Our upstairs ensuite electric shower died a few days ago and needs replacing, which appears an easy enough job apart from I can't figure how to stop water flowing from the inlet pipe when I disconnect the old shower. There isn't an isolating valve in the water pipe and turning off the stopcock under the kitchen sink doesn't stop the flow of water to the shower. So if I remove the old shower I'm going to have water flowing freely from the copper pipe which I presume is connected directly to the mains.
However I've noticed that some showers can be gravity fed from the cold water storage tank in the attic, I presume i can check this by closing the stopcock under in the kitchen (does this turn off all mains water?), and then empty the tank by running the cold taps in the bathroom. If the shower is fed from here then the flow should stop. However will this effect our typical gas fired central heating at all?
Or do I just remove the shower and try and fit an isolating valve onto the flowing pipe?
Advice much appreciated!
