Review: Everything you need for $20.72 and by installing them under the sinks they stopped the syphoning out P-traps not easy accessable - Awesome product and unlike some others on sale at desertcart, you get everything you need to install them under sinks, including the AAV. We ended up in a new area where we didn't know many people and hired a bad general contractor to build our dream home. He ignored the advice of a good plumber that told him there needed to be a lot more wet vents going through the roof, and hired a plumber who would do what he wanted and only put three wet vents in our house. Some fixture vent pipe had to travel 15 feet to get to a vertical wet vent pipe, where they recommend they travel no more than 5 feet. When our clothes washer or dishwasher expelled their water, it would suck the water out of the both the shower and the bathtub drain and then we would get major sewer smelling coming up through them. We had to duck tape them closed every time we used one of the washers. What no plumber or internet page, I could find, would tell me, was adding these vents to into the same vent system, but not on the fixture who's p-trap was being syphoned or the fixture causing the syphoned (washers) would help keep stop the syphoning. The only easy place to install these was under the sinks and it worked! No more syphoning and sewer smell! Saved $1,000 of dollars not having to pay a plumber and carpenter to install more wet vents.
Review: Complete kit - This is a nice, all-in-one kit. I thought I would have to install a separate AAV to remote a utility sink away from the plumbing stack in a garage. This kit works perfectly. All the necessary adapters and gaskets are included (you may need a different tail pipe for your sink, which I did.) It's plenty adjustable. Ensure your rough-in drain pipe (1-1/2" DWV) is >7" below the bottom of the sink basin to fit the AAV height which is 4" above the drain pipe. I bought this kit prior to roughing in my drain line so I knew the clearances and could pitch the line properly. The AAV isn't super-high quality (Oatey and Studor offer different styles) but for a single sink, it works well.

### ⭐⭐⭐⭐ No magic, WTF?
*by B***R on December 6, 2016*

My kitchen sinks drainage have been getting worse for a while with VERY slow draining or a gusher when disposal was turned on (like old faithful but it smells worse). So, I took trap and pipes off and made sure they were not blocked. Then a call to a plumber to snake out the sewer line with a pretty long snake (would make a T shirt: "plumbers have long snakes"). Didn't find a clog. He suggested an air admittance problem with a $1 or 2K fix if his outfit did it. Being a cheapskate, I ordered the Oatey valve and put it in to address that possibility. It tested OK before install, that is, the valve opened and closed very easily/reliably when slight vacuum or pressure was applied. The Oatey valve installed easily, and components were good quality. Unfortunately it didn't solve the problem so no 5th star. And there wasn't an instruction/hookup sheet included and although a simple device there are things to know (need a least a 4 inch distance of valve above the drain line, valve must be carefully placed in a true vertical position) and maybe I needed to know more. I can't fault the product design but the magic didn't work for me.
