question for our plumbers

[kilty55]

hi all,i have a nice bathroom to begin next week,my customer has changed there mind at the last minute and has emailed the shower change they want

my plumber is away for the weekend so cant get his advice.....

we were to instal a standard mira power shower and they now want a digital controlled power shower

is there any difference in these for installation.....its a gravity fed system so i know its compatible that way but its saying it has an extaernal controller the size of a shoe box i assume this is the pump ?

do we need any different installation specs for these digi showers?

cheers for any advice

you need balanced gravity feeds of hot and cold to the digital valve.

cold from the cold water cistern on a separate draw off to the hot water cylinder feed at the oposite end to the ball **** to avoid air in the water

the hot can come off the expansion but is better off a essex or s flange.

a feed from the valve to the wall outlet point for the blended water and the control cable from the valve to the control point.

a switched electrical feed to the valve that must be off the ring main not the lighting and be protected by an rcd

hope this helps
