The Magic Plastics 0821-20C is a 2" slip x slip swing spring check valve featuring a transparent, chemically resistant body that fits seamlessly into pool, spa, and irrigation plumbing. Its internal swing-spring mechanism guarantees unidirectional water flow and stops backflow or siphoning the moment the system cycles off. Solvent-weld slip connections on each end deliver tight, permanent joints without mechanical fasteners. The clear housing offers an unobstructed view of the valve seat for on-the-spot verification of proper function. Engineered to resist pool treatment chemicals and ultraviolet degradation, this valve provides years of consistent, low-maintenance performance.

Key Benefits

• 2" Slip x Slip Solvent Weld Design: Slip fittings on both ends create robust, leak-proof solvent-weld bonds in pool, spa, or irrigation piping systems.
• Swing-Spring Mechanism for One-Way Flow: Automatically blocks reverse flow and siphoning to protect equipment and maintain proper circulation when the system shuts down.
• Clear, Corrosion-Resistant Body: Transparent construction lets you visually verify internal operation while the material resists degradation from pool chemicals and UV radiation.
• Ideal for Pools, Spas, and Irrigation Systems: Versatile enough for residential and commercial water systems that require dependable backflow protection.
• Low-Maintenance & Long-Lasting: High-quality materials and spring-assisted operation minimize service intervals and deliver steady, reliable performance over time.
