This question is regarding Aqualisa Midas 200/300 HP Thermostatic Cartridge with Knob (Chrome) - 518113

Buy high or low pressure cartridge.

When my Aqualisa Midas 200 shower was fitted, we had a ordinary boiler. We now have a combi boiler. Do I order the high pressure cartridge or the low pressure cartridge. Originally we had a pump but when we had the new boiler, the plumber removed the pump from the system.

If the cartridge you have is working OK then stick with it until it fails then replace it with the HP / combi cartridge.
