What it is

The Aqualisa 265509 is a thermostatic cartridge for Aqualisa shower valves, supplied in the gravity variant and identified by an orange marking on the cartridge body. It regulates the mix of hot and cold water to hold a stable outlet temperature at the shower head. The cartridge sits inside the valve body and is the component that responds to changes in supply temperature and pressure.

Before you order

  • Confirm the cartridge removed from the valve carries the same orange identification marking, as Aqualisa thermostatic cartridges are supplied in variants that are not interchangeable.
  • Check the valve is fed from a gravity (tank-fed) hot and cold supply, which is what this variant is intended for.
  • Verify the part number 265509 against the valve documentation or the marking on the existing cartridge before ordering.
  • Check the valve body and seals for damage or scale while the cartridge is out, as debris in the body can affect the performance of a new cartridge.
