TL;DR
A jet pump is an above-ground well pump that creates suction with a motor-driven impeller and a venturi ejector, drawing water up rather than pushing it from below like a submersible. Shallow-well versions with the ejector in the pump body lift from about 25 feet; deep-well models lower the ejector into the well on twin pipes to reach 100 feet or more at reduced flow.
What it means
A jet pump is an above-ground well pump that creates suction with a motor-driven impeller and a venturi ejector, drawing water up rather than pushing it from below like a submersible. Shallow-well versions with the ejector in the pump body lift from about 25 feet; deep-well models lower the ejector into the well on twin pipes to reach 100 feet or more at reduced flow. Mounted in basements and well houses, it needs to stay primed, and chronic prime loss points to a foot-valve or suction-line leak.
