Great looking in a modern and designer shower, or bath with only controles exposed for an automatic temperature adjustment.
These automatic mixer valves suffer from limescale problems which stop them working properly. The only option is to replace the internal cartridge which is known as a thermostatic cartridge valve. An expensive part which makes his system be so versatile and pleasant to use.
This repair doesn’t require any tiles or wall damage which is an additional advantage when expensive and rare tiles are used and hard to find a spare one.
In very rare cases , unfortunately there is no other solution other than replacing the shower mixer valve completely if spare parts are out of production.
Requires 2 visits and a fixed price will be agreed on assessment which will include part cost and labour in order to repair the mixer.
