The present invention is a submersible pump system that includes a main housing, which is watertight and contains a submersible pump therein. There is a liquid suction inlet connected to the main housing and adapted for functional connection to a liquid source. This may be a direct pipe connection, or an open intake. There is also a one way check valve functionally connected to the main housing and located downstream from the liquid suction inlet, adapted to permit liquid to flow from the inlet to the main housing and to prevent liquid from oppositely flowing. The submersible pump has electrical power wiring and control wiring connected thereto and extending out of the main housing with a watertight seal. The pump has a submersible pump inlet to pump liquid from the main housing, and a pump outlet directly connected to a liquid flow outlet extending out through the main housing for liquid distribution therefrom. When the pump is turned on, the liquid in the main housing is removed, creating negative pressure which draws water into the housing from the connected source which may be below the pump system.
