Well Pump Repair Cost: 2026 Prices for Replacement & Troubleshooting
Well pump repairs cost $150–$600 for most component failures (pressure switch, capacitor, pressure tank). A full submersible pump replacement — the most common major repair — runs $800–$2,500 including pulling the pump from depth, the new unit, and reinstallation. Jet pump replacement is cheaper at $400–$1,200 because the pump is above ground and accessible.

Types of Well Pumps
Submersible Pumps (Most Common)
Submersible pumps are sealed units installed at the bottom of the well, typically 10–20 feet above the well bottom. They push water up to the surface. Submersibles are more efficient and quieter than jet pumps, and they are the standard for deep wells (over 25 feet).
Lifespan: 8–15 years depending on water quality and usage
Major cost driver: Well depth. Pulling a pump from 300 feet requires a cable-laying truck and significant labor vs. hand-pulling from 50 feet. Deeper pump = higher labor cost regardless of pump price.
Jet Pumps
Jet pumps are installed above ground, either in the well house or basement. They work by creating suction. Shallow-well jet pumps work to about 25 feet. Deep-well jet pumps can work to 120–150 feet with a separate ejector assembly down the well.
Lifespan: 10–15 years
Advantage: Entirely accessible above ground — service and replacement is much simpler and cheaper than pulling a submersible.
Common Well Pump Problems and Fixes
No Water at All
Check these in order before calling a contractor:
- Circuit breaker: Check the pump breaker (usually a 2-pole 20A or 30A breaker labeled well pump). Reset if tripped.
- Pressure switch: If contacts are burned, the pump will not start. A pressure switch is a $15–$30 part; replacement by a well contractor: $150–$250.
- Low water level in the well: During drought or heavy demand, the well water level drops. If the pump is running but not drawing water, you may need to wait hours to days or lower the pump.
- Burnt pump motor: If the breaker keeps tripping or the pressure switch clicks but nothing happens, the pump motor may have failed. Test with an amp clamp — or call a well contractor.
Low Water Pressure
- Waterlogged pressure tank: If the bladder fails, the tank fills with water only and pressure fluctuates wildly. Replacement: $300–$700.
- Pressure switch set too low: Adjust the cut-in/cut-out settings (typically 30/50 or 40/60 PSI). Requires turning off power — call a contractor if unfamiliar.
- Partially failing pump: An aging pump may run but produce reduced flow. Time for replacement.
Pump Runs Constantly
A pump that never shuts off indicates: pressure tank bladder failure (most common), a water leak causing continuous pressure drop, or the pump cut-out pressure is set too high. Address immediately — a continuously running submersible pump overheats and burns out.
Air in the Water
Sputtering faucets suggest the pump is drawing air, meaning the well water level is below the pump intake. This can be a drought condition (wait it out), or the pump has dropped in position and needs to be lowered or the well yield tested.
Pressure Tank: The Often-Overlooked Component
The pressure tank stores water under pressure so the pump does not cycle on and off with every glass of water drawn. Without a properly functioning tank, the pump cycles thousands of times per day — dramatically shortening its life.
Signs of a failing pressure tank:
- Pump cycles rapidly (turns on and off every few seconds)
- Pressure gauge fluctuates wildly between 0 and cut-out pressure
- Water spits from faucets
- Waterlogged tank (no air charge, tank feels heavy)
Pressure tank replacement: $300–$700 installed. Tank itself is $100–$300; Wellmate, Amtrol (WellXTrol), and Flexcon are the leading brands. A larger tank (44–86 gallon drawdown) means fewer pump cycles and longer pump life.
Water Quality Issues: Iron, Sulfur, Hardness
Private wells are not treated by a municipality. Common water quality issues and their plumbing solutions:
- Iron (rusty stains, metallic taste): Iron filter or water softener with iron removal media. Cost installed: $800–$2,500.
- Hydrogen sulfide (rotten egg smell): Aeration system or chlorination system. Cost: $500–$2,000.
- Hard water (mineral scale): Water softener. Cost installed: $1,000–$3,000.
- Bacteria: UV disinfection system. Cost installed: $500–$1,500. Annual UV bulb: $60–$120.
Well water should be tested annually for bacteria and every 3–5 years for a full panel. Test kits: $30–$150 DIY; professional testing: $100–$400.
Frequently Asked Questions
How do I know if my well pump is failing?
The most reliable signs: sudden loss of water pressure throughout the house, pump that runs constantly, pump that short-cycles (turns on and off rapidly), sputtering or air in the water, sand or sediment in the water, or tripped circuit breakers. Any of these warrants a call to a well contractor — do not wait on a failing pump, as a completely burned-out pump is more expensive to replace than a failing one caught early.
How long do well pumps last?
Quality submersible pumps last 8–15 years. Jet pumps last 10–15 years. Lifespan is reduced by: high-iron water (corrosive), sand in the water (abrasive), frequent cycling from undersized pressure tank, running dry, and power surges. A properly sized pressure tank and surge protector extend pump life significantly.
Can I replace a well pump myself?
Above-ground jet pumps are within DIY capability for someone comfortable with electrical and plumbing work. Submersible pumps are a different matter — pulling a pump from 200+ feet requires a safety rope, wire rope or cable, and often specialized equipment. Without proper technique, you risk dropping the pump down the well. Most homeowners hire a well contractor for submersible replacement. Many states also require licensed well contractors for any well work.
Is well pump repair covered by homeowner insurance?
Standard homeowners insurance typically excludes well pump repair and replacement — it is considered a mechanical breakdown. However, if the pump fails due to a covered peril (lightning strike, for example), the replacement may be covered. Some insurers offer equipment breakdown coverage as a rider. Home warranty plans (American Home Shield, Choice Home Warranty) sometimes include well pumps — check the policy details.
Why does my water pressure drop when I run the washing machine?
This is almost always a pressure tank issue — specifically a waterlogged tank or undersized tank. The washing machine high-flow demand draws down the tank faster than the pump can respond, causing a pressure drop. Check the air pre-charge in the tank (should be 2 PSI below cut-in pressure). If the tank is waterlogged, it needs replacement. If correctly charged but still too small, a larger tank or adding a second tank solves the problem.
What does a well inspection include?
A professional well inspection ($150–$400) typically includes: static water level measurement, pump flow rate test (GPM), pressure system check (tank, switch, pressure), visual inspection of well casing and cap condition, and water sample collection for basic testing. For a home purchase, always get an independent well inspection — the inspector should confirm the well meets your household demand (minimum 5 GPM for family use).
