Great product
I use this check valve as part of my hot water recirculation system, and so far it has been working well.

Worked as advertised. Would recommend

Good quality and as expected.
Cracking pressure in description is accurate, I can barely blow it open if I blow extremely hard. Did not leak at all, and the valve seated well. Good quality. Correct size.

Waterflow not as good as it should - you get what you pay for
water flow is not optimal - i have not really measured it, when i replaced it with a different one it worked much better

Solid, Well-Made, and Works Exactly as Expected
Solid, Well-Made, and Works Exactly as Expected This check valve is high quality and easy to install. The brass feels durable, the threading is clean, and it sealed perfectly with no leaks. Once installed, it did exactly what it’s supposed to do — prevented backflow and kept everything running smoothly in my RV’s water system. If you need a reliable in-line check valve, this one is definitely worth it.

Works perfect had to use it to limit flow to one way so my reverse osmosis didn't draw from both sides
