Need some advice for a first time DIY plumber here.
I'm roughing in drains for a double vanity. I'm using 1.5" drains from each traveling horizontal in the wall to meet a 1.5" vertical drain, with a vent going up from that. The bathroom has a 3" waste pipe that runs perpendicular to the vertical lav drain pipe, but is not directly below it. Can I use a 90 degree elbow or a 90 degree long sweep at he bottom of the vertical drain to then tie into a wye I'm adding to the 3" waste pipe?
Staring at the sink wall, the vertical drain would hit the 90 degree elbow and come straight out towards you, and then tie into the 3" waste pipe. Is the 90 appropriate?
