I am remodeling an existing 2nd story bathroom and plan on adding a new tub. The plan is to tie into the existing waste line (3" cast iron - horizontal run) with a neoprene sanitary tee. This tie-in is about 2 feet (down) from the existing toilet tie in. The toilet is connected to the waste line with what looks like a "y" fitting and is vented with the same 3" cast iron pipe about 5 feet on the other side.
Question: If I tie into this waste line in this manner do I need to add a separate vent line and if so where?
[I]"Fearless DIYer".......will try any project ...once!
(see attached "crude" diagram)........sorry guys but I'm no architect. Thanks for the help.
