|In response to Re: RE: AAV better with nothing???|
If it backs up into the tub, then it would happen regardless of the type of vent used. But if the line is just partially stopped a sink with a conventional vent will still operate, whereas an AAV vent will prevent drainage of the sink.
: : : : Plumbing inspector recommended the use of AAV's in two locations in new home construction. He stated to stay away from the "cheap black ones". Does anyone know what he is referring to and are there any recommendations on what could be considered a "good" AAV? Thanks.

: : I am curious what plumbing code the poster is under. Is this another instance of the inspectors organization, the ICC, getting their International Plumbing Code adopted in their area?
: I've got an 1890's farmhouse and I have one of these gizmos installed on my basement utility tub. Short of shooting a vent up and out through 2 floors and the roof, is it better not to have one?? What problems disasters can I expect to face, ie during a main line back up does it somehow force its way out my tub? versus the drain trap in the floor, where this normally occurs when I need snaking....thanks for all input...
