I have a faulty stopcock in my flat (gate valve that doesnt stop the water) and I wanted to replace it without shutting off the water in the street as this would affect other flats.
The water supply feed is 15mm plastic pipe which comes out of the floor about 6 inches before terminating into the gate valve.
I saw this clamp type tool http://www.toolstation.com/shop/Hand+Tools/Plumbers+Tools/Squeeze+Off+Tool/d10/sd210/p39855
Would that be suitable to shut off mains pressure, and more importantly, not damage the pipe?
