I've got a leak in a drainage pipe where it joins the main vertical soil pipe.
The leak comes whenever the sink or bath is used, because the pipe that carries the waste water towards the soil pipe has come loose. It has a soft rubber insert. I've tried to push it into the other pipe but after a day it came out again. I think it is too perished.
What part do i need to buy?
The other issue is that there is actually no slope at all on that drainage pipe. I guess moving that down is a bigger job as it means a new vertical soil pipe section?
