Our service

A thermostatic mixing valve (TMV) is a device that controls water temperature for baths, showers and other outlets by mixing hot and cold water to produce a temperature-controlled flow that reduces the risk of scalding. TMVs should be serviced at least annually to ensure that they maintain the correct temperature and meet regulation requirements.

What we do

  • The TMV will be accessed and a failsafe test carried out by isolating the cold supply into the valve and the hot tap turned on with a temperature probe reading monitored to check if the hot supply cuts off before the temperature increase above 50oC.
  • Once the failsafe is complete the valve will be isolated, and if valves are present and in good working order then stripped down to complete a clean, descale and disinfection of strainers using a suitable disinfectant and descaler.
  • Once complete, the valve is flushed through and re-assembled and put back into service with the hot temperature set to between 39-43oC.
  • If a valve fails this test there will be recommendation made for the TMV to be replaced.
  • A report will be completed detailing the work completed on each valve with recommendations included.
