How much does it cost to replace a well pump and pressure tank?

Replacing a well pump and pressure tank can cost anywhere from $1,800 to $5,650, with most homeowners spending between $974 and $2,813 on average. Your total cost will depend on several factors, including the type of well pump, the depth of the well, the size of the pressure tank, and installation complexity.

If you’re dealing with low water pressure, inconsistent water supply, or a completely non-functioning well system, it might be time to consider a full replacement of both the pump and the tank.

🧾 Well Pump and Pressure Tank Replacement Cost Breakdown

🔧 Factors That Affect the Total Cost

1. Pump Type

• Shallow Well Jet Pumps: Typically less expensive, ideal for wells 25 feet deep or less.

• Deep Well Submersible Pumps: More costly, but necessary for wells over 25 feet deep.

2. Installation Depth
The deeper the well, the more labor and specialized equipment are needed, driving up the cost significantly.

3. Pump Capacity & Size
Larger pumps with higher gallons-per-minute (GPM) ratings cost more and may require larger tanks or electrical upgrades.

4. Materials and Accessories
Don’t forget about pressure switches, check valves, wiring, control boxes, and booster pumps—these can add hundreds or even thousands of dollars to the final bill.

5. Labor Costs
Professional installation typically costs between $250–$500, but can rise depending on the scope of work, trenching needs, or time required.

6. Site Access
If your well is located in a difficult-to-reach spot or requires excavation, expect higher labor charges.

7. Constant Pressure System Upgrades
Modern upgrades like a constant pressure system offer more consistent water flow, but also increase your investment.

🛠️ DIY vs. Professional Installation

DIY Installation:
Homeowners with plumbing and electrical experience may be able to replace a pressure tank themselves and save on labor. However, working with submersible pumps or complex systems should be left to the professionals.

Professional Installation:
Hiring a licensed well contractor ensures proper installation, code compliance, and peace of mind. For deep wells or when replacing both a pump and pressure tank, professional help is strongly recommended.

💡 Example Costs

• Shallow Well Jet Pump Replacement (Up to 25 ft depth):
  $900 – $2,000 (including labor and tank)

• Deep Well Submersible Pump Replacement (Over 100 ft depth):
  $2,000 – $8,000 (especially with constant pressure systems)

✅ Recommendation

Before you commit to replacing your well pump and pressure tank, it’s wise to:

• Get at least 2–3 estimates from licensed plumbers or well specialists.

• Ask about warranty coverage for both parts and labor.

• Check whether your current electrical system and well casing meet the needs of a new pump system.
