The inspector in our area says that they follow Ohio Plumbing code. He says that we need a sealed sump basket with 2″ vent, etc. First question, what is considered the trap, do I need to put a trap in the line somewhere and where should it be. Also, If I want to vent this through its own stack, is it legal to run a 2″ single fixture stack through my roof. Lastly, he says It has to have 4″ coming off of it to be used as a floor drain. Do I need to trap and vent a floor drain in a basement (concrete floor) THis will be basically used for condenstation from a heating/cooling unit? I guess basically, from the sump out to the floor drain, I don’t know what he wants.
