Rated 4 out of 5 by from Not bad ! Quality is not as I have seen in other valves, but it is fit for purpose. Flat sided body helps with fitting too

Rated 3 out of 5 by from Not good for low pressure hot? Had no problems using these on mains cold, but I don't find them suitable where the requirement is in a gravity fed hot. In both cases I have tried this, the valve has seemed OK at first, but then within days, started sticking on first use of the day having been shut overnight. Leaving the tap on for maybe 10-20 seconds OR giving the body of the valve a light tap with a screwdriver - tends to release it, where it will usually work the rest of the day. So I ended up in both cases fitting a replacement from another manufacturer/supplier - and those have worked fine.

Rated 5 out of 5 by from Does what it's designed to do As with all screwfix brassware these valves are reasonable value and do what is expected of them. The most important thing is that they are available over the counter at a local store.

Rated 4 out of 5 by from works fine Valve was stuck when I got it (ie I could not blow through it) which might have caused a problem with low water pressure. But unstuck it first and it does the job fine.

Rated 4 out of 5 by from 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 5 by from 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 5 by from 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.
