Hi, any help appreciated. I have an Aqualisa thermo, mixer shower, about 5 years old, and for the last year or so it drips from the bottom of the plastic unit, this has recently got worse, I live in a hard water area in london, is it worth replacing washers and seals or is it cheaper to replace whole unit ??
thanks--Graham

The thermostat cartridge needs replacing. Look on net. Pay about £80. Easy to fit, but need to turn off mains water hot and cold first
