Hi all,
I am about to fit a new pedestal sink in the bathroom (upstairs) and I want a straight through trap, so the waste pipe runs straight down the pedestal. (I think) I would like an anti-vac one, but I've only seen these in the smaller 1 1/4" (32mm) waste size, not 1 1/2" (40mm).
What is the best size for the waste pipe of a large bathroom sink? Is 32mm ok, or is 40mm better?
Thanks in advance...
