- I isolated the water (it has one of these valves - or very similar: http://www.screwfix.com/p/15mm-isolating-valve-pack-of-2/65251 on the copper pipe feeding the shower) - turned off the power (wall and consumer unit) - waited a few hours, and then opened it.
Unfortunately despite turning everything back on the leak has stopped completely and I couldn't locate its source. I didn't like the idea of replacing parts inside the shower, and considering that a new one is only ~£50, I thought that I would simply replace it. I closed the shower cover, and left everything turned on. I haven't had the time to do anything about it for the next 3 days, when all of a sudden the leak returned (yesterday). I now turned the power and water off again.
We are going away very soon, and I was wondering how safe it would be to leave it like this.
The power is turned off both on the wall and on the consumer unit, so I assume that would be Ok?
But what about the water? Can these valves be used to shut the water supply to the shower for a few weeks?
