Replacement Soil Pipe

[scallywag]

Folks,

I am shortly going to be replacing my asbestos concrete soil pipe (carefully) and I am comfortable with replacing all the upper elements of the pipe.

I am however a little concerened about what to do with where the pipe enters a concrete base at the side of the house. I have attached a photo below.

How should I connect the PVC pipe and where? Should I chip away at the concrete to see what's underneath? i'm not sure if there would be lots of poured concrete or they have concreted on top of another material? I am reluctant to cut the pipe to fit an adaptor on because its asbestos.

Any thoughts gratefully received.

At the base you are likely to find a few inches of concrete sealing a collar/socket which maybe made of asbestos conc or glaze ware.
There is a good chance you may crack this joint if you investigate then you would gave to remove the entire socket.

An easier way if you are happy with the integrity of the last section of soil pipe is to remove the upright at the elbow and insert the pvc pipe into the socket and seal.

This what I did and advised others to do. I hope it helps.
You can cut it off, so the cut is at a right angle acroos the pipe close to the ground and use the fitting in the thread I have added. Failing that dig it out and use the correct fitting, Sewage is a crap thing to have leaking so try to do it right.

Maybe i'm just a big tart but I wouldn't cut asbestos.

thanks for the comments

I would only cut it as a last resort for obvious resons and if I did I would dress up in a spaceman outfit and keep it very moist and cut by hand! Based on what you have said I may try and take the pipe down to the last curved join that goes into the concrete and use the adptor that you mention to push into that? It would get rid of most of the pipe but minimise the possible damage to underground bits.

I may paint the remaining asbestos pipe in Black paint so that it looks a bit better too.

This has been a whopper of a job. I haven't got to the section in the photo yet because it took me 2 days to remove the top section and pipe going through the wall. One of the sockets was in the wall and fully encased in concrete. The walls are 2 ft thick.

I have now got a hole in the wall (stone and lime mortar) about 1 ft diameter. To secure the new plastic pipe am I ok to put the pipe in position and pack around it with stone and lime mortar? Am i likey to cause it to crack due to any thermal expansion etc?

Still havent decided what to do at the base of the stack but am contemplating some "gentle" chipping at the concrete..

Thanks for any help in advance
