Can an Oatey Sure-Vent be installed outside?
No. The Sure-Vents are not designed for exposure to Ultra Violet Rays.
Can the Sure-Vent be installed in the attic?
Yes, with exceptions. The attic has certain conditions that can affect the AAV performance which should be considered before choosing this as a location. The temperature ranges that the Sure-Vent will operate in are -40°F to 150°F, your attic can experience drastic temperature variations depending on how it is vented and your geographic location. Insulation fibers can get caught inside the diaphragm which will make it harder for the diaphragm to open, or achieve a good seal when it is in the closed position. The Sure-Vent should be installed a minimum of six inches above the finished height of your insulation, and the attic must have an access point to conduct scheduled maintenance.
How high above the fixture trap should the Sure-Vent be located?
A minimum of four inches above the horizontal branch drain (trap).
