DC portable waste pump is the ideal solution for emptying holding tanks on recreational vehicles and avoiding dump stations. The macerator section grinds waste down to a particle size of 1/8 inch maximum so it can easily be pumped through a garden hose. The pump section is self-priming, permitting the unit to be mounted above the tank in a convenient location. Empties most recirculating toilets in less than 2 minutes; empties a typical 30-gallon holding tank in less than 3minutes.
