Bought a book on plumbing, but it doesn't seem to address my particular situation in the basement:
Adding a wetbar right next to the drain stack. No more than a couple feet away depending on how the cabinets all line up...
1) I take it I MUST vent, but then I read some things that indicated distance from the stack was important as far as requiring a vent or not. So, do I need to vent?2) If so, any reason not to use an air-admittance valve since a vent line is not easily accessible?
3) If you suggest not using a cheater valve, I'm trying to figure out how to do a loop valve. All the diagrams I have loop it under the floor, which isn't going to be easy in a cement basement! ;-)Thanks all again!
