Thermostatic Mixing Valves are essential components in hot water systems for controlling the temperature of water. These valves provide safe and consistent hot water by blending hot and cold water together to reach the desired temperature.TMV servicing is essential to ensure that these valves work efficiently and maintain their effectiveness. In this article, we will discuss everything you need to know about TMV servicing.
What is TMV Servicing?
TMV servicing refers to the regular maintenance of thermostatic mixing valves. During servicing, the valve is tested to ensure that the valves’ components are working correctly and operating at a safe temperature.
Why is TMV Servicing Necessary?
TMV servicing is essential for three reasons:
1. Safety - TMVs are designed to prevent scalding by regulating the temperature of hot water. If the valve is not working correctly, the hot water may become too hot, causing burns or scalds.
2. Efficiency - A properly maintained TMV will work more efficiently, ensuring that hot water is delivered at the correct temperature, which will save energy and water.
3. Legionella Control – Strainers are installed to TMVs to reduce the risk of scale and other debris clogging the internal moving parts and non-return valves. These should also be cleaned to ensure that legionella bacteria growth is minimized.
How often should TMV Servicing be Carried Out?
The frequency of TMV servicing will depend on the manufacturer's recommendations, water quality, and usage. It is recommended that TMVs are serviced annually, but more frequent servicing may be required in high-usage areas or areas with hard water. This frequency can also increase in healthcare settings.
What is Involved in TMV Servicing?
TMV servicing involves the following:
1. Temperature check – check the input temperatures are acceptable for the valve to function and check the output temperatures are adequate for the outlet they supply
2. Failsafe / shut off test – when the supply to either the hot or cold water is shut off the valve should respond by shutting off the other, stopping the water flow
3. Remedial action – repair / replace faulty components or the valve itself depending on the defect
4. Clean the strainers/filters – gain access to the filters, carry out cleaning & de-scaling
TMV servicing is essential for maintaining safe and efficient hot water systems. If you have not had your TMV serviced recently, it is essential to arrange a service with a professional plumber. Regular TMV servicing will ensure that your hot water system remains safe and efficient, reducing the risk of scalding and helping to, minimize the risk of legionnaires’ disease.
