alternative sump pump systems can be driven by municipal water pressure. water-powered ejector pumps have a separate pump, float and check valve. the float controlling a backup pump is mounted in the sump pit above the normal high water mark. under normal conditions, the main electric powered sump pump will handle all the pumping duties. when water rises higher than normal for any reason, the backup float in the sump is lifted and activates the backup sump pump. an ejector pump can also be connected to a garden hose to supply high-pressure water, with another hose to carry the water away. although such ejector pumps waste water and are relatively inefficient, they have the advantage of having no moving parts and offer the utmost in reliability.
