OK, so I've done a lot of research on this but can't find a definitive answer. What is the best way to tie in a bath sink (on the second story) to an existing waste pipe that sits under the floor?
I was originally going to use an S-Trap, but am reading those are illegal, so my only other options are:
(1) to tie in the P-Trap directly under the sink and then run straight down (is this a modified S-Trap?), or
(2) run straight down through the floor first and put the P-Trap under the floor.
Neither seems ideal, but was wondering which is better and the pros and cons to each. Are there other options? FYI, either option will be vented below the floor.
Thanks in advance!
