Frequently Asked Questions: Ideal Standard Trevi Boost A963348AA Thermostatic Cartridge
Q: Why is my shower is not running hot water after replacing the thermostatic cartridge?
A: Hot water flow might be blocked. To confirm, take the A963348AA cartridge out and switch on the flow valves.

A: Cartridges come calibrated by the manufacturer out of the box. The Ideal Standard A963348AA can be recalibrated if you prefer a different temperature.

Q: My shower is leaking. Do I have to change the cartridge?
A: A cracked cartridge or depleted o-rings might cause leakage. To check if the cartridge is the cause, please remove the cartridge to check for signs of damage. If there are damages or blockage, the cartridge needs to be replaced.

Q: Is this compatible with pressure balance showers?
A: The A963348AA cartridge is compatible with valves listed above. It would help if you send us a photo of the valve in question.

Q: I cannot pull the cartridge out of the shower unit.

Shower Facts: Thermostatic Mixer Valves (TMVs)
A water temperature regulating capsule is the core of a thermostatic mixer valve (TMV). The tiny capsule enclosed in a thermostatic cartridge is sensitive to fluctuations of water temperature. Hot and cold water is mixed by the cartridge to yield the right temperature as determined by the user. As a result, the water temperature can be maintained for the entire duration a user showers.

TMVs are compatible with the majority of home plumbing systems. The only exception are systems that are plagued with unstable water pressure. To address this, isolating or pressure equalizing valves can be installed to steady cabin water flow making the plumbing system feasible for TMVs.

Certified thermostatic mixer valves are built with a safety system that will shut water flow in the event of a drop in water pressure or water supply failure. The cartridges are commonly calibrated by the manufacturer to a lukewarm 38℃ or 100.4℉.
