Basepump is an extremely reliable, very powerful, water powered backup sump pump system. With no battery to wear out or maintain, no charger to plug in or monitor, Basepump is designed as an automatic, independent system from the primary sump pump. Basepump is essentially in a class by itself. Mounted on the ceiling, high above the sump, it doesn't have to fight the downward force of the water that most competitors' pumps must push up vertically. For this reason, Basepump consistently removes more water per hour than other water powered backup sump pumps and even rivals the best battery powered backup sump pumps, short- and long- term. Period. So instead of a flooded basement because of a sump pump failure or a power failure, install a water powered Basepump backup sump pump before it happens.
