Customer Questions & Answers

Can pipe dope be used instead of pipe thread when installing studor vent?

I was told putting one under my kitchen sink may help odor coming up when using washer

No roof vent on high side (kitchen area), odor only when washer emptying, gurgling /odor in kitchen sink, some suds noticed in bathtub drain (connected by wall), have done water pouring in all other drains and still happens
Asked by: Jystascrub39
This valve is made for air flow to enter, not exit. If your sink is bubbling when the washer empties this device will not help. Drainage piping from your house is undersized or needs cleaning as it may have a build-up of grease and other debris that has the diameter reduced.

Is it possible that the Studor Mini Vent Adapter ,after a few years ,need replacing???
Asked by: RanloSr
Technically they should not need replacing, but every once and a while one from any manufacturer will have an issue with the seal and need to be replaced. ALWAYS make sure you install it where you can access it again in the future. In other words, Do Not Bury It!
