Can I use..
I'm in the process of plumbing in on a bathroom remodel and was wondering if what I was planning on doing would work or not..My drain/vent line is in the exact corner of the room. I'd like to hug the wall and install the 3" pvc in a straight line, to do this I would have to use a sweep 90 at the end(horizontally) and then about a 9 or 10" piece of pipe with a sweep 90 vertically for the toilet rough in. Is this ok to do? I'm also wondering about the venting..it's an added in bathroom that had a bathtub, toilet and sink, all hooked to a single vent, is this still ok? I was thinking about using an AAV under the vanity as it's furthest from the vent line.

Hi jamesd86,

A diagram of what exists and what you wish to do with measurement would make it much easier to assist you so that we totally understand what you are trying to do.

As to venting you should have no problem with what you plan as far as the toilet is concerned provided the vent in the corner is the same size vent pipe as the toilet drain line. Any other devices you add to the washroom each require their own vent line to the vent stack and need to attach to the vent stack above where each device's drain connects to the main drain.

Others may have additional suggestions.

Good Luck!

the toilet needs a P trap, not an ell. all drains must have a P trap to prevent backwash of sewer gas into living spaces.


sig: if this is a new economy, how come they still want my old-fashioned money?

Toilets have a trap built into the base, correct?


Popeye only reached for the Spinach can as a last resort...

yes a toilet has a trap built in. they rough in using a elbow. if you use a trap it wont drain...
