Have a dual bowl kitchen sink with disposal centered beneath a bay window, which prevents me from using a traditional vent as the window is 40" above FFF so I cannot make 6" above the rim before the vent would need to turn horizontal. Seems the only options are AAVs (no thanks) or a loop vent.
I cannot use a dual fixture fitting to serve both sinks because there is an electrical outlet blocking the central vent. Also, due to a thick old foundation wall immediately below the kitchen, there is no room for the usual below-floor horizontal leg of the vent or for that matter the 45 elbows and wyes that connect the loop to the drain.
Shown below is my proposed solution.
Questions:
1. Is a loop vent permitted in other (non-island) installations?
2. Can this all be enclosed in an exterior wall?
3. OK to have the horizontal vent tie-in above the floor?
4. OK to have the drain and loop connect to the 2" drain using Sanitary tees on the flat?
5. OK to have the horizontal portion at the top of the loop vent instead of the usual 90 degree elbow peak?
Thanks in advance and I'd appreciate any simpler or superior alternatives.
