I posted this thread yesterday and recieved one reply, however now the thread is gone.
Anyway here it is again...
I am building a new home my master bath will have multiple (9) shower heads. If running all heads the shower could produce 22.5 gpm. My plumber wants to install a 2" drain pipe and trap but I was thinking it wouldn't be able to handle a "full bore" flow without creating puddling on the floor of the shower.
Should I have him increase the drain pipe and trap to 3"
Would having a 3" drain/trap hurt anything under normal flow conditions (5-10 gpm)?
The main trunk line is already 3".
Thank you
