Hello There, Can you please let me know what you think is the best design for installing new drainage pipes for a new kitchen extension -just starting being built from the founds. I've read through the Building Regs (H section) but cannot find detail. My dilemna is ....Should the waste pipe be run outside underfloor to a gully? -to then run to the new inspection chamber or above floor height outside in say a 50mm plastic pipe?
Also thinking about a future washing machine, what is the best way of integrating the waste from the w/m to the same drain line?
