reduced pressure zone (RPZ) valves

A Reduced Pressure Zone (RPZ) valve is a special device used in plumbing systems to prevent contaminated water from flowing back into the clean water supply. It works by creating a safe separation point, or "zone," with a reduced pressure area that triggers the valve to shut if backflow occurs. This ensures that pollutants, like bacteria or chemicals, can't flow back into drinking water lines, maintaining water safety. RPZ valves are commonly used in commercial and industrial settings where there's a higher risk of contamination entering the potable water system.
