Chasing in soil pipe to internal wall

[Philip Ingles]

I live in a late Victorian terraced house in London. There is boxed in soil pipe on the landing which comes from an ensuite bathroom. A builder has told me he can chase this into the internal wall - between us and our neighbours.

He said (and I believe) the wall the be 9" thick and the soil pipe is 4" diameter. He told me this could be done using lintels over the recess for the pipe but I am unsure. I would have thought that, as a supporting wall, it is unsafe to make a 3 metre long channel in it.

Can anyone offer any advice please? Is this possible? Is it a good/bad idea? Would I need building control/regulations? Thank you.

bad idea.

very bad.

Bad idea but possible.
Definately need blg regs
Def need to comply with Party Wall Act.

The chance of anybody doing this without causing at least minor plasterwork damage to next door is virtually nill.

Thanks for the posts - seems it is a bad idea as I suspected.

I did think about Saniflow but I have suggested it to a few people as a possible solution and they have all warned againt them saying they are nothing but trouble....

Saniflo are ok and reliable untill something solid is flushed - which will block them.

Even the model they advertize as being able to handle sanitary towels block on occasion.
