Our Comprehensive TMV Servicing Process
At PTS, we follow a meticulous TMV servicing process to ensure optimal performance. For us, at PTS, compliance with industry standards is an important part of our process.
- Visual Inspection: Our technicians thoroughly inspect each TMV, verifying the correct valve specification, accessibility, and the presence of isolation valves.
- Temperature Monitoring: We measure and record the mixed water temperature to ensure it falls within the recommended range of 39°C to 43°C.
- Failsafe Testing: Our team conducts failsafe shut-off tests by simulating cold water supply failure, confirming the TMV's ability to shut off the hot water supply.
- Cleaning and Disinfection: We isolate each TMV, clean and descale valve components, and disinfect fine mesh strainers to maintain water quality standards.
- Record-Keeping: Detailed records of all inspections, maintenance activities, and servicing details are meticulously documented for future reference and regulatory compliance.
The Importance of Regular TMV Servicing
Precision mechanical valves called TMVs regulate water temperatures, keeping them within a safe range. Typically between 39°C and 43°C. However, various factors can compromise these valves over time. Factors such as; scale build-up, worn components, or changes in water supply conditions. Failure to service TMVs regularly can lead to potential safety hazards like scalding incidents or exposure to Legionella bacteria.
Expertise in TMV Specification and Compliance
Pipe Testing Services has extensive expertise in TMV specification and compliance requirements. We understand the nuances of the Care Standards Act 2000, NHS Model Engineering Specification D08, and NHS Estates TMV3 performance standards. The NHS Estates TMV3 performance standards are requirements for thermostatic mixing valves (TMVs). Used in healthcare and social care settings to protect vulnerable users, such as children, the elderly, and disabled persons, from the risk of scalding from hot water.
Our team ensures that the correct TMV specifications are installed in appropriate locations, meeting regulatory standards and providing optimal thermostatic protection.
TMV3 Performance Standards
- TMV3 valves must undergo regular in-service testing to ensure they are performing correctly and delivering safe mixed water temperatures between 39°C and 43°C.1
- If a TMV3 valve fails an in-service test, it must either be serviced according to the manufacturer's instructions or replaced if it cannot be serviced.
- The servicing and maintenance of TMV3 valves should follow the guidance provided in the NHS Model, with further testing carried out 12-15 weeks after servicing.
- Regular ongoing in-service testing is essential to demonstrate the TMV3 valve is maintaining adequate thermal performance.
- If the outlet temperature has increased by more than 2°C or the failsafe does not work, the TMV3 valve requires a full service and recommissioning, or replacement.
- Proper management of the risks associated with scalding from hot water in healthcare and social care settings is a critical safety requirement that is addressed through regular TMV3 testing and servicing.
FAQs (TMV Servicing & Maintenance)
How often should TMVs be serviced?
TMVs should undergo regular servicing and maintenance to ensure their proper functioning. The frequency depends on various factors, such as the usage, water quality, and manufacturer’s recommendations. Generally, TMVs should be serviced at least annually, or more frequently in high-risk or high-traffic areas.
What are the consequences of not servicing TMVs regularly?
Neglecting regular TMV servicing can lead to potential safety hazards, including scalding incidents, exposure to Legionella bacteria, and non-compliance with regulations. Poorly maintained TMVs may fail to regulate water temperatures accurately or fail to shut off the hot water supply in case of supply failures.
Can TMV servicing be carried out on-site?
Yes, our experienced technicians can perform TMV servicing on-site, minimising disruptions to your facility’s operations. We work closely with your team to schedule servicing at convenient times and ensure minimal downtime.
What records are maintained during TMV servicing?
Our team maintains detailed records of all inspections, maintenance activities, and servicing details for each TMV. These records are essential for demonstrating regulatory compliance and facilitating future servicing and maintenance activities.
Can TMVs be repaired or do they need to be replaced?
In some cases, TMVs can be repaired or serviced to restore their functionality. However, if the valve is severely damaged or cannot be serviced according to the manufacturer’s instructions, replacement may be necessary. Our experts can assess the condition of your TMVs and recommend the appropriate course of action.
