Grey cartridge issue
Yes the blue cartridge is discontinued now and Aqualisa do say you replace it with the Grey. The suggest that if the shower has been fitted on a combi boiler for some time then a grey cartridge will work ok. We have found cases where the pink was needed afterwards. It seems strange that you had a blue manual cartridge fitted which is not thermostatic.
Have you had a combi boiler or high pressure system fitted recently?
