Long time listener, first time caller.
I am finishing my basement but the one area I lack confidence is plumbing. I am looking to verify if what I have planned is acceptable. Framing is complete - The bathroom wall shares a wall with a wet bar on the other side.
I have a 2" stack coming from the basement slab and plan to have a urinal, bar sink and bathroom sink on this line. I plan to run a 2" line to the Kohler urinal, and a shared horizontal drain line for the bar sink and bathroom sink. I have quickly sketched a drawing (using square, not circular pipes - sorry) and will use all correct fittings and slopes - However - is there an easier way to vent instead of using 2 vents on the sink branch?
The distances are 48" from bath sink to bar sink and then 48" from bar sink to main stack. Could I have a vent between the bath and bar sink (42" for 1.5" pipe) if the bar sink is technically downstream from that vent by a foot or so? I have read and read and cant find the rules for upstream vents so im not sure if its assumed that the 42" to vent is ok or not?
Anything else I should be aware of?
17.5" for urinal from floor to drain
18-20" for sinks
Vents will all be 8' or higher to tie into main vent before a horizontal
reducer from 2 to 1.5 on main drain stack.
Thank you in advance!
