    Air Admittance Valves use applications
    Hello,

    Are Studor Air Admittance Valves (AAVs) approved for use with toilets or can they only be used to vent sinks?

    I have a toilet waste line that connects with the sink waste line. Out of the sink line is the stack vent system but it has been built into a wall chase. I'm keen or relocating the stack or possible doing away with it in place of a Studor just due to it's location in the bathroom. I suspect I cannot vent the sink and the toilet on a Studor valve however.

    You can but a natural vent's better. If you choose yo install a AAV you will have to leave a service panel so the part can be replaced in it goes bad. You just can't cover it up inside a wall. If there were any other way I would advise you to reroute the vent you now have. Good luck Tom
