Can anyone give me a diagram of the drain and vent connections for an island sink with disshwasher and disposal. The rough plumbing is in with two (one a 2 in and one a 1 1/2 in) ABS stubs sticking out of the floor. I understand the loop that needs to go in but can't figure where to connect to the sink, dishwasher or air gap. I am also putting in an above counter air gap.
Better check your local code (plumbing) as some locations do not like these types of poorly vent fixtures
Thanks for your reply. Our plumbing codes allow that under-the-counter loop and recommend the above counter air vent but don't require it.
