How to Service a TMV

Servicing a Thermostatic Mixing Valve (TMV) is essential for maintaining safe and reliable hot water systems. At TMV Servicing Company in Leith, we provide full TMV servicing to ensure compliance, performance, and protection against scalding and Legionella risks.

1. Isolate and Inspect the Valve – We begin by isolating the water supply and dismantling the TMV for inspection. Our engineers check for scale buildup, debris, or worn components that may affect temperature control.
2. Clean and Descale Components – Each component is thoroughly cleaned and descaled to remove mineral deposits and bacteria. This restores smooth operation and prevents temperature drift.
3. Check and Replace Parts – We inspect the thermostatic cartridge, filters, seals, and strainers. Any worn or damaged parts are replaced with manufacturer-approved components to guarantee reliability.
4. Reassemble and Test Performance – After reassembly, we restore the water supply and test the valve’s response and accuracy. Using calibrated thermometers, we confirm outlet temperatures remain within the safe range of 41–44°C.
5. Record and Certify Compliance – All readings, findings, and replacements are logged in a TMV service report for compliance with HSE and Building Regulations.

We offer scheduled TMV servicing across healthcare, education, commercial, and residential sectors. Our qualified engineers ensure your systems stay safe, compliant, and efficient. Contact our team today to arrange professional TMV servicing in EH6 7.

How Often Should a TMV be Serviced?

It is recommended to service TMV’s in Leith every 6-12 months.

The frequency of TMV servicing in Leith largely depends on the specific compliance and safety requirements of the facility.

One crucial factor determining the servicing frequency of TMVs is the usage intensity in the building. High-traffic areas such as hospitals or gyms may require more frequent checks compared to residential buildings.

The age of the TMV system plays a significant role. Older systems may need more frequent servicing to ensure optimal performance and prevent potential failures.

Adhering to a regular servicing schedule is essential to maintain the efficiency and longevity of TMVs. Neglecting maintenance can lead to issues such as temperature fluctuations, reduced water flow, or even complete system failure.

What are the Requirements for Thermostatic Mixing Valve?

Thermostatic Mixing Valves are required to control hot water temperatures and prevent scalding. UK legislation, including the Building Regulations Part G and Health and Safety Executive (HSE) guidance, sets clear requirements for their installation, performance, and maintenance.

• Temperature Control – TMVs must blend hot and cold water to a safe, stable temperature before it reaches the outlet. The maximum recommended outlet temperature is 41°C for showers and wash basins and 44°C for baths in healthcare and residential care settings. These limits prevent scalding while maintaining hygiene standards.
• Installation Standards – All TMVs must comply with BS EN 1111 or BS EN 1287 standards, depending on operating pressure. Installation must follow manufacturer instructions and include accessible isolation valves and strainers for maintenance.
• Compliance in Specific Settings – TMVs are mandatory in hospitals and healthcare premises (as per HTM 04-01), schools, nurseries, care homes, new-build domestic properties and major refurbishments. These environments require TMVs at all baths, showers, and hand wash basins used by vulnerable persons.
• Regular Servicing and Testing – TMVs must be serviced every 6 to 12 months to ensure accurate temperature regulation and prevent bacterial growth, especially Legionella. Servicing includes cleaning, descaling, and performance testing under live conditions.
• Documentation and Certification – Each service must include a recorded temperature test, valve condition report, and compliance certificate. This ensures traceability and proof of safety compliance for audits and inspections.

At TMV Servicing Company, we install, test, and service TMVs in full compliance with UK safety and health regulations. Our certified engineers ensure every system meets the required standards for performance and protection.
