Copper and a well-designed and maintained pipework system will help to minimise the risk to your customers from diseases that can be communicated through the water service, like Legionella pneumophila.
In many studies, active Legionella populations are observed to be less in copper plumbing systems. The benefit of copper systems; is that copper systems can be thermally shocked. Temperatures above 55oC can be used for prolonged times in copper systems. The additional benefit of copper at higher temperatures is that there is less required time for disinfection, therefore saving energy, water and time.
