A foot valve is a type of check valve installed at the end of a pump suction pipe. It uses a spring-loaded poppet or flap that opens when the pump runs and closes tightly when the pump stops. This prevents water from draining back down the pipe, keeping the pump primed and ready for the next start.

While both prevent backflow, a foot valve includes an integral strainer (screen) that filters out debris. It’s also designed for vertical installation at the foot of a suction line, whereas check valves are often used in horizontal pipes.

Install the foot valve vertically at the bottom of the suction pipe, with the strainer at least 12 inches above the tank or well bottom to avoid sediment. Use Teflon tape on NPT threads and ensure the arrow on the body points toward the pump. For flanged connections, use appropriate gaskets and torque bolts to spec. Our installation guide is included with every order.

Pricing depends on size, material, and quantity. For example, a 2″ cast iron foot valve starts at $18 USD/unit (MOQ 50 pcs). A 6″ SS316 flanged model may be $120/unit. Volume discounts apply – request a bulk price list here.
