Summary
Ultramix Trubert Eurotherm TX3 Thermostatic Cartridge (TX93E, TX93C, T/X93CHP, 10047813) - Flow Rate (Litres Per Minute): Minimum 3 - Maximum 120L
The Watts Industries ET-TX3 Ultramix TX3 thermostatic cartridge is a replacement thermostatic mechanism for Trubert Eurotherm Ultramix TX93 high productivity thermostatic mixing valves in the 10/50C temperature range. The cartridge is associated with Watts reference 22TX3 and Di Vapor listing code 10047813.
It regulates the mixed outlet temperature inside the valve, helping restore stable thermostatic control where the existing TX3 mechanism is worn, scaled or no longer holding temperature correctly. Check the valve marking before ordering because the 30/70C TX93E37 and TX93C37 version uses TX337 rather than TX3.

Installation and Pre-Order Checks
- Confirm the existing valve marking before ordering: TX93E, TX93C or T/X93CHP for the 10/50C TX3 cartridge.
- Do not order ET-TX3 for TX93E37 or TX93C37 30/70C valves because those use the TX337 cartridge.
- Isolate the hot and cold water supplies before removing the old mechanism.
- Clean the valve body and apply silicone grease to the cartridge O-rings before fitting.
- Recommission and check the mixed water temperature after replacement.
Troubleshooting
- Symptom: mixed water temperature fluctuates or will not reach the set point.
- Likely Cause: the thermostatic cartridge may be scaled worn or blocked.
- Solution: check inlet filters valve marking and water supplies then replace the cartridge if the TX93 10/50C specification is confirmed.
