The Jandy R0465400 Tank Bottom Assembly is an original Jandy replacement base engineered for CV-series cartridge filters including the CV340, CV460, and CV580. Built to restore the structural integrity of aging filter housings, it includes the lower tank body, bulkhead assemblies with O-rings, inlet elbow, drain cap assembly, tank O-ring, retaining ring, and union components for a complete rebuild. Its corrosion-resistant polymer construction helps maintain strong pressure performance and leak-free operation in demanding pool environments. Designed for the CV series side-inlet and side-outlet layout, the assembly reinstates proper flow alignment and long-term reliability while avoiding the cost of installing a full filter tank.
