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...

I think (don't quote me) vent pipes must be at minimum, 1/2 the diameter of the pipe they service.
A 3" main drain would need a 1 1/2" vent. I don't know if this would apply to a RV because of the short runs of pipe.
Hopefully someone will correct me if this is wrong. :)
