I bought this after the install of my well, and connected it between the pressure tank and the pitless adapter. Works great, easy to install, no leaks! Great buy for the money.

I bought this for my lawn pump. It doesn't have a foot valve and only has this midline valve to maintain the prime in between uses. I only use the pump once every week or so. Previous plastic valves did NOT work. they leaked and the pump would need to be primed for every use. This valve did the trick! I highly recommend.

The valve seems to be made well. Hopefully the interior materials are durable. I have used thousands of 1" check valves on submersible well pumps. I'm using this 3/4" one on a geothermal heat pump.

This unit is built to last. I am very happy with the quality of this check valve. Even though no check valve gasket can forever withstand the sand and calcium particles (from my water softener) in my basement sump, I still expect at least ten years or so of reliable operation.
