This 3/4″ water check valve is installed in the inlet side of the circulation pumps plumbing to prevent the back flow of water through the circulation pump once the jet pump is activated.
Works on Tiger River Spas, Hot Spring Spas, and Limelight Spas..
All water check valves have arrows stamped on the outside to indicate the direction of flow which should be pointer towards the circulation pump..
Troubling Shooting: The symptoms of a non-operative check valve are.
* Water Leak – If water is leaking from around the check valve, it should be replaced. * Rattling – A rattling check valve indicates that water is not being allowed to flow properly past/ through the check valve. * Verify the check valve is installed with the flow in the correct direction. * Heater High-Limit Tripping – Poor water flow through the check valve could lead to heater high-limit tripping. Ensure the check valve is n.

【PVC Ball Check Valve】Schedule 80 PVC ball check valves have a spherical ball inside the valve body which works as a check to allow flow in one direction and close off to prevent back-flow..
【INSTALLATION TIP】PVC union check valves are designed for VERTICAL installations, MUST be used in an upflow position to work properly. Check valves MUST be installed with the valve's flow arrow pointing in the direction of the flow. Do not install valve upside down.（NOTE: NO SPRING).
