1 in. SCH-40 PVC Swing Check Valve ASTM ANSI

Water naturally seeks the path of least resistance. When a pump shuts off or water pressure drops, water can flow backward through your plumbing system. This reverse flow, known as backflow, can reduce system efficiency, damage pumps, contaminate clean water, and place unnecessary stress on filters, valves, and other equipment.

A swing check valve is designed to prevent this problem automatically. It opens when water flows in the intended direction and closes when flow stops or begins to reverse, allowing your system to operate safely without manual intervention.

The 247Garden 1 in. Schedule 40 PVC Swing Check Valve provides dependable one-way flow protection for irrigation systems, hydroponics, aquaponics, water pumps, pools, ponds, filtration systems, and general plumbing applications. Built with a durable Schedule 40 PVC body and premium internal components, it delivers reliable performance while resisting corrosion in demanding environments.

Manufactured to ASTM and ANSI standards, this valve is an excellent choice for both residential and commercial installations where preventing backflow is essential.
