The Little Giant line of ABS pumps (1-ABS, 2-ABS, and 3-ABS) are perfect for condensate and other waste-water removal. Designed for in-pan placement, these shallow pan pumps offer next generation technology for air conditioner condensate removal. The pumps are totally submersible, with a built-in, advanced non-mercury mechanical switch that automatically triggers operation when the condensate in the pan or reservoir reaches a preset level. Then, automatic shutoff occurs when the condensate level drops. These pumps are light weight and compact, with high lift and quiet operation.
