In response to Re: vent lines.
The important thing is that the lavatory (sink) drain cannot drop down before it reaches the vent pipe.
: I am putting in a powder room bathroom and i have some questions.
: 1. The sink will have a 1 1/2" waste line w/ a 4" vent 18"+/- down stream.
: 2. toilet is located 7' from existing vent line.

: Question: do I need to vent sink w/ vent so near, and do I need a vent for the toilet?
