Useful Information

The disinfection of cold water systems is work that can be carried out by competent plumbing operatives with the aim to ensure operatives have the knowledge and skills to undertake the disinfection process.

The training course also covers the actual disinfection process, including a practical examination on a purpose-built test rig by which the tutor can illustrate how disinfection should be carried out. Though the training is primarily aimed at practising plumbing operatives who already have knowledge of hot and cold water systems, it will also be appropriate to water inspectors and others who are involved with the maintenance and management of a water system.
