Protect and Maintain Piping

Hot and cold water services maintenance

The maintenance of your hot and cold water system is important to the health of all those who use your building because if left untreated, bacteria can start to multiply. Also, debris, sediment, scale, corrosion and biofilm can build up that will impact on the efficient running of your water system. It is important, therefore, to carry out a hot and cold water conditions survey annually to look for any signs of the above and to prevent the build-up on Legionella or E. coli in your system. RPZ valves also need to be tested each year to make sure they are working properly and this can only be carried out by engineers, like ours, who are WRAS (Water Regulations Advisory Service) approved.

Water Testing & Maintanence

Legionella Control Services

Legionella bacteria are found in water systems and the possibility of catching Legionnaires’ disease strikes fear into the public at large. While illness resulting from Legionella may be rare, the bacteria can take hold and multiply quite easily – in redundant pipework, where limescale builds up, or when temperatures are allowed to rise to optimum growth levels. This is why it’s so important to have our team of Legionella specialists available to undertake regular testing (with our UKAS approved laboratories), analysis, sampling (to BS 7592) and risk assessments to recommend actions for Legionella risk management. Should it be needed, our qualified engineers can also carry out any and all maintenance and repair work to your water systems.
