Rated 4 out of 5Â by KSF48 Check valve/non return valve
This valve is ideal to solve an imbalance of water pressures between hot and cold supply on basin mixer taps.

Rated 5 out of 5Â by Southcoastboy Does the job, reasonable price
Used in a central heating system to stop a back flow around boiler piping.
Works fine, easy to fit took ten minutes, with a lot more time draining and refilling the system. For which I can't blame the fitting !
As for reliability 48 hours it's a bit hard to judge !
Strange question on something you have just fitted.

Rated 4 out of 5Â by Serialdiyman One minor quibble
OK solid check valves, but the rather small flat areas on the barrel sides are not the best I have used for getting a grip on with a spanner or wrench when tightening the compression joints. Aok once fitted.
