My Mira Excel shower (15 years old) has a leak. It is a concealed installation on a partitioned stud wall. Water is getting behind the back plate and/or in behind the control knobs and running down the stud wall behind the tiles. This must have been happening for some time now as I can see that the plaster board the tiles are attached to have actually eroded quite a bit.
The leak only seems to happen when water is hitting the tiled shower wall around the controls so am confident it is not the water feeds that are leaking.
I have dismantled to the back plate and control knobs and can't see anything that is obviously wrong. The concealing plate has a round foam seal which looks to be in good condition. The back plate is screwed through to the control unit and has been siliconed around the perimeter and this still looks to be in reasonable condition.
If someone uses the shower and makes the wall with the back plate/control knob fairly wet, I usually catch about half a tea cup full of water under the tray from behind the stud wall. If we avoid getting this wall wet, no water is collected.
If the foam seal is not to blame for the leak, does anyone have any other as to what could cause the leak?
I have attached some photos for clarification.
Thanks
