FAQs
What is TMV3 approval?
TMV3 approval is a UK standard for thermostatic mixing valves, ensuring they meet strict performance and safety requirements for use in healthcare premises.
Does this valve control the water flow?
No, this mixing valve controls the temperature only. It must be used with a separate outlet flow control, such as a tap or shower valve, to regulate water flow.
How often does the Radatherm cartridge need servicing?
The Radatherm cartridge is designed to be service-free, meaning it does not require routine maintenance or replacement under normal operating conditions.
Can this valve be used in a domestic setting?
While it can be used in domestic settings, its TMV3 approval and design are optimized for the stringent safety requirements of healthcare environments.
What is the purpose of the check valves and strainers?
Check valves prevent backflow of water, and strainers filter out debris from the water supply, protecting the valve and ensuring optimal performance and longevity.
Can the inlet elbows be rotated?
Yes, the inlet elbows are adjustable, allowing for flexibility in positioning during installation to suit different pipework configurations.
What is the recommended installation location?
The valve is suitable for duct mounting, under-basin mounting, or within a cupboard, provided it allows for necessary access for any future strainer cleaning.
Troubleshooting
Water temperature is inconsistent.
Check that the hot and cold water supplies are adequate and stable. Ensure strainers are clean and not blocked. Verify that the mixing valve is correctly installed and that the outlet flow control is functioning properly.
Low water flow from the outlet.
Inspect and clean the strainers located at the valve inlets. Check for any kinks or blockages in the pipework leading to the outlet. Ensure the outlet flow control is not restricting the flow excessively.
Valve is leaking.
Ensure all connections are securely tightened. Check the condition of any seals or washers. If the leak persists, the valve may require servicing or replacement.
Difficulty adjusting temperature.
Ensure the valve is not suffering from low supply pressures. Verify that no other devices are significantly altering the hot or cold water supply while attempting to adjust. If the issue persists, contact a qualified plumber.

Setup, Compatibility & Care Instructions
Setup:
- Ensure the water supply is turned off before beginning installation.
- Mount the valve in the desired location (duct, cupboard, or under-basin), ensuring it is securely fixed.
- Connect the hot and cold water inlets using the adjustable elbows, tightening securely.
- Connect a separate outlet flow control (such as a tap) to the valve's outlet.
