This battery-operated pump transfers water at 10 litres (2.6 gallons) per minute. About 23" long with a 1" diameter tip, it can get into narrow crevices and drain them to the last 1/4" of depth, ejecting the water through a 24" flexible output hose.
Simply submerge the tip and press the switch – no hand pumping needed (a big help in tight spots where a manual pump would be awkward to operate). The impeller-style pump resists clogging, so it can be used in water containing light debris.
Two D-cell batteries not included.
Not intended for use with potable water, it is a convenient option for anything from emptying rain barrels to draining plumbing when winterizing a cottage.
