket. I was wondering, as I can reach my hand into the fitting, could I seal it that way with gap filler as surely there is a leak in there.
