Its watermain in factory, they have got to take up the concrete slab so i can move it back and then re concrete over it, dont fancy burying a stopcock under the ground that cant be accessed.cant you bend it over which effectively squeezes it off. cut a stop valve in after the kink, unfold the pipe and voila you can work at your leisure with an isolated supply.
i think ill just get one of those compression clamp things and bill them for it
