hi there, Ive been asked to fit a new toilet downstairs. In order to fit the new toilet I’d have to run a new soil pipe to the inspection chamber in the garden about 1.5m away. My question is can I terminate the new waste pipe half way down the chamber or does it have to be at the bottom? I assume it’s the latter because of ‘splashing’ but I’d like some clarification. Any advice would be much appreciated.
