Description
The OEM Waterway Tank Bottom 550-4407 is a precision-molded replacement base for Crystal Water Cartridge Filters, restoring the structural foundation your filter needs to operate reliably. Engineered for universal compatibility with both legacy and current filter head styles, this tank bottom drops in without modifications or adapters. Fabricated from heavy-duty, chemical-resistant materials, it withstands sustained high-pressure operation and prolonged contact with treated pool water. Swapping in a fresh tank bottom eliminates leaks at the base, preserves internal pressure, and keeps your filtration system performing at its best.
