Self priming to 5ft this pump will empty a typical 30 gallon (115 Liter) holding tank in less than 3 minutes. Duty cycle of the pump is 15 minutes continuous which means a 180 gallon (680 liter) can be emptied in a single operationIt is recommended that holding tanks be flushed with several gallons of water after each pump out. This will reduce the possibility of a continued build up of sediment in the tank which could cause a potential blockage.Fish Box and Livewell Tank EvacuationThe Jabsco Macerator Pump is the ideal pump for the emptying of Fish box and livewell receptacles. Very often the livewell tank will be above the waterline of the boat, when this is the case gravity can be used to empty the livewell tank.
