Hayward Econo Base with Loop for Perflex Extended-Cycle DE Filters | EC1161LK

The Hayward Econo Base with Loop (EC1161LK) is the OEM replacement modular base for Hayward EC40 and EC50 Perflex Extended-Cycle DE filters, restoring the structural foundation and plumbing loop position that keeps the filter housing properly supported and oriented. Specifications Hayward Part Number EC1161LK UPC 610377025423 Poolaroo Pro Tip When replacing this base, inspect the filter tank's lower O-ring and drain plug for wear at the same time. Addressing all base-level sealing points in a single service visit prevents follow-up leaks and avoids draining the system a second time.
