Hi, I am replacing my old electric shower, there is no isolation valve currently present so i want to add one. To install the new electric shower i will have to change the pipework and move the electric supply cable (chopping out tiles and plaster etc). I was thinking that i could use a flexihose (15mm compression at each end) with incorporated service valve to do the same job. I have used them for hot and cold water fittings for taps and standad showers but wondered if they were suitable for use for the cold water feed for electric showers? Would the job much simpler Thanks
