Whether you need an existing device tested, a fault investigated or a new device installed, contact our team to discuss your property’s requirements.

TMV Testing & Servicing

 Thermostatic mixing valves (TMVs) blend hot and cold water to deliver water at a controlled temperature, helping reduce the risk of scalding.

Contact our team to arrange testing or servicing, or to discuss a valve that isn’t maintaining the correct water temperature.
