How to use it

  • Service TMVs at the interval set by your risk assessment and the manufacturer, recording the delivered blended temperature.
  • Test the fail-safe so the valve shuts off flow if the cold supply fails, and note pass/fail.
  • Clean or replace strainers and filters, descale, and disinfect components, recording each step as TMVs sit at growth-permissive temperatures.
  • Log any failed valve as an action for repair or replacement and re-test after work; verify targets against HSG274.
