Studer vent at high altitude.

[Dberryco]

I've tried 3 different studer vents and none are working properly. I'm at 9000 feet elevation and am wondering if that could be the problem as these things might be calibrated for sea level.

Any tips or clues

That's a surprise to me! An AAV should normally be fully closed, and only open when there's a suction in the drain line to admit air.

Keep in mind that for one to work, it can't be the ONLY path to open air...there must be an atmospheric vent somewhere in the system for them to work properly.

Are you on city sewer or on a septic system? What type of Studor vent have you been using? Are you using a true Studor vent or is another type of Air Admitance Valve (AAV) ? They are not all the same and a studor vent cost 3-5 times more than most other AAV's.

What symptom do you see that brings you to that conclusion?

I'm rural and using a septic system. The model is
Studor 20302 Maxi-Vent 3-Inch to 4-Inch Air Admittance Valve

My toilet gives a big burp after flushing which it didn't do before with the original studer valve.

I think you need a real vent. How else will the gasses from decomposition, such as methane or H2S, get out? Right now, the only path would be through your traps and toilet into your house.

I agree a real vent is the solution. Fortunately we don't have any smells. This isn't high on our list as we have limited time to build and are working on our garage. If we could just get it to work til winter when we can't work outside that would be great.

You need at least one vent that is open to the outside ,so gases such as methane ,that are created in the septic tank ,can vent out.
