Rated 4 out of 5Â by GreenStuff Full Bore 22mm isolating valve
If you have a gravity fed shower, where the water pressure isn't great, then fitting these valves are essential to ensure that the shower water flow isn't reduced.

Product is great and works as it should. Biggest disappointment was only one in stock ! This items is more commonly required in pairs and to find one in stock meant a second trip to another store. Common sense...minimum stock level 2 !!!

I bought a pair of these valves to replace a couple of standard isolation valves after finding out that one wasn't shutting off at all and the other one was letting by.
When I went to fit them I thought it would be a lot more straight forward than what it was by just taking out the old valve, use the existing nut and olive and just replace the body, but found that the collar depth is shorter than that on what I would call a conventional run of the mill solation valve, so be prepared in having to remove the old olive and nut if you're replacing an existing valve.
Once fitted they seal really well even under pressure of the combi boilers hot water supply and with the full bore opening improves the flow of water through the tap.
On the whole the valve has an excellent build quality, install is fairly straight forward and will definitely convert to using full bore valves in the future.

Fitted for 6 weeks now and seized so tight that the cross slots burred off when I tried to close them. The cross slots aren't very deep, but they are wide (you'll struggle to find a screwdriver blade thick enough to fill the slot#. I used a thick steel washer holding that with mole grips to shift them #both of them). The metal slot top screw head is so soft, it's next to useless. I'll try to cut deeper slots in the heads, but failing that - mole grips are the only way to turn them on / off. Very disappointed indeed - not the sort of quality level I'd expect from Screwfix ! Avoid them.
