Rated 3 out of 5Â by ooo00ooo I'd go with JG isolator valve
Went for Cuprofit instead of JG on weight of reviews and because they look better. Now in my case I think this was a mistake. The Mira Shower I installed came with a couple of JG isolators for inlets but needed a couple more for outlets. The JG isolators were so much easier to fit and remove when needing to adjust the pipework to get right. The Cuprofit ones are really difficult to remove (I have the release tool) anyway, especially in situ. You also need a min amount space behind the fitting to allow the release tool to actually go on and to grip to push it off. In my case the Mira shower came with custom copper pipe outlets of predetermined length and once the cuprofit was on, there isn't enough space to use the tool.. so thats it. I will need to go to Mira to get replacement 15mm copper pipe.outlet when/if I need to change these. They were also really difficult to actually get on fully. The straight couplers and elbows were easier but these isolators seem to be much tighter for some reason.
They do look better and are shorter than JG speedfit, mantain earth bonding and I believe these can be used > 65deg unlike JG but for ease of use JG win I'm afraid and on balance I wish I had gone JG for these.
Once on though, I'm pretty sure they will stay on and wont leak so hope shower will stay where it is for some time so I don't need to change them.

Bought these to isolate radiator pipes under floor whilst bedroom was re plastered and as we needed to fit a longer radiator after having work done in bedroom we needed to replace and lengthen pipes to new bigger radiator These push fit Valves were easier to use than I thought Performed well when isolated and when I Connected new pipe work and opened valve hey presto warm radiator NO LEAKS and no more compression joints for me
Great Product for the DIY'r just push it on (firmly)

Rated 5 out of 5 perfect product
Purchased this for my husband who is disabled with arthritis and would now struggle to fit compression or soldered joints. He managed to do the job in no time at all and without causing him any pain. He is so impressed; he wants to know if Screwfix can supply him with some push fit knees and elbows that could be changed as fast!

Well made reliable fittings, probably the best on the market, not cheap but real quality.
