Adding a wet bar to basement, tieing into main drain stack
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! |

Depends on your locally adopted code. I'd allow it but others might not. The vent is required regardless of distance from the stack if it is draining waste from a higher floor. Dan |
