The WATTS 0386470 is a 3/4 inch dual check valve backflow preventer with an intermediate atmospheric vent. This valve prevents reverse flow of hot or cold polluted water into potable water supplies, specifically for non-potable applications. Designed for continuous pressure, non-health hazard uses in smaller supply lines, it features a bronze body, stainless steel internal parts, an integral strainer, and two durable rubber check valves. This product does not comply with low-lead standards for human consumption.
Prevents backflow in non-potable water systems with durable bronze construction and versatile installation options.
