This question is regarding Aqualisa Multipoint Pink Combi Boiler Cartridge with Gasket - 022802

Very hot or very cokd

Hi. My Aqualisa valve is about 10 years old now and it’s becoming v difficult to get a suitable mixed flow. Move the temp control a millimetre to the left and the flow is icy cold. Move a millimetre to the right of centre and the flow is v hot water. Does this mean that the item needs replacing?

Regarding the temperature fluctuation or cool running, it could be a faulty cartridge. However to check this if you have the shower fed from a combi boiler, see if you can get hold of the hot supply pipe before it enters the shower or perhaps as it leaves the boiler.


If when holding this pipe the temperature fluctuates or goes cool, then the problem is not with the shower but more likely with the boiler, as the shower can only deliver what the boiler sends to it.

Disregard the temperature at the taps as they have a different flow rate.
