: I live in a 3 storey building. I have 3 bthrooms, that have waste pipes that join in the basement and then connect to the main sewer. There is a vent pipe that runs froom that point up through the house to the roof. I want ot get rid of this pipe by cutting it on the second floor. I need to put in an access panel for a new hot tub I am installing. can I do this? and Should I cap the pipe?.
The vent pipe must remain usable in some way. Either by rerouting the vent to miss the tub on the second floor, or using a mechanical air emitter device on it. the air emitter will require that a proper size vent goes through the roof at some other point. Capping the pipe would not be legal or a smart thing to do.
