Sink vent
I'm doing a kitchen remodel and have an opertunity to get rid of the "cheater valve" and run a real vent. My question is, do I really need to run 1 1/2" pipe for just the vent or could I reduce it dow...

...........an open vent means you could get precipitation down the pipe that could introduce water into an already winterized system.
Interesting. I never thought about that.
I would be venting out the old propane refrigerator roof vent. It's covered so rain isn't an issue. I'm also sealing that vent up with foam and can run 3/4 pipe up there, then seal around the pipe. I don't have room in the wall for 1 1/2" pipe.
