I'm new here, just recently ran all new plumbing through my house and am now at finishing stages and trying to figure out how to run my trap outside of my sink cabinet basically. I have full access behind the vanity wall inside the furnace room.
I'm wondering if by code I'm allowed to turn 90 directly below the drain then run about 12" horizontal and then turn 90 downwards to drop another 12" directly into the trap.
In Ontario, Canada by the way.
Thanks for any help in advance!
