1.5" vs. 2" shower plumbing
Posted by John Miraglia on December 23, 2003 at 08:46:01:
I am replacing a 35 year old bathtub with a 3 piece
acrylic shower. I expect to find a 1.5' drain when
I expose the plumbing. Besides the fact that new codes
require 2" drains are there good reasons not hook up to the existing drain.
