Quality with no restrictions. With the Jandy swing check valve, the diverter swings completely open, out of the flow path, resulting in higher flow with minimal back pressure and virtually no water turbulence. The Jandy swing check valve is equipped with a clear removable top for ease of service and inspection. The spring loaded flap allows the valve to be mounted in any position. The valve is constructed of CPVC and fitted with 100% silicone check seal.
