17-Year-Old Lawn Pump Failure: Repair or Replace?

Evaluating an Aging Irrigation Pump

A 17-year-old Sta-Rite 1.5 HP lawn pump stopped working after storms. The timer (Intermatic) still ticks, but no water flows when manually activated. Breakers are fine. A repair technician recommended replacement based on age alone.

Age Assessment

17 years exceeds the typical lifespan for residential irrigation pumps (10-15 years). At this age, multiple components (bearings, seals, impeller, motor windings) are likely worn. Repair costs often approach replacement cost without guaranteeing longevity.

DIY Replacement Tips

1. Document the existing setup: Take clear photos of all piping, wiring, and mounting before disassembly.
2. Match specifications: Select a replacement pump with identical HP, voltage, pipe connection sizes, and similar dimensions.
3. Use quality sealants: Apply PTFE tape or pipe thread sealant on all threaded connections.
4. Prime properly: Fill the pump casing completely before starting to prevent seal damage.

Consider upgrading to a more energy-efficient model with a longer warranty. Modern pumps often deliver better performance at lower operating costs.
