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

Very reliable valve. Costs a bit more than others but it will last for years before needing to be replaced.

Works well, prevents expelled water from returning to well.

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.

Easy to put in. Works as it should

I use this check valve with an old Zoeller pump that came with my (also quite old) house, with about 7 feet of head. I note no issues of hammering noises or such, as installed, with 1.25" corrugated flexible tubing heading outside. I can see how it might easily be an issue for those who have rigid piping, though, since things do move around a bit when the pump stops. The only issue I have, which would happen with any check valve in my case, is that the discharge line freezes solid in the coldest Ohio weather with this old, drafty house (and its purposefully-cold basement). Removing the check valve solves this issue, as it allows the line to drain completely after each cycle. So, in the spring, I put the valve in (to save the energy of refilling the line, and increase the time between runs). In the late fall, I remove it (to keep the lines from freezing). The clamps and adapters included with this pump make this job a breeze, and show no signs of wear from these regular changes. I've only had it for about 3 years, but so far, so good. If or when it ever shows any sign of failure, I'll buy another one just like it. Edit: It has now been 5.5 years. Still working fine, still no complaints.

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.

came on time and was in good

the title of my review sums it up pretty well. these check valves operate silently. there's no clunk or water hammer effect like i had with my old valve. you only need a standard screwdriver for installation if you're replacing an old valve (and maybe a saw if you need to cut away some of your pvc drain pipe to allow for the proper fit). there are arrows printed right on the valve to help you install it so that it opens and closes in the correct direction, just in case you couldn't figure it out on your own. i actually got two of these when i added the Wayne ESP25 12-Volt 3300 Gallons Per Hour Battery Back Up Sump Pump System to the pit with my primary pump. i'm no plumber, but install time for the new pump and both check valves, plus new drain lines out of the house, was less than 3 hours. installing these valves was one of the easiest parts too. i really don't think there's any reason to use any other check valve for a standard sump pump setup. the price on these is great, they're built very well, and they don't wake me up at night with all the clunking. great investment!

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!

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.

Much better than the check valves from the Orange or Blue hardware stores! They're a lot longer than the normal check valves, so you will likely have to adjust your pipes a bit. The rubber no-hub union is a good length, so it can tolerate a bit of imprecision in your pipe setup. Clamps are nice and solid, the rubber boots are good. While the check valve body is still plastic, it's a thicker plastic than others I've used, seems like it will hold up better. Price is competitive, order a spare and keep it on the shelf just in case something happens. Haven't really listened to it for noise, my pump is far louder.

The bad part is that there is only one unit not as the two shown. It's good I got the taller one as it barely fits in the gap in my pipe. Installs very easy and is working fine. Let's hope it lasts a long time.

People of Canada...this is a terrific, inexpensive check valve that far exceeds that noisy, cheap, failure prone junk you can buy at Canadian hardware stores. I've bought a few from Bur Cam, Flotec, etc, they all seem to be the same generic design, but I can't confirm that. Either way, I get about 2 years out of them, and they are quite loud in normal operation. This check valve is built like a tank from a reputable sump pump company. I can confirm it is whisper quiet in operation when placed inline vertically. The company literature and manual both mention vertical installation too, so no worries. I don't know why it isn't sold in more accessible places in Canada but, their loss is Amazon's gain. Highly recommended.
