TMV Servicing
Regular TMV Service intervals also prolongs the life of the Thermostatic Mixing Valve ‘TMV’ which in the long run means less money spent on new valves.
Sherpa can also install new TMV’s to outlets where required.
Sherpa can also install new TMV’s to outlets where required.
Did you know?
Every year around 20 people die as a result of scalds caused by hot bath water and a further 570 suffer serious scald injuries. TMV’s can also be a source of biofilm where legionella bacteria can breed if not maintained accordingly – for this reason they should form part of the sites legionella risk assessment and legionella control policy.
Work Estimates
If you know the amount of TMV’s you have onsite and whether you need a legionella risk assessment and or scheme of control then we can work out a price over the phone. If you are not sure it may require a quick site visit to allow us to formally quote you.
Product Performance
Let us check that your Thermostatic Mixing Valve ‘TMV’ is performing to the required standard – for a TMV3, D08 states that the first test must take place 6 to 8 weeks after commissioning and the second test 12-15 weeks later.
Quality Maintenance
Our fully qualified staff can carry out your TMV service and TMV maintenance tasks to keep your facility compliant with the relevant codes of practice. If your staff members need training, this can also be provided and documented.
TMV SERVICING
What is a THERMOSTATIC MIXING VALVE :
A thermostatic mixing valve (TMV) is a device used to regulate the temperature of water supplied to wash hand basins and baths & showers.
Its Primary purpose includes:
● Temperature Control: It blends hot water and cold water to maintain a preset temperature, preventing scalding or discomfort
● Safety: By Mixing the water to a safe temperature, TMV’S reduce the risk of burns, especially in environments like hospitals, nursing homes, and homes with children or elderly residents.
“Having worked with Sherpa for several years now, I have to say they are always a pleasure to deal with. Nothing is ever too much trouble… they are so organised and super reliable!
Most importantly though, they have managed to clear our legionella issues in our very old complex buildings. Thank you for your ongoing help and support – a really great crew!”

Any questions?
Here are the most common questions relating to managing legionella control, if you have any questions, you can book a call with us to see how we can help.
-
Legionella is a type of bacteria that can cause Legionnaires' disease, a severe pneumonia-like illness. It thrives in warm water environments, such as hot tubs, cooling towers, and poorly maintained water tanks.
-
Legionella bacteria spread through inhalation of aerosolised water droplets containing the bacteria. This can occur from showers, faucets, cooling towers, and other water systems where water is dispersed into the air.
-
Symptoms typically include cough, shortness of breath, high fever, muscle aches, and headaches. In severe cases, it can lead to pneumonia and even be life-threatening, especially for those with weakened immune systems.
-
To prevent Legionella growth, it's essential to:
Regularly clean and disinfect water tanks.
Maintain proper water temperature (below 20°C or above 60°C).
Ensure good water circulation and avoid stagnation.
Conduct routine inspections and testing for Legionella.
-
Water tanks should generally be cleaned and disinfected at least once a year. However, the frequency may vary based on usage, water quality, and specific regulations in your area.
-
Regulations vary by region, but many jurisdictions require regular risk assessments, maintenance of water systems, and documentation of cleaning and testing for Legionella to ensure public health safety.
-
If Legionella is detected, immediate action is required. This typically involves cleaning and disinfecting the affected system, conducting follow-up testing, and implementing measures to prevent future growth. https://www.hse.gov.uk/legionnaires/legionella-landlords-responsibilities.htm
-
Professional water management ensures that systems are properly maintained, reducing the risk of Legionella growth. Experts can provide the necessary cleaning, testing, and compliance documentation to keep your water systems safe.
You can find more detailed guidance on your duties in the Approved Code of Practice and guidance on regulations

Sherpa Guiding you to being compliant
Legionella Risk Assessment
Becoming compliant starts with a legionella risk assessment. This will clearly identify the potential risks Legionella poses in your water systems.
Legionella Remedial Works
Once the risks have been identified they need to be monitored, removed or replaced. A plan is created to undertake any remedial works to reduce and manage the risks identified.
Legionella Monitoring
After the risks have been understood, your organisation will need to control and manage the ongoing risk of Legionella exposure from your water system to employees and visitors by carrying out ongoing monitoring.
