I’m re-tiling a downstairs cloakroom in my house and need to alter the waste to make boxing it in neater. This is what I’ve come across. The basin waste has a collar thing (not sure what its called) to widen it to 40mm and it is wedged into the soil stack with some electrical tape to make a snug fit.
What is the best way to fit my new waste pipe into the stack? Cheers.
