Hi All,
I live in a house where the previous owner was a do it yourselfer, big time, but did not have a grip on basic concepts like waste lines need vents to work properly.
So I’m retrofitting some of the bathrooms and rather than punch holes in the walls and roof and make my house look even weirder I thought I’d try these in-wall vent valves that I heard about that basically allow air to go into the waste lines but prevent sewer gases from escaping into the living area.
First, what are those darn things called?
Second, has anybody used them? Good? Bad? Ugly? All opinions most welcome.
Thanks,
Santi

The generic name is air admitance valve.
The common brand name is Studor Valve.
if your local code allows installation you should at least make them accessable for future maintnence.

Actually, if you install one, you should make it accessible for future maintenance whether or not the code allows it.
<<The generic name is air admitance valve.>>
The common name around here is "cheaters".
Ive used them a number of times in otherwise impossible to vent situations. I don't think they're up to code here but I've had no problems, seem to work well.
Just came across one in my truck camper today, for the bathroom sink.
BTW, they don't go "in wall". They shouldn't be sealed up in a cavity as they need air to equalize.
