I am renovating my bathroom. The old bathtub drain is (2). I want to move that drain to (1) for a better location for the shower. The question is: what do I have to do?
The old drain has a P trap and then goes directly into that vertical pipe below the slab. I assume this is a wet drain.
The distance from (2-old drain) to (3-vertical pipe) is about 30 inches. The distance from (1-new drain) to (3-vertical pipe) is about 72 inches.
--Can I just connect the new drain to the old drain pipe (assuming proper slope) and have it be ok? Or is the 6 foot distance too far to use the wet vent?
--I'm assuming that I can use that pipe for drainage, no problem. It's the venting that I'm worried about. If I can't just connect the pipes because 6 feet is too long, how else do I vent this?
This is a load bearing wall, I believe. I only mention that because that limits the defects I can create in the studs.
