As you can see its already in place. Another one of those items that you dont know you need it until you see it on Wayfair. Easily installed with the need of a plumber. I now will have my plumbing vented with this useful appliance

Helps water discharge.

[This review was collected as part of a promotion.] When I bought my house the toilet downstairs wasn’t vented properly. My water would “syphon” and ended up costing me extra money on my bill. A plumber buddy suggested one of these vents , and it solved my problem immediately. Thanks to oatey’s in line vent we do not have a problem anymore!

[This review was collected as part of a promotion.] I recently came across the need for an air admittance valve and got the Oatey in line. It worked very well for the sink. I needed to use it on since the vent was no longer available.

[This review was collected as part of a promotion.] This in-line vent works as it should. I have been going around replacement my bathroom vents as I have been having a plumbing problem. This vent installs easily and is small enough to fit in a tight bathroom vanity.
