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.
