Does an island loop vent have to come to a point (45-90-45 bends), or can the top run horizontally for a few feet using two 90 bends and no 45s? I would like to run my island sink drain pipe down one leg of the island and the vent pipe down the adjacent island leg a few feet away. Thoughts?
Other crazy options if the horizontal approach is not allowed... The skirting around the top of the island could conceal a traditional island vent (two 45 & 90 bends) then vertical for 7" and a horizontal run to the leg. Or, one 45, a 90, and a diagonal pipe but I'm still left with a short horizontal section before reaching the leg. Or, can the trap arm connect to a horizontal drain pipe which runs to the drain leg? Thoughts?
By the way, this is a permitted job so it will be inspected.
Thanks for your help!
Based on John's response, would the layout in the below diagram be allowed?
