Rated 1.9 out of 5 by 14 reviewers.
Rated 1.0 out of 5.0 by Fails after 1 week, don't waste your money I bought two of these within the past year, both failed within a week of installation. They barely work for a week, are incredibly noisy and make the pipes shudder. Then after day 4, they start slowly leaking back into the sump. After day 7, they hold back no water at all. The problem is that the valve flap seems to be held on by two little drops of glue. It is not permanently attached to the body of the valve in any substantial way. I can't believe that HD would allow this to be sold at their store, especially at such an excessive price. I will be taking my second valve back, sewage residue and all, and asking for a refund. I'll then buy one somewhere else, since this is the only model HD had in stock at the time. In my photo, you can see the flap has become completely dislodged after just 7 days. November 26, 2013
Rated 5.0 out of 5.0 by Excellent product for the price. This back water device works great, before the sewer waste backs up into condensate drain for the boiler and made a mess. With this device the problem was solved, no more back water /sewer waste. November 21, 2013
Rated 1.0 out of 5.0 by Terrible product Not only did this unit fail in 30 days, the rubber stop valve inside broke off and proceeded 25 feet down my plumbing system and clogging my system. DON'T BUY THIS ONE!!!! The little extra money for a high quality unit will save you!!! The HOME DEPOT should discontinue this unit. June 27, 2015
Rated 1.0 out of 5.0 by failed in two weeks installation was easy, however, it failed in two weeks, looking for a good replacement, any recommendation? February 15, 2015
Rated 2.0 out of 5.0 by Slow leaker I purchased this check valve for use in a lake-water irrigation system. The valve never sealed properly, slowly allowing water to seep back to the lake and losing the prime for pumping after several hours. At first it was very slow, but after just a few weeks it failed entirely, not functioning at all. I removed the valve and could see that the valve flap seemed to have dropped from it's original manufactured design, and a seal was not possible even when closed. This weak design appears to be very inadequate, and I'm only happy it was lake water and not sewage that was back-flowing. I replaced it with a Flotec PVC check valve I purchased at my local Home Depot store. This new valve worked immediately and solved my pump-prime problem. It's been working for a few weeks now with no problems at all. July 23, 2014
Rated 2.0 out of 5.0 by Emergency Shelved Item. I have not installed this item. It is on my shelf for Emergency Replacement when necessary. October 8, 2014
Rated 2.0 out of 5.0 by Does it's job, but loud & shakes pipe I installed this valve about 5 years ago in my basement bathroom installation between the sewage pump and waste line. I gave 2 stars only because it never failed me, it's always worked properly. However for my own peace of mind I just re-piped the pump to the sewer for a more permanent installation before I finish my basement. When the pump turns off there's always been a significant kick in the pipes causing them to jump sideways, as well as a loud bang when it closes (audible across the house). I do have to say I have it installed vertically. I doubt it would do this if mounted horizontally. But it says either direction is acceptable. So I searched and found some quiet valves on amazon for a couple dollars more, with near perfect reviews with both horizontal and vertical installations. That's your best bet. March 18, 2013
Rated 1.0 out of 5.0 by Did not last I purchased two of these for a sump pump application at my church. After just a month or two the rubber flapper on both check valves failed. One was found "just hanging on" inside the check valve casing, while the other flapper was not found. It must have been " blown" into the pipe taking the water out of the building. The rubber flapper appeared to not be strong enough to handle the water flow. May 9, 2012
