Good Quality
I installed this check valve on my well system and it was one of the best things I could add it helps keep the water from going back down the line which helps the pump work better and last longer it was pretty easy to install and the brass feels strong and good quality I also uploaded a picture of my setup overall it is a good upgrade for a well system and worth installing (I don’t know if it’s installed right but it did the job)

High-quality and works great for our well system. Have had this for over a year now and still working great. I highly recommend this product as it is as described and size is perfect. The price is cheaper than local stores. I will purchase again for clients from this seller

Works like a charm
Hooked it up to a bladder tank on my 12 Acre property on Malibu. Now we have running water full time in our Cocoon. Shower, Toilet and the sinks.
