Hot water safety is something every household and business should take seriously — especially when young children, elderly individuals, or vulnerable people are present. One of the most effective ways to prevent accidental burns or scalding is by installing a Thermostatic Mixing Valve (TMV). At Mad 4 It Plumbing, we provide expert installation, testing, and maintenance of thermostatic mixing valves across Penrith and greater Sydney. Whether you're managing a childcare centre, aged care facility, or simply want to make your home safer, our team is here to help.

What Is a Thermostatic Mixing Valve?

A Thermostatic Mixing Valve is a device that blends hot and cold water to deliver a controlled, safe outlet temperature. It ensures that your taps, showers, and other fixtures don’t exceed a certain temperature — typically set at around 38–50°C depending on the environment. These valves are designed to react instantly if there's a fluctuation in either the hot or cold water supply. If one source fails (e.g., if the cold water drops out), the valve will shut off, preventing dangerously hot water from flowing through.

Our team at Mad 4 It Plumbing is fully trained and certified to install thermostatic mixing valves in accordance with Australian Standards and NSW plumbing regulations. We assess your existing plumbing setup and recommend the most suitable valve based on water usage, risk level, and budget. But installation is only part of the job. TMVs must also be tested annually to ensure they’re operating correctly. Over time, these devices can accumulate mineral build-up or suffer from wear, which affects their ability to regulate temperature effectively.
