Sometimes showers can go faulty, if they can be identified its generally no issue. The manufacturers can be contacted and parts obtained. As easy as that.
But, when the shower can not be identified, that is when the problems start. Especially with concealed shower valves. The repair evolves into a replacement which usually involves a degree of re tiling.
Luckily this customer had spare tiles. We cut out two tiles to expose the valve, altered the pipework to suit new shower and re tiled. The shower installed was a new Mira rain head shower. This shower valve has standard fixing coming out of the tiles so if ever the shower is to be replaced in the future the process is much simpler. Also we now know the make and model of the shower.
TIP: If you have a concealed shower valve and you know the make / model. Write it down somewhere safe as that info could come in very handy and save you £££.
