How Long Should a Well Pump Last?
Need Help With Your Well?
Average Well Pump Lifespan
A quality submersible well pump typically lasts 10-15 years under normal conditions. However, lifespan varies widely based on several factors:
- Water quality — Sand, sediment, and minerals shorten life
- Usage — Heavy use wears pumps faster
- Electrical conditions — Voltage problems damage motors
- Pump quality — Better brands last longer
- Proper sizing — Oversized or undersized pumps fail sooner
Factors That Shorten Pump Life
Sand and Sediment
Sandy water is abrasive. It wears impellers, seals, and bearings. Pumps in sandy wells may last only 5-7 years.
Short Cycling
Each start puts stress on the motor. A pump that cycles frequently (due to a bad pressure tank) wears out much faster.
Running Dry
Pumps need water for cooling and lubrication. Running dry even briefly can cause permanent damage.
Lightning and Power Surges
Electrical damage is a leading cause of premature pump failure in rural areas.
Signs Your Pump Is Failing
- Reduced water pressure or flow
- Pump runs continuously
- Higher electricity bills
- Sputtering or air in lines
- Strange noises from the well
- Dirty or sandy water (new occurrence)
- Tripping breakers
Extend Your Pump's Life
- Maintain proper pressure tank air charge
- Install a surge protector
- Address water quality issues (sand, sediment)
- Don't let the well pump dry
- Annual check-ups to catch problems early
When to Replace vs Repair
If your pump is over 10 years old and having issues, replacement is usually more cost-effective than repair. Newer pumps are more efficient and come with warranties.
