Lifespan by pump type
Deep submersibles: commonly 10–15 years, longer with clean water and proper sizing. Jet pumps on shallow wells: 8–12 years with sediment exposure. Constant-pressure VFD systems: motor and controller life varies—follow manufacturer service intervals.
What shortens pump life in Arizona
Iron and sand in Sahuarita-area wells wear impellers. Short cycling from failed tanks heats motors. Running dry during pressure switch failures destroys submersibles quickly. Voltage drop on long wire runs to distant well heads causes overheating.
