Multi-pump system with system check

A liquid pump system comprising:

• a plurality of liquid pumps that are powered by a common low voltage DC energy reservoir to pump a liquid;
• an AC/DC power supply to convert AC power from an AC electric power source, into a low voltage direct current to charge the low voltage DC energy reservoir;
• an energy level detection subsystem for the low voltage DC energy reservoir configured to determine a percentage of energy remaining in the low voltage DC energy reservoir and send signals to indicate when the low voltage DC energy reservoir reaches a specified percentage of stored energy;
• a set of liquid level sensor subsystems configured to turn on each of the plurality of liquid pumps one at a time as a liquid level rises, and configured to turn off each of the plurality of liquid pumps one at a time as the liquid level lowers;
• a pump-detection subsystem configured to detect whether each specific pump of the plurality of liquid pumps is running or not and also to send detection signals to indicate the operating status of each said specific pump;
• and
• an analysis module configured to receive the detection signals and in response to a high level signal perform real time checks of the plurality of liquid pumps to verify proper operation of the plurality of liquid pumps, and configured to cause communications to be transmitted to one or more recipients when the analysis module detects improper operation of a subset of the plurality of liquid pumps.
