The Basepump RB750-EZ is a water-powered backup sump pump that uses your home's municipal water supply to move water out of the sump pit when the main pump fails or loses power. It mounts at the ceiling, so it does not fight downward water pressure the way floor-level water-powered pumps do, which Basepump says reduces strain on the unit. There is no battery to replace or charger to watch, and the package adds a DIY installation kit and a built-in brass backflow preventer. It suits homes with normal sump water volumes that have reliable city water pressure; homes on wells or with high water tables should look at battery backups instead.

The Basepump RB750-EZ is a water powered backup sump pump for homes with normal volumes of sump water. It runs on municipal water pressure, so it needs no battery, wires or charger. It works independently of the main pump and starts automatically when the water in the sump pit rises.
When water rises above the normal high water level, the float lifts and opens a valve. Municipal water then flows through the ejector, creating suction that draws sump water out of the pit and discharges it outdoors. A pre-set timing control keeps the pump running until the sump is fully drained. Float position and cycle timing are both adjustable.
The pump mounts on the ceiling, above the sump pit, so it does not work against downward water pressure and stays clear of corrosion, debris and scale in the pit. It has no motors, turbines or other mechanical parts, and the float is hydraulic with no electronic components. The housing is heavy-duty, corrosion-resistant polypropylene. The package includes a do-it-yourself installation kit, a brass backflow preventer, and a water alarm.
