How Often do TMVs Need Servicing?
TMV Servicing is needed “Where the risk assessment considers fitting TMVs appropriate, the strainers or filters should be inspected, cleaned, descaled and disinfected annually or on a frequency defined by the risk assessment, taking account of any manufacturers’ recommendations.” HSG 274 – p.2.164
Regular TMV servicing and maintenance check, temperature monitoring and failsafe testing is required to ensure your TMV’s perform at the NHS Model Engineering Specification Level. If a valve fails a TMV servicing and maintenance test, the valve must either be serviced in accordance with the NHS Model Engineering Specification, or if it can not be serviced it should be replaced.
Regular & on-going TMV servicing maintenance tests and failsafe testing should be carried out to demonstrate adequate thermal performance is being maintained. Get in touch to book your TMV servicing maintenance!
