## Description

Air admittance valves can be used to vent branch and stack plumbing system drain in a home or building.The purpose of an air admittance valve is (1) to provide a method of allowing air to enter a plumbing system as an alternative to a vent extended outside a building to outside air (2) to prevent plumbing system sewer gases from entering inside a building and (3) to protect against siphonage of a plumbing fixture trap. Is the TUUBER air admittance valve the right choice? The TUUBER air admittance valve is the only patented dual sealing air admittance valve that offers 2x the superior seal to prevent sewer gas and odors from escaping into a home or building. The valve opens to satisfy negative pressures that can develop in the plumbing drainage system when the fixture begins to drain allowing air to enter the plumbing drainage system. The valve has two seals that close by gravity at zero (0) differential pressure, and under positive internal pressure and in low-pressure conditions. The valve can be used in new or existing applications as a secondary vent alternative to a vent extended to the roof outside The valve features:  - Exclusive triple flow passage with dual (2x) superior sealing capability.  - Un-matched increased flow attenuation. - Sound open and close operation.  - High pressure seal. - Limited Lifetime Warranty. Includes: Manufacturer Support, Warranty and Installation Instructions.

## Questions & Answers

**Q: can pipe dope be used or Teflon fkr threads?**
A: Can be used but not recommended and not needed.  This is just a vent to allow water to drain.

**Q: Can this be used outdoor?**
A: [I'm not a plumber.] But, I don't see why it couldn't be used outside.  The seals might be more prone to wear if exposed to the weather.

**Q: What is the dfu rating?**
A: From their website:  “174020  -  2" Dual-Seal 20 AAV maximum DFU rating Individual and Branch 10 DFU, Stack 12 DFU”

**Q: can you just screw it on or is teflon tape required to seal the pipe threads?**
A: a little tape never hurts but not necessary.
