    Hello again,

    I have a 1 1/2" riser roughed in in my basement for a bathroom sink. I want to connect two sinks to it: one for the bathroom, and one for a wet bar sink adjacent the bathroom (about 3 feet away).

    My question is, can I use two sanitary tees (one above the other) or do I need a double fixture cross?

    With 1.5" pipe, it would be a double fixture fitting.

    You can't wet vent without increasing the pipe size to 2"
