PVC check valves perfect for pond pumps. Ideal to stop backflow of water back into pond pump. Tapered valve body design and enlarged valve chamber reduces chatter and turbulence.

Available in Slip to Slip or FPT to FPT styles. Slip to Slip (S x S) is a smooth walled check valve which your PVC pipe can slide into and be cemented in place. The (FPT x FPT) check valves have female pipe threads on both ends to allow screwing into your pipes or fittings.

•  These PVC swing check valves are recommended whenever maximum flow is needed.
•  Swing checks have full flow design for maximum GPM and are completely non-metallic  ensuring years of use in water
•  Ideal for use in fresh or salt water, are rated to 100 PSI, mounted vertical or horizontal, and can be used with schedule 40 or 80 PVC pipe

Swing vs Spring:
Swing check valves utilize a disc attached to a hinge which allows it to swing freely. When there is downstream pressure, the disc swings away from the valve seat to allow the liquid to flow through. Reverse flow is stopped by the disc swinging back into place due to gravity or back pressure. Generally, swing check valves allow for higher flow capacity compared to spring check valves but are often noisier and are limited by their orientation.

Spring check valves are suitable for use in both vertical and horizontal orientations and are ideal for applications that require quick responses to flow changes. They use a closing mechanism, such as a disc or poppet, combined with a spring that allows for downstream flow but stops reverse flow altogether. When compared to swing check valves, spring check valves tend to be more compact in design, making them suitable for installation in tight spaces. They also tend to be quieter, while the spring mechanism ensures a faster response to backflow.
