Hello
I am fitting an electric shower onto a stud wall, with suitable reinforcement. An electrician will make the final connection and certify it.
I expected the shower (Mira Go) to be sealed against the wall, but this you must not do - the shower is designed to have space at the rear for ventilation. I want the electrics and plumbing to come into the rear entry, obviously through a hole in the wall.
My question is, given that water can trickle down the gap at the back of the shower, then onto the pipe and cable, what should I do a) about protecting the pipe and cable from the edges of the tiles and b) sealing them. I can see that making a hole which is only slightly larger than required and putting sealing compound around is possible, and should be okay since there is not going to be any movement, but I am aware that elsewhere cable entering a metal box has to be protected by grommets even though there again there is no movement. One solution to this would be to feed them through hosepipes, but this seems a little DIY/Heath Robinson.
I can't find any information concerning this in the installation instructions that came with the shower, nor can I find it mentioned anywhere on the web including here. Yet it is something that many installers will face?
