What does an auto water pump do?

An automatic water pump, often just called an "auto pump," is a device that automatically pumps water from a source (like a well, cistern, or municipal supply) to a destination (like a house, garden, or irrigation system). Unlike a manual pump, it operates without requiring direct human intervention. It typically includes a pressure sensor which turns the pump on when pressure drops (indicating water usage) and off when pressure returns to a set level. This ensures a consistent water supply without the need for someone to constantly monitor and operate the pump.
