  • Maintenance and repairs. If necessary, we’ll carry out TMV maintenance and repairs. We may perform minor adjustments or replace broken or worn-out components to keep the TMV operating optimally. Carrying out regular TMV maintenance helps to prevent potential failures.
  • We carry out precise calibration and testing to check that the valves are accurately maintaining safe water temperatures at a safe and consistent level. We’ll measure and record the mixed water temperature to ensure it is between 39°C and 43°C.
  • Clean, scale and disinfect. As part of a TMV service, we’ll isolate each thermostatic mixer valve and then clean, descale and disinfect the valve components and fine mesh strainers. This helps to remove accumulated sediment, debris, or microbial contaminants, keeping the TMV clean, hygienic, and functioning optimally.

What does TMV stand for?

TMV (Thermostatic Mixing Valve) are valves that use a temperature sensitive element and blend hot and cold water to produce water at a temperature that safeguards against the risk of scalding

What types of TMV’s are available?

There are mainly two types of TMVs.  These are the difference between TMV2 and TMV3 valves:

TMV2 valve is the most common valve used in domestic settings.
It must be regularly maintained to meet the national and international standards are met, valves designed to work with water pressure that falls within 0.1 -1.0 bar (BS EN 1287) and 0.5 bar – 5.0 bar (BS EN 1111)

Unlike TMV2s, TMV3 is mostly used in a hospital or healthcare environment. You will rarely find a TMV2 in care homes or hospitals. This is because TMV2 does not meet NHS requirements. TMV3 is also designed to work with water pressure that falls within 0.2 bar – 1.0 bar (Low Pressure D08) and 1.0 – 5.0 bar (High Pressure D08).

What temperature should a TMV valve be set to?

Typically between 38°C and 46°C depending on outlet use.
In healthcare scenarios HTM 04 has specific temperature setting guidance

What servicing is require on a TMV?

TMVs are fitted to minimise scald risk, they require regular maintenance to ensure hot water is reaching the outlet at a suitable temperature.

The maintenance usually includes:
Fail-Safe Testing
Full Annual Service
Lubron can test, failsafe, service, calibrate & replace all types of industry approved TMVs

Can I install a TMV valve that feeds many outlets to reduce install and maintenance cost?

No – guidance recommends valves that are incorporated into the tap or installed as close to the outlet as possible usually within 2 meters. This is to reduce the Legionella growth after the valve. As valves are set to 38-46°C this is an optimum growth temperature therefore the balance of scalding versus bacteria growth need to be carefully assessed.
