A surface-mounted pump that uses a venturi to draw water from a shallow well.
A jet pump sits above ground and pulls water up the well using suction created by a venturi nozzle. Single-jet (shallow) versions work to about 25 feet; double-jet (deep) versions can reach 80 to 110 feet. Jet pumps lose efficiency rapidly with depth and are largely obsolete in Utah, where most modern wells use submersible pumps placed below the water level.
