"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)"
"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!"
"I am consistently impressed by these copper push-fit fittings. They really lower the bar to entry for a DIYer and are so much easier to use than compression or soldered fittings, especially where space is tight. I got this valve into a ridiculously tight space where replacing the pipe to get more length to work with would have meant tearing out a kitchen wall. Heat was not an option and there was absolutely no chance of getting spanners in there for compression. I have had zero failures to date, not a single drip, from any of these copper push fit fittings I've put in.
My tip - in case of emergency while working on your plumbing, always keep a push-fit end stop in your pocket, preferably a plastic one so it's easy to remove again.
They can be a touch expensive but always far cheaper than a plumber."
"These pushfit fittings are great for anyone attempting small plumbing jobs, ie replacing a bath or repairing pipework. Much more solid than its plastic rival, measure, cut, and fit, its that simple. If your a competent diyer then you can save money buying soldered fittings but these pushfit fittings are so hassle free I think its worth the extra. whatever way it will work out cheaper than a plumber!"
"These are great fittings, although the price has gone up alot and i would not recomend them for plastic pipe. To remove the fittings you need a tool and this is fine on copper but when removing plastic i have found that the pipe insert gets stuck and cannot be removed without damaging the 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."
"I found these horrible to fit to my existing pipework. I don't consider myself weak for a female yet I didn't have the strength to push these fittings home properly, even on beautifully cleaned and prepared pipe. In the end I had to thwack them pretty hard with my adjustable spanner to achieve a leak free fit. Having recently installed a couple of compression fittings and a JG Speedfit I can say that this pushfit is EASILY the least fun I've had with plumbing lately.
That said, once I finally got them on, they do appear to be sound so I won't give them the lowest marks. And obviously they have advantages where space is limited for wielding tools...but it's Speedfit from now on for me!"
