"This valve has little to no flow restriction compared to cheaper versions. Bought both 15 and 22 MM versions. So both bath and basin fills should be quick. Construction looks good and solid. Isolate operation is quite tight so seal looks to be good."
"Great value product. At this price you can fit them liberally and avoid problems down the line. It's far easier to isolate something than drain the system to change it. An essential for the plumbing toolbox."
"I always fit an isolation valve to electric showers and every piece of pipework at - say sinks and cisterns - because it saves a lot of time by not having to locate the stopcock and partially draining the system. NOTE these valves are for use on water pipes only. Gas isolation valves are plentiful but do not be tempted to fit them if you are not in the trade, get a plumber, expensive but essential for safety !!!"
"Just not possible to get better value for money these should be bought as these save so much time when replacing water taps etc when you can isolate water supply easily a must have product will last a life time."
