What is a Thermostatic Mixing Valve (TMV) and Why is Testing Important?

Thermostatic Mixing Valve Testing | Geelong | Torquay | Ocean Grove | Clifton Springs | Drysdale | Tomlinson Plumbing

A Thermostatic Mixing Valve (TMV) is a vital plumbing device designed to regulate water temperature, blending hot and cold water to prevent scalding.

These valves are commonly installed in aged care facilities, day care centres, hospitals, schools and other facilities where safe water temperatures are essential.

TMVs protect against burns and scalds, particularly for children, the elderly, and other vulnerable individuals.

By keeping water at a consistent, safe temperature, TMVs also reduce the risk of bacteria growth, such as Legionella, in hot water systems.

Even the best TMVs can degrade over time. Regular testing ensures:

·      Water temperature remains safe.

·      The valve operates correctly under changing water pressures.

·      Compliance with Australian standards (AS/NZS 3500).

·      Early detection of wear or faults before they become costly or dangerous.

Regular TMV testing is not just a legal requirement in many commercial and public settings; it’s a critical safety measure. Scheduling routine testing with a qualified plumber protects people, reduces liability, and keeps your water system working efficiently.
