Want to prevent scalding and bacteria build up in your water?
Thermostatic mixing valves (TMV) are essential for maintaining the temperature of your water at safe levels. Additionally, backflow testing ensures that your water is safe from water contamination and remains drinkable.
Allanna Plumbing has 35+ years of experience maintaining TMVs and conducting backflow tests.
Queensland regulations require that every installed TMV must undergo testing and be commissioned every 12 months. This ensures that the valve is functioning properly and the water is used safely.
