Little Giant 505055 Reviews

Rated 5 out of 5 by from Little Giant Drainosaur Pumps my laundry sink in the basement. Had it for 15 years before the pump inside the casing died. The pump ran continuously for 8 weeks last spring as I used it to pump the water from our basement. Great product.

  • How do I clean the filter.

    A. The Little Giant 505055 provides cleaning instructions in your owners manual. For the filter it states to: Remove (4) 1/4-20 screen cover plate screws, plastic cover plate, o-ring and screen. Clean inlet screen using a mild detergent and water. Examine o-ring and if deformed, replace with new o-ring. See replacement parts list. Let me know if you need anything else.
