20340 Mini-Vent Air Admittance Valve with ABS Adapter, 1-1/2- or 2-Inch Connection

Works like it should. been installed for a few months now and no issues.

Quality product and brand. Previously, we purchased a off brand, cheaper vent from our local hardware. That valve only worked 50% and for 6 months. This valve immediately allowed the proper air flow which resulted in drain emptying. Easy installation.

Not need to cut a hole in your roof anymore. Never smelled anything in the past 2 years since the installation.

Easy to install and worked perfectly.

Works as design! But I only need filter potion! Black pipe is wasted!

Worked well

I did not know about these in a camper. I thought the smells were from the black tank. till i opened bathroom cabinet and the smell hit me like a ton of bricks. Changed this out and no more smells!

Easy to install and helped me avoid another vent through the roof.

Das ist die beste Alternative wer hat keine Abwasser Ventilation gemacht.

Worked perfect for our project

Tres satisfait, commande rapide , livraison rapide, produit de qualité

it solved the problem with smell in our Rv pipes , we replaced the old, probably $3 home depot vent with this one all good so far

Great vent
