If after a period of time you experience temperature problems with your shower valve,
particularly if you are in a hard water area, it is quite common for limescale deposits to have formed
in the thermostatic cartridge. We recommend you remove the cartridge and soak it in a descaling fluid
which normally resolves the problem. It is difficult to set a regular servicing time scale as it is subject to
water conditions and usage.
