TMV Service

TMV Service


The thermostatic mixing valve (TMV) is a crucial part of keeping everyone safe in your commercial space. Whether it’s providing water to the taps in the school canteen or retail centre toilet block, the TMV must be mixing hot and cold water as intended to reduce the risk of scalding incidents or legionella contamination.

As a minimum, TMVs need servicing annually to ensure water is stored at the correct temperatures that limit growth of Legionella.

Legionella Control

Legionella is a bacterium that can grow and multiply incredibly quickly in water systems – especially those with TMVs that haven’t been installed or maintained to the proper standards.

If ingested, the bacteria can cause a person to develop Legionnaires’ disease, which has the potential to be fatal. So it’s imperative for any commercial space with a thermostatic mixing valve in place to adhere to strict water safety standards and prevent any risk of water being contaminated by Legionella.

Sayes Service Ltd can support your efforts to reduce the chance of Legionella being present in your commercial water system.
