I have used my macerator up to 150 feet runs and pump 100 plus gallons in 10-15 minutes. It has a hose connection for flushing it after pumping tanks that cleans out pump and hoses. After pumping I disconnect the pump and spray the inside propellers with a liberal coat of penetrating oil. It prevents it from sticking after sitting dry.
I ran a dedicated fused circuit from batteries to dump bay and plug the pump into it.
I have different lengths of 3/4 commercial hoses that are adaptable for different distances with a combination of all to 150 feet.
I have never had any problem dumping the tanks. I see no problem with the pump size if the tanks are used proper.
