An auxiliary jet sump pump, particularly for use with a main conventional electrical sump pump or the like, as a substitute pump in the event the main pump is inoperative, or as a supplemental pump in the event the capacity of the main pump is exceeded. The auxiliary pump is adapted to be mounted in the sump, and discharges into the discharge pipe of the main pump. The auxiliary pump is powered by water under pressure, for example water from the usual municipal water supply. A float-actuated valve is provided which admits water into the auxiliary pump when the water level in the sump rises to a first predetermined level above normal, and which shuts off the water when the water level reaches a second predetermined level lower than the first predetermined level.
