Which process is recommended for disinfecting a new plumbing system?

The recommended process for disinfecting a new plumbing system is chlorination. This method is widely accepted and utilized because chlorine is effective at killing a broad spectrum of pathogens, including bacteria and viruses, that could contaminate the water supply. The chlorination process typically involves adding chlorine or chlorine compounds to the water, which then needs to circulate through the plumbing system for a designated period to ensure effective disinfection.

Chlorine continues to provide a residual level of disinfection, which helps to prevent recontamination of the water throughout the plumbing system. Additionally, this method is relatively simple and cost-effective, making it the standard choice for many new plumbing installations.

While other disinfection methods like ultraviolet radiation, boiling water, and ozone treatment exist, they may not be as practical for large-scale plumbing systems. Ultraviolet radiation requires clear water to be effective and typically doesn't provide a lasting residual disinfectant effect. Boiling water, while effective for immediate disinfection, is not practical for whole plumbing systems. Ozone treatment, though powerful, involves more complex equipment and the creation of ozone, which while effective, may pose safety concerns if not managed properly during and after the treatment process.
