Well Pump Replacement Cost
Free well pump replacement cost estimator. Get an installed-cost range for submersible or jet well pumps based on well depth, horsepower, and labor.
Quick answer
Submersible well pump replacement: $1,500-$3,500 installed for typical depths (100-300 feet). Jet pumps for shallow wells (under 25 feet): $700-$1,500. Deep wells (400+ feet) can hit $5,000-$8,000. The pump itself is $300-$1,200; the rest is labor, well casing access, and incidentals.

How it works
Submersible pumps live at the bottom of the well and have to be physically pulled out for replacement — labor scales with well depth. Jet pumps sit at the surface, so they're cheaper to swap. Adding a new pressure tank at the same time is the standard recommendation if your tank is more than 10–15 years old.
When to use it
When your well pump fails (no water, short cycling, or constant running), when your pressure tank's bladder ruptures, or when you're buying a property with an old well system and want to budget for likely near-term replacement.
Common mistakes
Replacing only the pump when the pressure tank is also failing — you'll be paying for a pump pull twice. Get both inspected at once. Also: trying DIY on a deep submersible — pulling 150+ feet of pipe and wire requires specialized equipment.
How the well pump replacement cost works
Submersible pumps live at the bottom of the well, pushing water up through the drop pipe. Replacement requires pulling the entire string of pipe and pump — labor scales with well depth. Pump cost is $300-$1,200 depending on horsepower. Deep wells often require new wire and pipe simultaneously (they wear out at similar timeframes), adding $500-$1,500. Jet pumps are above-ground for shallow wells, dramatically cheaper to service. The calculator estimates installed cost from depth, pump type, and HP.
When to use it
Budgeting after a well pump fails (no water at the tap, or short-cycling pressure switch). Comparing contractor bids. Planning a preventive replacement on a 12+ year old pump (typical lifespan 8-15 years). Evaluating whether to repair (under $500) or replace ($1,500+) an aging pump.
Common mistakes
- Replacing pump only when wire and pipe are also failing. If the pump is 12+ years old, the drop pipe and wire are too. Replace all three at once — pulling the well a second time costs nearly as much as the first.
- Sizing the new pump differently from the old. A bigger pump pushes more water but burns out the wire if the line is undersized. Match HP to the original specs unless a hydrologist or qualified well company specifies otherwise.
- Skipping the post-installation chlorine shock. Pulling the well introduces bacteria. Always shock-chlorinate after a pump replacement and test the water before returning to use.
Frequently asked questions
How much does it cost to replace a well pump?
Submersible: $1,500-$3,500 for typical residential wells (100-300 feet deep). Jet pump for shallow well: $700-$1,500. Deep wells (400+ feet) can reach $5,000-$8,000 if replacing pipe and wire alongside the pump.
How long does a well pump last?
8-15 years for submersible pumps with good water and properly sized wiring. Jet pumps in shallow wells typically last 10-12 years. Frequent cycling (small or undersized pressure tank) shortens lifespan dramatically.
Should I repair or replace my well pump?
If the pump is over 10 years old or the cost of repair exceeds 50% of replacement, replace. New pumps come with warranties; refurbished or repaired pumps in old wells are likely to fail again soon. Pulling the well twice is the expensive part.
