I am building a kitchen extension and have installed a new inspection chamber/soil pipe etc.
I need to connect the kitchen sink waste into the new drainage system and was going to use an external gulley and trap arrangement feeding into a new 110mm pipe which will run under the new kitchen floor.
Rather that use the gulley and trap, can I keep the waste pipe internal and feed directly into the 110mm pipe or does it have to go external?
