The Jandy R0465400 Tank Bottom Assembly is a comprehensive lower-body replacement designed to restore stability and sealing performance in Jandy CV-series cartridge filters such as the CV340, CV460, and CV580. Built to original Jandy specifications, it includes the lower tank shell, bulkheads with O-rings, inlet elbow, drain cap, tank O-ring, retaining ring, and union pieces to rebuild the base section fully. Its reinforced polymer composition withstands continuous chemical exposure and pressure variations common to pool filtration systems. Designed for the CV series side-inlet and side-outlet configuration, the assembly reinstates proper hydraulics while offering a cost-effective alternative to replacing the entire filter tank.

Does this part fix seam leaks or bottom cracks?

Yes. Most lower-tank leaks occur at the seam or bulkhead area, and replacing the entire bottom section typically resolves those issues.

Will this affect filtration performance?

Yes. Replacing worn base components often restores proper plumbing alignment and stable operating pressure.

How long does a replacement bottom assembly last?

When installed correctly, the reinforced polymer construction provides long-term performance comparable to a brand-new filter.
