At TMV Servicing, we specialise in the maintenance, testing, and repair of Thermostatic Mixing Valves (TMVs) to ensure safe and efficient water temperature regulation.

TMVs play a crucial role in preventing scalding, reducing Legionella risks, and maintaining compliance with water safety regulations in healthcare, educational, commercial, and residential buildings.

Regular Thermostatic Mixing Valve servicing helps extend the lifespan of TMVs, improve performance, and prevent costly system failures.

If you’re looking for professional TMV servicing, our certified engineers are ready to assist.

Why is TMV Servicing Important?

Regular TMV servicing is critical for preventing water temperature fluctuations that can cause scalding injuries.

Compliance with health and safety regulations is required in hospitals, care facilities, schools, and commercial buildings, where water temperatures must be strictly controlled.

Thermostatic Mixing Valve servicing also helps prolong the lifespan of TMVs, preventing blockages, wear, and unexpected failures that can lead to costly repairs or replacements.

How much does TMV Servicing Cost?

The average cost of TMV servicing is £250 – £300.

The cost of thermostatic mixing valve maintenance depends on various factors such as system complexity, required services, location, and the chosen service provider.

What does TMV Servicing Include?

A professional TMV servicing includes the following steps to ensure optimal performance:

• Temperature testing – Verifies that the TMV maintains a safe and consistent water temperature.
• Shut-off test – Simulates a cold water supply failure to check response time and ensure proper shut-off in emergencies.
• Cleaning and descaling – Removes limescale buildup and debris that could obstruct the valve.
• Filter inspection and replacement – Ensures that clogged or worn-out filters do not impact water flow or temperature regulation.
• Flow rate testing – Checks water pressure and consistency to prevent fluctuations.
• Valve adjustment and calibration – Fine-tunes the TMV for optimal performance and longevity.
• Full condition assessment – Inspects for leaks, corrosion, or worn components that may require servicing or replacement.

How Often should TMVs be Serviced?

TMVs should be serviced every 6 months in high-risk environments such as hospitals, nursing homes, and schools, where temperature control is critical for safety.

In commercial properties, hotels, and gyms, annual servicing is generally sufficient to ensure consistent water temperature regulation.

Residential properties with TMVs in bathrooms or kitchens should also undergo periodic servicing, especially if there are signs of reduced performance or fluctuating water temperatures.

Who Needs TMV Servicing?

TMV servicing is a legal and safety requirement for facilities where water temperature control is crucial, including:

• Hospitals and care homes – Essential for preventing scalding and bacterial contamination in high-risk environments.
• Schools and nurseries – Protects children from sudden water temperature fluctuations.
• Hotels and gyms – Ensures compliance with water safety regulations in high-usage facilities.
• Commercial buildings – Maintains safe water systems in workplaces and public spaces.
• Residential properties – Keeps TMVs in kitchens and bathrooms functioning efficiently for safe temperature control.
