I am mechanically inclined, but I found this a worthy story to tell: It is amazing what happens when one of these things MALFUNCTIONS and doesn't open. QUICK BACKSTORY: Wife said " The kitchen sink is plugged up". So, I look, and sure enough is is backed up all the way into the sink. NO leaks under the sink. I auger the drain down to 25 feet and I DO get some stuff out. It runs clear for about 20 seconds, then backs up into the sink again. OK, so the clog moved beyond 25'. I buy a 3/8" 50' Auger and go all the way. At 50' I AM SURE I am into the main 6" drain which CANNOT be the problem since all the other fixtures work fine. Then I start thinking about how over the last couple of YEARS, I would occasionally get a sewer smell at the bathroom sinks and I notice that all of the sinks have one of these little gadgets on them. Until I moved into THIS place, I'd never seen one before. I manually press down on the spring assy in the kitchen one and the drain opens, water drops like a rock. MY GOD! it was this thing????!!!! But HOW? It has a weak spring to keep it closed BY DESIGN! 4 to 5 vertical feet of water SHOULD open it EVERY TIME! The answer: a little SLUDGY goo. Hardly enough to mention. BUT JUST enough to act like a ring of vacuum grease and prevent it from opening. THAT and I believe the units that are in there are NOT the proper ones and many years old. REPLACED ALL OF THEM since they're so inexpensive, and guess what: NO funky smells in the bathroom sinks and NO MORE CLOG. NOTE: I specifically picked THIS one because the other brand,(Jones Stephens P21-150 Auto Provent, 1-1/2-Inch) which looks similar AND is exactly like what I had in there, states that it must be 60 (SIXTY) inches MINIMUM above the trap elbow. I also confirmed that on the manufacturers website. MY installations are 8" or so above the trap. THIS one has a longer very thin spring which should translate to weaker valve pressure which in turn means LESS vacuum for it to open. As such I suspect it is indeed designed for a normal under-sink install. Hope this helps you :-)

I recently purchased this inline vent to address some plumbing issues under my sink and in the basement. From the moment I installed it, all my problems were resolved.The inline vent is built to last and the quality is evident in its sturdy construction. Installation was a breeze, even for someone like me who isn’t particularly handy. The step-by-step instructions were clear, and I had it up and running in no time.Since installing the vent, I’ve noticed a significant improvement in the performance of my plumbing system. There are no more unpleasant odors or backflow issues. It’s truly made a huge difference, and I couldn’t be happier with the results.Overall, I highly recommend this inline vent to anyone facing similar plumbing problems. It's effective, durable, and incredibly easy to install. Five stars!

I bought this last summer but waited until now to replace. It won't work for the drain vent under my bathroom sink. It is too tall. There is no room to get it in without removing the sink. Then the sink probably will not fit.

perfect and works well

These are affordable and easy to install, and the quality appears to be well made. I had to replace the vent in my laundry room because the smell from the septic was coming in and it fixed the.

Works great and cheaper than most of the other brands. Definitely recommend

Good product
