TMV Maintenance

A TMV is a plumbing valve that mixes hot and cold water.

It regulates and maintains water temperatures so they are at a safe level.

They work by using an internal thermostat to control a mixed stream of water at a designated temperature (usually between 39º and 43º Celsius).

TMV’s also have a failsafe mechanism and this shuts down the valve if there is a hot or cold water supply failure.

It therefore protects your staff, customers and visitors from scalding and thermal shock.

All TMV’s at your place of business, especially in healthcare and social settings, need to be maintained for health and safety compliance.

Thorough TMV Inspections


TMV monitoring must be carefully controlled.

Our team carry all the latest testing equipment, disinfectants and componentry on-board to keep your TMV’s properly maintained and serviced so they work efficiently and safely.

We check for potential scalding by monitoring water temperature because the Department of Health state that hot water should be stored at a minimum of 60º Celsius, dispensed at minimum 55º Celsius to avoid risk of injury.

If temperature has increased by more than 2º Celcius a valve replacement or full service will be required.

We also survey your TMV’s to make sure that all your TMV valves are installed correctly, to specification.

Additionally, our engineers inspect efficiency of TMV operation.

This test makes sure that your TMV’s work properly in case of water supply failure.

If necessary, our engineers can carry out maintenance when they visit, therefore minimising inconvenience to your day to day running of your business.

Following inspection, we provide you with a detailed report where all findings are logged.

Frequently Asked Questions

Browse through our list below to get answers to frequently asked questions on this service:

If they fail, you are at risk of scalding your staff, customers and visitors because TMV’s control the temperature of your water therefore it is important to have regular inspections for compliance.

If you are in a healthcare or social care business you must check them very regularly because the elderly, infirm and children are especially at risk of thermal shock or scalding. If a valve fails it needs replacing or repairing. Your first TMV test should take place up to 8 weeks after installation and then you should have another in 12 to 15 weeks. Following this period, it is wise to get your TMV’s checked twice a year.

There are approval schemes based on regulations in the Building Regulations (Part G 3.66 Prevention of Scalding) states that your TMV’s must comply with European standards En1111 and En1287.
