AAV for Tub/Shower OK?


The inspector told me today I can use AAV's under the 3 sinks I'm putting in, but I forgot to ask if I can use one for the bathtub/shower? Any problems there?

Thanks!

You cannot use an AAV inside an enclosed wall space. Under a sink is OK as the air gets replenished for the AAV to use. There won't be air replenishment for the AAV if used for tub/shower once the original air trapped in there gets used up.
You'll need to run an vent the old fashioned way.

If I vent inside a wall, with a register in front of it, that's OK.
But I was thinking of putting it at floor level in a built-in closet at the end of the tub. I could add a register there as well to allow it to 'breathe'....
