Until the late 90s, in the UK, Europe and North America, regulations and standards for thermostatic mixing valves were either non-existent or full of holes. However, the Department for Health realised that scalding within NHS properties was becoming a threat to the health and safety of patients and staff within the facility and the existing thermostatic mixing valves were not adequate for the task.
Elderly and disabled people are at a much higher risk of scalding from hot water. In many cases, a carer or nurse will leave the patient unattended to climb into the bath but, they’re not able to remove themselves from scalding temperatures quickly enough due to reduced mobility. Preventing water from running through taps at scalding temperatures helps to remove this problem.
Realising that the problem must be solved, the NHS looked to the WRc and industry bodies, including Reliance Water Controls in order to create standards and regulations for the thermostatic mixing valves designed for installation in hospitals and nursing homes. The regulations would state that thermostatic mixing valves for these environments must be of a suitable quality, built in ISO 9001 accredited facilities, capable of functioning under extreme supply conditions which are common in the UK and, most importantly are to be third party tested by an approved tester and not self-certified.
TMV3 valves offer a much higher level of protection than other valves across a wider range of pressures and are most commonly used in hospitals and healthcare facilities to protect vulnerable people from scalding. TMV3 valves can react much more quickly in shutting off water flow if the cold water supply fails or temperatures rise above safe levels.
At Reliance Water Controls, we have worked closely within the TMV3 scheme to ensure that our products are suitable for these environments and provide a safe water supply. In addition, we continuously work with industry organisations to raise awareness of the dangers of scaling in young and vulnerable people in order to help prevent accidents in the future. 20 years after our first thermostatic mixing valve was put on sale, we are now recognised market leaders in their supply. Our organisation was instrumental in the writing, promotion and technical support of the NHS’s D08 engineering specification which is now a worldwide benchmark for thermostatic mixing valves.
