Most US homeowners pay $1,000 to $3,000 for a submersible pump replacement. Shallow jet pumps run $500 to $1,500. Deep wells or complex jobs reach $5,000+.
Submersible Pump Installed
$1,000 - $3,000
Wells 25 to 400 ft
Jet Pump Installed

Cost by Pump Type and Well Depth
Well depth determines pump type. Deeper wells cost more because the old pump must be physically pulled from inside the well casing, requiring more labor and sometimes a boom truck.
| Pump Type | Typical Well | Pump Only | Installed (Typical) | Installed (High) |
|---|---|---|---|---|
| Shallow jet pump | Under 25 ft | $150 - $400 | $500 - $900 | $1,200 |
| Deep jet pump | 25 to 100 ft | $200 - $600 | $700 - $1,500 | $2,000 |
| Submersible (standard) | 25 to 150 ft | $300 - $700 | $1,000 - $2,000 | $2,800 |
| Submersible (deep) | 150 to 400 ft | $500 - $1,500 | $1,500 - $3,500 | $4,500 |
| Submersible (very deep) | 400+ ft | $800 - $2,000 | $2,500 - $5,000 | $7,000+ |
| Constant pressure system | Any depth | $1,500 - $3,000 | $2,300 - $4,500 | $6,000 |

Cost Breakdown: What You Actually Pay For
A well pump replacement involves more than just the pump. Here is a typical 150-foot submersible job itemized.
Pump unit (3/4 HP submersible)
Franklin Electric or Goulds are most common
$400 - $800
Drop pipe (150 ft of 1 inch poly pipe)
Connects pump to surface; $2 to $3.60/ft
$360 - $540
Pump wire (150 ft, 10/3 gauge)
May reuse existing if in good condition
$375 - $600
Labor to pull old pump
2 to 4 hours for a 150 ft well
$300 - $600
Labor to install new pump
Including torque arrestor and safety rope
$200 - $400
Pitless adapter (if replacing)
Replace if corroded; common on wells over 20 years old
$50 - $150
Control box (3-wire pumps only)
Not needed for 2-wire pumps
$150 - $400
Pressure tank (if replacing)
Recommended if tank is over 10 years old
$300 - $600
Well permit (if required)
Required in some counties; see permits by state guide
$0 - $200

Other Factors That Affect Cost
Pressure tank condition
If your pressure tank is over 10 years old, replace it when you replace the pump. A failing tank causes rapid cycling that burns out pumps prematurely. Bundling adds $300 to $600 but saves a future service call.
Pressure tank guide →Pump horsepower
A 1/2 HP pump handles most 2-bedroom homes. 3/4 HP covers 3 to 4 bedrooms. 1 HP or higher for irrigation, livestock, or homes with 3+ simultaneous bathrooms. Each step up adds $100 to $300 to the pump cost.
HP sizing guide →Well depth
Every 100 feet adds roughly $200 to $400 in labor. A 50-foot pull takes 2 to 3 hours. A 300-foot pull is a half-day job requiring heavier equipment or a crane truck.
Cost by depth →Emergency vs planned
Emergency calls add 25 to 50 percent to the total. Planning a proactive replacement when your pump is 12 years old saves $300 to $800 compared to a no-water crisis call.
Emergency premium guide →Electrical work
Submersible pumps need a dedicated 240V circuit. Corroded or undersized wiring adds $200 to $500. A new control box for 3-wire systems adds $150 to $400. Two-wire pumps skip the control box entirely.
Permits and inspection
Some states require a well permit ($50 to $200) for pump replacement. Florida, New Jersey, and Virginia are among the strictest. Water testing after installation is $50 to $150.
