Air Admittance Valve Trap Assembly Kit with 1-1/2 inch Tuuber Vent 2x Superior Seal Air Admittance Valve

Quality of pipe & fittings - especially the neoprene gasket washers is superior. The ones I removed were the standard Big Box store clear plastic washers (one of which I found split prob. from overtightening). These new ones fit snugly and seal well. I installed the entire drain system by hand. Only needed a rag for drips at initial disassembly of old drain. No tools used - I swear just hands. Now - did it help the drain - drain faster, YES. I never had a serious issue just a bit slow. I like these so much, I've ordered two more for the other vanity & the guest bath, they have the same issue, a bit slow. My only issue is price really $45. It's like everything, want it right, you have to pay.

Very easy to install. Working!

This was exactly what I needed when replacing my kitchen sink - except for one small detail...The height from the drain in the wall to the bottom of the sink did not leave enough clearance for the air admittance valve, so I had to cut the riser pipe down about an inch. 4" is what it calls for, but I figure 3" was better than no vent at all. Other than that (which I should have checked before buying my sink), it was a simple install process.I like how it includes all the pieces needed, including various extra pieces for adapting to your specific situation.

Fit worked. Leaked a little. But just adjust it where it tightens. Good product

We have a vent for the kitchen sink, but it got closed up in the wall, and would require major surgery to access again. This air admittance valve works fantastic. Before installing, the water was very slow draining, and would back up between the sinks. Now water flows / drains perfectly. Had to make a minor adjustment to the main drain line (height), so it matched up properly, but yeah. Awesome product

Installation was easy and this thing works great. My problem was insufficient draining due to a defective vent somewhere down the line. And it's inaccessible without tearing my home apart. My sinks have never drained so well.

I bought the TUUBER air admittance valve and trap assembly kit because I could hear gurgling from my kitchen sink as the horizontal run from it to the main stack is too long and it was trying to vent from the sink. While the gurgling never emptied the trap enough to allow sewer gas to escape it was still a concern.The reader of this review, unless they've done a lot of DWV plumbing, should be aware that quarters are tight under sinks and attempts to work on their plumbing often encounter complications. Notwithstanding this I took on the project as a DIY anyway and had this installed in short order without issues. I used the supplied new loop of the trap to replace my seemingly identical existing one to upgrade to new instead of 18 years old. Coming off that was the new tee with the TUUBER air admittance valve coming off the top and 3" of the long straight pipe with both new rings and gaskets with it and the tee replacing the 18 year old stem of the P trap.One helpful tip is once you pull out any existing drain piping immediately put a plastic bag or plastic wrap, secured with a rubber band, over the drain pipe exiting the area. Don't take it off until you are ready to connect to it and plan your install to make this the final connection. This way you'll minimize your exposure to sewer gas.The final tip is that this kit comes with lots of parts to be versatile for many different installations. I suggest that you use as many of them as reasonably and easily possible to replace your old parts when doing the work.Would I buy this again? Everything depends on the space and plumbing situation. This was absolutely the right product for this particular situation with a P trap and a horizontal connection to the rough plumbing. A competitor offers a direct swap-in combination trap and air admittance valve all-in-one but it's not suitable for this P trap configuration. If I were dealing with an S trap with a vertical connection to the rough plumbing I'd have bought that competing product.

This magical product replaced a leaky and stinky sink p-trap and is working well so far. Excellent value for the money since it includes all the fittings you would need to get the perfect fit. The videos in the image gallery are very helpful to understand how to assemble the fittings.Take a picture of your current setup so you can reverse engineer the assembly you will need.So far so good! This looks like it will last. Buying more for other sinks that need it in my home.
