How long should a well pump last?

A quality submersible well pump typically lasts 10-15 years under normal conditions. Jet pumps may last 10-20 years since they're above ground and easier to maintain. Factors affecting lifespan include water quality (sediment, sand, minerals), pump cycling frequency, proper sizing, and electrical stability. Some pumps in ideal conditions last 20+ years, while pumps in harsh conditions may fail in 5-8 years.

Is it better to repair or replace a well pump?

Replace rather than repair if: the pump is over 10 years old, repair costs exceed 50% of replacement cost, you've had multiple repairs in recent years, the motor has failed, or water quality has damaged internal components. Repair makes sense for: newer pumps with minor issues, problems with surface components (pressure switch, control box), or single failures in otherwise healthy systems.

How much does well pump replacement cost?

Well pump replacement typically costs $1,500-$4,500 including the pump and professional installation. Shallow well jet pumps cost $800-$1,500. Submersible pumps for 100-300 foot wells cost $1,500-$2,500. Deep well pumps (300+ feet) cost $2,500-$4,500 or more. The primary cost factor is well depth—deeper wells require more labor and larger pumps.

What are the signs of a failing well pump?

Key warning signs include: pump running constantly or cycling rapidly, low or fluctuating water pressure, air sputtering from faucets, unusual noises (clicking, grinding, humming), dirty or sandy water, high electricity bills, and complete loss of water. If your pump is showing multiple symptoms, especially if it's over 10 years old, replacement is likely needed.

Can I replace my well pump myself?

DIY well pump replacement is not recommended for submersible pumps. They require specialized equipment to pull hundreds of feet of pipe and pump, and improper installation can damage the pump, contaminate your well, or create safety hazards. Jet pumps and surface components are more accessible but still involve electrical work that should be done by professionals.
