SUMMARY

Ideal Standard A963855NU Trevi Boost Venturi Thermostatic Cartridge for A5699AA A5700AA and A5701AA Shower Valves

Ideal Standard A963855NU is a Trevi Boost Venturi thermostatic cartridge used for temperature control in selected Trevi Boost shower mixer valves. Ideal Standard documentation describes the part as the New Trevi Boost Venturi Cartridge and as a Boost cartridge venturi.

The cartridge regulates the mixing of hot and cold water inside the Trevi Boost valve to control the shower outlet temperature. Restricted flow can be caused by blocked cartridge filters or a non-return valve fault, while water remaining excessively hot can indicate a restricted cold supply or a seized cartridge.
