Leaking Soil Stack !

[Monkey Wrench]

I've attached a picture below of a leaking PVC soil stack that needs to be repaired. As can be seen, the leak is coming from the bottom of the stack from what
appears to be a socket ! My first inclination was to cut a small section ( about 3 inches) out of the stack about two feet up from the leak and then pull the
lower part of the stack out in order to see the best way of making the repair.

There is a horizontal branch (for a toilet) about 8 feet up from the ground that goes directly into the house so this should support the upper part of the stack
while the repair is done. However, once the repair is made, a slip coupling would have to be placed over the cut segment of pipe but this would then obviously
not give any support to the upper half of the stack !

Removing the stack completely to make the repair would be a nightmare because of the horizontal branch going back directly into the wall for the WC.

Any advice would be appreciated.

Thank you.

Would be easier as a two man job, one to loosen and lift the top half of the stack, and one to slip in the new section of pipe. You may have to lift the top half of the stack up, pull the tee off the horizontal branch then start from the bottom again.

Thanks for the response TBServices.

The tee is turned back directly to the wall and the branch is cemented straight into the wall. If the top of the stack was lifted up out of the tee there would still be no way of removing
the bottom part of the stack from the tee as the tee is fixed directly into the wall with no movement available.

Thanks again.

Oh I see! Well in that case it seems you're out of luck. Short of taking it all down I can't see another way of doing it right. Maybe someone else will have an idea

Bashing out a bit of concrete and making good on the outside won't be too much of a problem if you need to remove WC branch too. It's all down to how much of a headache it is to get it back to looking ok inside and how round the houses it goes from WC to stack.

Can you put a clip directly below the branch to support it

have you checked its not blocked seem like a lot of leakage i assume the water is coming out of the floor ? before cutting the stack id check for blocage and then cut back round the base see whats there chances are it just needs a cement fillet replacing round the drain

you could cut the stack then use a rubber fitting, don't look much but give more flexibility

Thank you for all the posts.

Yes I could do but there would be sufficient support from the tee branch that goes directly into the wall to not make this necessary.

I must admit I hadn't considered a blockage. The leakage is coming out from around the seal below the end of the socket just above the ground level.

This link doesn't seem to working but, at a guess, is it rubber slip coupling with jubilee clips at each end ?

thats interesting my friend, good

What does this refer too ?


Thanks again.

I would say that if that brown stuff is .... I would lift a manhole to eliminate a blockage first before you cut into . IMHO
