NDS 1-1/2 in. Plastic Spring Loaded Foot Valve with Screen - 1/2 lb. Spring Check Valve, Backflow Prevention for Pools, Spas, Irrigation, Industrial Systems

The NDS 1-1/2 in. x 1-1/2 in. Plastic Spring Loaded Foot Valve is a durable PVC check valve with integrated screen designed to prevent backflow while maintaining prime in suction lines. Featuring a 1/2 lb. spring for positive sealing without back pressure, reinforced poppet for reliability, and stainless steel spring construction, this valve ensures one-way flow in pressurized systems up to 200 PSI at 72°F.

Ideal for swimming pools, spas, irrigation systems, industrial pumps, and any application where backflow prevention is critical to protect pumps from dry running or contamination. The foot valve design with debris screen keeps out sediment, sand, and particles, extending pump life in well, pond, or tank suction setups. White PVC body resists corrosion, chemicals, and UV exposure for long-term outdoor use.

Key specs: 1-1/2 in. IPS FPT x FPT connections, EPDM seals, leak-resistant operation. Easy inline installation—water pressure opens the spring-loaded poppet for forward flow; closes instantly to block reverse flow. Perfect for pool pumps, spa circulation, drip irrigation, agricultural wells, and industrial water transfer. NSF/ANSI 61 compliant materials ensure safe potable water use where applicable.
