Perfect!
This little thing is being used befor the booster pump on the main water inlet. The reason is to dont let the water to flow back and stoping the booster pump to switching on every so often for a short term to build the pressure up in the pipes. If there is no NRV in your system then the water can flow back and because the pump pressure sensor feels the pressure drop it will switches on for a short term to get the set pressure in your pipe system, even if you never opened a tap. So this is esential for booster pumps!!!!

Poor nuts
The valve is reasonably short, and seems to work well. However, the compression nuts are strange. They are 25mm A/F and have very rounded corners leaving little "flat" for a spanner to lock onto. I was very uneasy about using them so I used a pair of normal sized nuts from a redundant compression joint instead.

Good to deal with

Effective, but the flow it allows varies from one sample to another.
These work, but of the three I bought, two required considerably higher pressure to open than the one I ended up using, on a fairly low pressure hot water supply. Also, the nuts and the flat on the body of the unit could be easier to manipulate with a spanners, which tend to slip off rather easily. But it has done the job.

Nuts are rubbish - not enough ‘flat’ to grip properly
As another poster said - the nuts on these are useless. The actual fitting seems ok and the valve works. I too replaced the nuts with some I had in my toolbox. I would pay another couple of quid next time and get a better one.
