In the midst of a rehab of our laundry room. Picked lots of good info about venting here -thanks, Terry for the standpipe/sink picture! (lots of sweated joints- I learned about taking your tme, cleaning the fittings, ..., after redoing it several times - but passed an air test yesterday.)
In CA, under UPC, need 2" drain for a laundry tub. Ok, put a 2" drainpipe in the wall. But most of the drain assemblies I see have a 1.5" tailpiece, which one would presumably feed into a 1.5" ptrap - does this comply , ie is the 2" req. only for the pipes in the wall?
Thanks!
