What is Backflow Prevention?
Backflow occurs when water flows in the opposite direction from its intended path, potentially allowing contaminants, chemicals, bacteria, or other hazardous substances to enter a clean water supply. Backflow prevention devices are designed to protect drinking water systems from these risks.
Regular backflow testing and RPZ valve testing are required by many municipalities and water authorities to verify that these devices are functioning correctly.
