20342 Maxi-Vent Air Admittance Valve with Push-Fit Rubber Connector, White

Fits great easy to install and there is less odor.

GOOD PRODUCT, EASY RETURN.

i was having an issue with a basement bathroom with a rear eject toilet connected to an ejector pump. the bowl did not empty on one flush, needed several attempts. i located the issue to being not enough air coming in when flushed, since when the standard air admittance valve was removed from the riser it flushed well. i replaced the two riser vent pipe standard air valves with these and it works perfectly now. more air is coming in to allow a full flush. i highly recommend the product.

Works perfect, remodeled upstairs bathroom and moved toilet so old vent wasn't going to work anymore. Decided to run drain down old laundry chute. Added this in there also rather than penetrating the roof, no smells and all fixtures drain well.

Easy installation. Can easily be attached to pipe with the use of a rubber coupling.

Works.

Item arrived earlier than projected. Was very easy to install. Works perfectly.

We used this on a huge plumbing job and the unit would not work as described and it was too late to return. What is the warranty on items like this?

Using it inside my shop. Works great. No more smell.

As advertised

excellent
