A Vacaflush has a foot pedal and flushes like an airplane. Electric Flush has a button. There are electric flush that use freshwater from the tank, however most use raw water.
Is the pump for the dead running and not flushing water? Or is the pump not running at all. You can pull the intake hose from the seacock, install a hose connector (male-male), then an extension of hose that goes into a bucket. Fill the bucket with marine/RV antifreeze (propylene glycol) and start flushing. Turn-on your battery charger while to do it.
Raw Water: Drawn from a through-hull using the water the boat is floating in. (regardless of whether the body of water is freshwater or saltwater).
Fresh Water: Drawn from the freshwater tanks.
