I've had 2 of the plastic stopcocks fail. I'm using them on exposed MDPE pipe whilst I build my extension, so they are in a dusty environment. One for the current house supply and one tee'd off for site water with a hose on the end of it. They have both failed to turn the water off when done up tight after on-off cycle maybe 20 or so times. One was from Wickes, other was philmac. All I can think is they are hopeless against ingress of dust. The Wickes one failed a day after some heavy dry cutting of concrete. A hoselock tap connector was under full mains pressure due to the stopcock failing, and had eventually popped off the end of the MDPE and the garden was being flooded. I guess it would have popped off when taps were turned off this morning and the static pressure had built up suddenly. I think I'll have to fit a copper one instead. Simon.
