Have you done YOUR annual thermostatic mixing valves testing?
Thermostatic mixing valves testing is mandatory, and must be carried out by a qualified plumber on an annual basis. CRG Plumbing are the experts when it comes to helping you comply with TMV testing requirements in Campbelltown and Greater Sydney areas.
What is a thermostatic mixing valve?
A Thermostatic Mixing Valve (TMV) is a valve that blends hot water (stored at temperatures high enough to kill bacteria) with cold water to ensure constant, safe outlet temperatures preventing scalding. Commonly found in nursing homes, child care centres and disabled toilet blocks, fitted to showers and hand basins.
The TMV circulates and mixes hot and cold water and then distributes warm water at a temperature less than 50°C. They MUST be tested on a yearly basis.
