Zoeller 30-0181 PVC Plastic Check Valve, 1-1/2 Inch

I bought my home and in the inspection was a "Faulty check valve" on one of my sump pumps. It was a PVC kind that was probably around $3.00 at your home store. I have never lived with a sump pump before so the noise that would come from this pump was startling. It was extremely loud even on the second floor of my home. It was odd too because my other pump already had one of these check valves on it and didn't make that loud hammer noise! Based on reviews here and that I already had one, I decided to try another one for my problem pump. Install couldn't have been easier. Done in about 15 minutes (excluding the trip I had to make to Lowe's to get an adapter). The valve comes with couplers that are 1.25" on one end and 1.5" on the other. The problem I had was that the sump pump discharge pipe is 1.5 pvc and north of the check valve is 1.25 copper. So for the top part I needed a straight 1.25 to 1.25 coupler. After installing this (and literally, if you can turn a screw you can install this) i filled up the sump crock waiting to still hear the loud hammer... But no hammer was there! I could barely even here when the water hits the check valve when I was standing right next to it. Can't wait until I'm three floors away to hear the difference but I doubt I will get to appreciate it because it is so quiet. I will have no clue the pump has cycled on unless I'm in the basement. Great value and great quality.

Love it works great, replaced an old plastic one. It’s quiet and works as stated. I would buy again if required but this one has been installed and working for 3/4 of a year without issue!

I have bought a lot of check valves and this one has not broke yet. Usually the ones you buy in local stores only last maybe 6 months. I have an extremely extremely extremely very high water table. 6 months ago they dug a new basement for my new addition and the builder was in shock. dug the basement and then left for 12 hours and had a full blown pond the next morning. So this check valve is the #1 best in my book period. my sump pump in new addition was kicking on every 20 seconds for months. for the existing portion of the house we have 2 sump pumps that are kicking on every 3 to 5 minutes especially if the ground is moist or raining. kicks on every 10 minutes if so called dry outside. and YES I have it set below the holes in the sump pumps to kick on so the water is not filling the lines up and making it work twice as hard. This check valve has last the longest so far. I bought one Zoeller check valve from amazon and one Zoeller check valve at Walmart on the same day and just waited to see which one was going to get here the fastest. I had 1 sump pump shut off because the local store check valve tore again and water went every where, so that made the other one in existing portion work twice as hard. I didn't want both to go out before the NEW check valves got here or I would have a pond in my basement. Then I replaced them and I am a happy camper now.

Was a bit leery of getting something that wasn't sold or supported by Amazon, but it was a great buy. As others have said, it is a 5 minute job to install and it is absolutely silent. My contractor initially said my hammering was due to my sump pump, but I figured it was likely due to the water hammer with my check valve and I was right. I was thinking of somewhat more expensive "silent" check valves, but I'm glad I picked up the Zoeller - it has been silent (the water rushing through the pipes is louder!). Also, shipping was fast (I bought it in the GTA), fwiw. Have had it running for a few months now w/ no issues.

I'm very pleased with this check value. I know that it's not a very exciting product to use (or even talk about) but it is so good it warrants a review. It replaces a check valve that still works, but has always made a loud bang when it operates which could be heard one floor up from the sump pump. This is very quiet in operation even when standing next to it, and certainly can't be heard on the next floor of the house. The flap valve allows for full flow with no bottleneck. It comes with four hose clamps that are of good quality. The housing is plastic, but thick enough that it is sturdy. Very easy to install. Outstanding quality and functionality at a great price. Highly recommend.
