TMV Servicing & Installation

Professional TMV servicing, maintenance and installation to help maintain safe outlet temperatures, support effective operation and reduce the risk of scalding. 

When should TMVs be serviced or installed?

Thermostatic mixing valves (TMVs) are used to blend hot and cold water to provide a controlled outlet temperature, helping to reduce the risk of scalding at designated outlets.

Routine servicing is important to check that TMVs are operating correctly, maintaining the required temperature and remaining suitable for continued use. Servicing may also identify issues such as scale build-up, worn components or poor temperature control that require further action.

New TMVs may be required where additional temperature control is needed, where existing valves are unsuitable or beyond repair, or where recommendations have been made following a Legionella risk assessment, site inspection or compliance review.

BrodexTrident can provide routine TMV servicing, maintenance and installation as part of an effective water hygiene and temperature control programme.

Why choose BrodexTrident for TMV servicing & installation?

Water hygiene-focused servicing

Our engineers understand the role TMVs play in managing outlet temperatures and the importance of maintaining them as part of an effective water hygiene and scalding risk control programme.

Practical site-based support

We can assess existing TMVs, identify maintenance or replacement requirements and advise where new valves may be needed based on site use, risk and system conditions.

Support with ongoing compliance

Routine servicing and maintenance help ensure TMVs continue to operate effectively, while clear reporting supports dutyholders with ongoing inspection, maintenance and compliance records.

What can TMV servicing & installation include?

Routine TMV servicing

Servicing can include inspection, cleaning, descaling where required, temperature checks and assessment of valve performance to confirm the TMV is operating correctly.

Maintenance and component replacement

Where servicing identifies worn, damaged or defective components, we can carry out appropriate maintenance or recommend replacement where the valve is no longer suitable for continued use.

New TMV installation

We can install new TMVs where temperature control is required, replacing unsuitable arrangements or introducing additional protection at designated outlets.

Need TMV servicing or installation?

If a Legionella risk assessment or site inspection has identified redundant pipework, dead ends or unnecessary dead legs, BrodexTrident can assess the required works and provide a practical remedial solution.

TMV servicing and installation FAQS:

How often should TMVs be serviced?

TMVs should be inspected, tested and maintained at suitable intervals to ensure they continue to control outlet temperatures effectively. The appropriate frequency should take account of the site risk assessment, the type of premises, manufacturer recommendations and the condition and performance of the valve. HSE guidance emphasises that TMVs should be monitored and maintained so that temperature controls remain effective.
