Thermostatic mixing valves’ or TMVs’ plumbing maintenance and testing are essential to maintaining a safe and consistent water temperature. TMV failures and faults can pose a serious risk to occupants and workers inside businesses and medical or public facilities.

We perform a thorough inspection and cleaning to ensure the proper functioning of your TMV device. This gives you the security and peace of mind that your workplace is safe from potential accidents and hot water hazards.


TMVs are typically installed near hot water systems or distribution sources to regulate the temperature of the water. They help mix the hot and cold water to prevent hot water injuries like scalding and burns. Thermostatic valves are installed in commercial and industrial properties and social and healthcare facilities like schools and hospitals. They can even be installed in residential properties if homeowners require it. If there is a problem with the hot or cold water supply, the mixing valves shut down the water automatically, protecting the user.

TMVs are a mandatory requirement in most businesses and facilities and must be tested and serviced annually. The maintenance and testing services must meet industry and legal regulations. Thermostatic valves are a critical safety component to ensure a safe, even hot water temperature.
