This cartridge, as with all thermostatic cartridges will need replacing over time. Depending upon the area in which you live and the type of water running through the cartridge, that is, how much limescale is in the water, will determine how often the cartridge needs replacing.

Limescale not only builds up in the cartridge but also wears away the cartridge as the moving parts rub against the the hard build up.

What are the symptoms of a cartridge which needs replacing?
- Water is leaking / dripping through the thermostatic valve
- Water temperature isn't regulating correctly (this could be either too hot, too cold, or fluxing up and down).
- The temperature control handle will begin to stiffen. This is because the inside of the cartridge starts to seize up.
