Title: Electric Shower
Post by spongebob on Jun 22^nd, 2005, 11:35pm

I'm about to install an electric shower (No,not doing the electrics). The plan is to conceal the supply pipe work in the stud wall. Using this method prevents the use of a seperate isolation valve for this appliance. Am I likely to fall foul of any regs?

yeah, cant you put the iso valve in the loft or under the bath, depending on how you are running the pipework. I imagine you are teeing into the main cold water supply somewhere, putting the valve in there would do, if its accessible(you know where it is)

Thanks for the reply. All pipework is going to be concealed behind tiles or boxing in. Work is to be inspected so want to get things right. Will have to think about this.

Pipework re-designed and iso valve installed where it can be accessed by removeable section of boxing in. Before I proceed any further should I be considering a single check valve. The shower head will be above a tray and is not likely to be immersed in water. I'm concerned about the likelihood of the flow being affected if I install a check valve.

if the shower head cannot be immersed in water you dont need a check valve, however, if you later install a longer hose it might be, and if you are running from the mains the check valve wont restrict the flow too much, in fact i fitted a mixer shower today which came with check valves on both hot and cold(gravity) and the flow restriction was negligible.

Flippety flip!! Will put check valve in to ease potential of guilt at later date.
