I've noticed a missing piece in the clay pipe at the inspection chamber.
Whilst it's not the biggest piece broken, I don't believe I want my waste water making the clay under my house any wetter.
Any suggestion as how to repair it (I don't really want to replace it)?
- fill with some sand and cement, maybe add some SBR as it will be wet
- line it plastic pipe
- any other ideas
cheers gna
