## Description

Oatey? Sure-Vent? 20 DFU Capacity Air Admittance Valve's one-way valve allows air to enter the plumbing drainage system when negative pressures develop in the piping system. The purpose of an Air Admittance Valve is to provide a method of allowing air to enter the plumbing drainage system without the use of a vent extended to open air and to prevent sewer gases from escaping into a building. An Air Admittance Valve is a one way valve designed to allow air to enter the plumbing drainage system when negative pressures develop in the piping system. The device shall close by gravity and seal the vent terminal at zero differential pressure (no flow conditions) and under positive internal pressures.

Review: Cons: a bit expensive for a few ounces of PVC and a diaphragm. But you're not simply paying for the material, testing had to be done on these to make sure they work for a long time keeping sewer gas out of your home. Also, I really wish they would make these in 1.5" as all my non-toilet p-traps and drains are 1.5", in the 3 areas I'm utilizing air admittance valves, space is precious and I had to waste a few inches on a 2" to 1.5" reducer. Note: you do want the valve to be 4" higher than horizontal trap run, so it's not like you'd be able to 90 up and go straight to the valve anyway. Pros: quick and easy to install.... easy as any other pvc connection. I'd suggest looking into local plumbing codes to verify if air admittance valves in general, or this product in particular, are approved substitutes for venting. My local codes specifically list this product as approved with a few clauses. I have an existing 3" cast "main" vent, which qualifies this product for use where adding a vent would require opening up a lot of wall space, and a few other details. This was the perfect solution to the b.s. horizontal vent termination out the side of my house done by previous homeowners in the kitchen and complete lack of venting for my bathroom sink and tub. .... word to the wise and those not already high on pvc cement: do NOT test the valve by using your lungs after you've cemented any fittings or pipe, but before connecting to existing system. If you're so inclined to do so, be certain fumes have dissipated. *ahem* not that I would be so foolish to do so, but even after 15 minutes of dry time, there might be enough solvents in the air to cause considerable discomfort and likely damage to the lungs. Worked though, admitted incoming air, but stopped outgoing.
Review: Worked great. Just what I needed. Drains better than ever.

## Questions & Answers

**Q: If waste water backs up in the system, does this device have a check valve to stop water from flowing out?**
A: No

**Q: Can this item be used with a saniswift  pump.
How is it attached**
A: This item is just a vent with a one way valve that lets air in and keeps sewer gasses out. From what I now, it can be used under a sink inside a room, so if your pump is for a sink, should be used wherever you would have placed the vent pipe. I used mine outdoors. It is pvc glued, has an adaptor, see description. May want to consult local building codes to see if allowed in your area. Do not know if able to vent a toilet, if that is what you are doing. A sink should be ok. good luck.

**Q: will this prevent sewer gasses from comoing out the septic vent pipe**
A: This worked for me.  I was having a horrible odor and nothing was working.  After a few phone calls to knowledgeable people I discovered the little things wear out or get clogged and need to be replaced.  Worked for me and I have not had any problems since I replaced it.  Not difficult to replace.

**Q: Would this oatey be a good aav for my kitchen sink?**
A: Yes this will work very good in that application. I used in a small sink cabinet in my bathroom and it vents all the fixtures excellently!
