The Essential Guide to TMV Servicing: How Often Should You Schedule Maintenance?

Within water systems, thermostatic mixing valves (TMVs) take centre stage, ensuring the safe and consistent delivery of water at a desired temperature. To guarantee the reliability and effectiveness of these crucial components, regular TMV servicing is paramount. In this article, we'll explore the significance of TMV servicing and answer the vital question: how often should you schedule maintenance for your thermostatic mixing valve?

The Role Of TMV's In Water Safety

Before delving into the servicing frequency, let's briefly revisit the role that TMVs play in water systems. TMVs are engineered to blend hot and cold water to maintain a safe and controlled temperature at outlets like showers and faucets. Their primary objectives are twofold: prevent scalding by regulating water temperature and enhance user safety by maintaining a consistent and comfortable water flow.

Why Is TMV Servicing Important?

  1. Safety Assurance: The top priority when it comes to TMVs is user safety. Regular servicing ensures that these valves are functioning optimally, preventing the risk of scalding accidents caused by water temperatures exceeding safe limits.

  2. Legal Compliance: Adhering to safety regulations is not just a good practice – it's often a legal requirement. Routine TMV servicing is crucial to ensure compliance with local regulations and standards, shielding both Estate Managers and occupants from potential legal ramifications.

  3. Longevity and Reliability: Similar to any mechanical device, TMVs undergo wear and tear over time. Routine servicing identifies and addresses issues promptly, extending the lifespan of the valve and enhancing its overall reliability.

How Often Should TMV's Be Serviced?

The optimal frequency for TMV servicing depends on several factors:

  1. Annual Inspection: As a general rule of thumb, schedule a comprehensive TMV inspection at least once a year. Engage one of our technicians to assess the valve's condition, test its performance and identify any potential problems.

  2. Water Quality Considerations: The quality of water in your system can impact TMV performance. If your water supply is prone to issues like sedimentation or scale build-up, then consider more frequent servicing to prevent these factors from affecting the valve's functionality.

  3. Usage Patterns: High-usage environments, such as commercial spaces or healthcare facilities, may require more frequent TMV servicing due to increased wear from constant use.

  4. Manufacturer Recommendations: Always consult the manufacturer's guidelines for your specific TMV model. They often provide specific recommendations for servicing intervals and maintenance procedures tailored to the valve's design and materials.
