    Horizontal Island Loop Vent?

    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...
