However, there are a few limitations. This is how a finished installation of an Air Admittance Valve looks as placed onto the sanitary tee of a bathroom sink drain . Moreover, most plumbers recommend this kind of mechanical venting system for kitchen islands, when there is a large window above a sink or wherever a traditional vent would be problematic. Typically, noisy, gargling sinks and slow draining toilets are good indicators that your home needs an improved venting system.
The active air valve is designed with an exclusive vermin protection system to keep out insects and foreign objects. The total amount of the cross-sectional area of vents combined on the system has to equal the aggregate cross-sectional area of the building drain. When properly installed an air admittance valve in the system is equivalent to an open vent pipe having the same cross sectional area as any other vent.

I believer the videos are a newer feature that came along due to COVID-19 situation. Let him do the inspection alone, then review the extremely detailed report and videos with you. Is it possible I add up to at least 2-90’s to each 2″ ABS piping to get it back up to that same attic space that is topped off with an AVV in each location.

How to Install an Oatey Sure-Vent AAV
My first solution was to have septic tanks cleaned and checked, and a local tradesman completed this task and indicated the tanks were in good condition. I have now started to simply replace the AAV in the areas where the smell is identified. The source of smell seems to move within the areas as I replace the AAVs. I have now replaced 5 AAVs with one bathroom sink where the smell will simply not go away.
Sometimes structural blockages or multi-stories won’t allow a vent to be placed on the roofline. In those cases, air admittance valves are another option to consider. Help prevent sewer gas from entering your home while you vent your drain line with the Oatey 1-1/2 in.
