We have a built-in shower (Mira) with a control dial and a shower head. Recently we have noticed that water is leaking from the control dial. It appears to be the hot water feed as it is much hotter than the water from the shower head. There does not appear to be any leakage behind the tiles as I can see under the shower tray - now water there, and no water through into the downstairs as yet.
Any ideas?
