Protecting Potable Water Irrigation systems can draw fertilizer or debris back into drinking water during pressure reversals. Backflow preventers stop that pathway. Common Residential Types Pressure vacuum breakers (PVB) are common where code allows; reduced pressure (RPZ) assemblies add protection where hazards are higher.
