Maintenance of Thermostatic Mixing Valve (TMV) and Failsafe Checks. Carried out by City and Guilds and NVQ Qualified Engineers. Water Safe Registered.
The HSE's ACOP L8, HSG 274 and HTM 04-01 give guidance on the effective measures required to reduce the potential risk of Legionella. All fixtures, fittings and valves have a purpose, for example, thermostatic mixing valves (TMV) mix hot & cold water to reduce the hot water temperature to a safe temperature to wash and bathe in. However, these "safe" water temperatures fall within the temperature range that could promote bacterial growth. A failing mixing valve can also increase the risk of scalding.

Thermostatic Mixing Valves
Advice is often given that TMV valves need regular maintenance. This is not true. TMV valves need to be regularly inspected (called a failsafe check).
A failsafe check is designed to ensure that the TMV valve is in working order and identifies any maintenance requirements. Only if the TMV valve fails the failsafe check do you need to maintain or replace the valve.
The requirements for TMV inspection and maintenance are found in the HSE's ACOP L8, HSG 274 part 2 and Specification D-08 which is a supplement to HTM 04-01.
HTM 04-01 from the Department of Health requires the use of Water Safe registered plumbers to install and maintain hot and cold water systems at healthcare sites. This requirement includes the checking and maintaining of TMV valves.
