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.

Well made, more reliable than pvc versions
Worth the extra cost over pvc valves: I’ve had too many failures with the latter.

Works well and lead free
I use this 1 inch line when I am filling up a pesticide tank for spraying so I thought it might be a good idea to have a backflow valve on this line just in case. Works well.

Decent price/quality
Works exactly like it should, screwed on easily, allows water to flow easily. Used teflon tape and had no leaks. There is no noise like you get with some backflow check valves. Great value. Dont know how long it will last, but seems to be made of decent brass. Not the best, but far from the worst.

Durable and Affordable
Great quality, and competitively priced. I used it as a replacement and there was zero leakage, great flow rate and the installation was standard. It's my go to brand for check valves now!

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.

Good Brass Check
These threads were correct and these worked well for separating two alternating light pressure lines. i actually pulled the spring out of one of them because of the low line pressure coming in to that check to help the pump out. it works well because the disc inside floats easily and seals.

Great Value
Perfect replacement for a failed check valve on our home well. Now, several months later, it's still working as intended. Great value, easy to install.

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