Inspection of water systems

System & Water Inspection services

Whether there is an anomaly with your water sampling findings, or your equipment isn’t working as well as it used to, let Lubron experts take a look inside the water system to isolate the problem.

As part of a Legionella prevention programme and to comply with generic health and safety requirements it is important that water systems are inspected to ensure they are operating correctly. The dangers of cross-contamination, bacteria growth and scalding caused by inefficient temperature control are just a few examples of the results of an ineffective system.

Lubron will test the components of the system, inspect the interior of the plant and record and report the findings and any recommended remedial action to you.


How often should temperatures be taken for Legionella control?

HSG274 Part 2 states temperatures should be taken every month. Site personnel can be trained to carry out these tasks alternatively Lubron engineers can cover if the resource is not available.

How cold should my cold tap be?

HSG274 Table 2.1 states temperatures at cold taps should be below 20°C after 2 minutes of running the tap.

Can anyone do the Legionella tasks?

Service providers should also ensure that their staff and contractors are
competent to carry out the task safely. They should be properly trained to a
standard appropriate to the various tasks they perform, such as risk assessment, advising on water treatment measures, sampling or cleaning and maintaining water systems. The Legionella Control Association administers a Code of Conduct for organisations providing services to occupiers/owners of water systems. This Code of Conduct does not have legal status but may give guidance to duty holders about the standards of service they should expect to receive from service providers who abide by the Code.

How hot should the taps be?

Hot taps should reach a minimum of 50°C (55°C in healthcare premises) within a minute of running

What is a TMV (Thermostatic Mixing Valve) and do i need one?

A TMV is a valve that prevents scaling by mixing hot and cold water, these are often over used and you should assess whether the TMV fitting is required, and if not, remove. Where needed, inspect, clean, descale and disinfect any strainers or filters associated with TMVs.

To maintain protection against scald risk, TMVs require regular routine
maintenance carried out by competent persons in accordance with the
manufacturer’s instructions. There is further information on our website here
