Doing a bit of work around the kitchen, and noticed the sink drain has no vent. It flows from the double sinks into a P trap, then into a 90 (making it essentially an S trap), and straight down through the floor and into the main horizontal drain. The main drain is horizontal in the basement, and is on septic.
I have no idea if this was legal in the late 80's in PA, but I doubt it. Then again, the laundry tub and washer are basically the same setup (no vents), but I'm addressing that with a different project. So who knows...
While I don't really have any functional issues with the drain (it drains, it doesn't smell), I'm wondering if I should address the issue while I'm replacing the base cabinets.
Options as I see them are:
1- Leave it the way it is (if it ain't broke...)
2- Replace the 90 with a SanTee and add an AAV (easy way out)
3- Move the drain into the stud bay, with a San Tee, and take a vent up to the attic (2 floors up) and tie in to the vents. There are no other vents nearby, just drain stacks. The sink is, as usual, under a window. If I go this way, I would plan to route the vent under the window, rather than moving the entire DWV to the side, and using a longer trap arm. But I could do either. (both are a lot of work)
Thoughts?
