we've got an Aqualisa Quartz shower (with the controller / mixer unit in the loftspace above the shower). Very pleased with it until recently, it's starting to drip from the shower head even when the unit is off - not a lot but enough to keep the bottom of the bath wet and then beinjg a hard water it scales up.
Any idea what to do? Anyone have any knowledge of these and whether this is an age thing? It's about 8 years old. Is it possible to renew valves and things in the box without renewing the whole thing?
