Well Pump Replacement Cost: Complete 2026 Price Guide
No water coming from your well? A failed pump is often the culprit—and yes, it's an emergency. The good news: replacing a well pump is much cheaper than drilling a new well. California homeowners typically pay $1,200 to $4,500 for a complete pump replacement, with the biggest cost driver being how deep your well is. Here's exactly what you'll pay.
💵 Quick Price Summary
- • Submersible pump (most common): $1,500 - $4,500
- • Jet pump (shallow wells): $800 - $1,600
- • Pump alone: $400 - $2,500
- • Labor adds: $500 - $2,000+ (depth dependent)
Well Pump Replacement Cost Overview
The total cost to replace a well pump depends on three main factors: the type of pump you need, how deep your well is, and the labor required for installation. Here's a quick overview of what California homeowners can expect in 2026:
📊 Typical Well Pump Replacement Costs
Shallow Well Jet Pump
0-25 ft depth
$800 - $1,600
Deep Well Jet Pump
25-100 ft depth
$1,000 - $2,200
Submersible Pump ⭐ Most Common
100-300 ft depth
$1,500 - $3,500
Deep Submersible Pump
300-500 ft depth
$2,500 - $4,500
Very Deep Wells
500+ ft depth
$4,000 - $6,500+
*Prices include pump, labor, and standard parts
These ranges represent complete professional installations. If you're getting quotes that seem unusually low, make sure they include all components—some contractors quote pump cost only and add labor and parts separately.
Submersible Pump Costs: $800-$2,500
Submersible pumps are the most common type for California wells, especially in San Diego County where well depths typically range from 200 to 600 feet. These pumps sit at the bottom of your well, submerged in the water, and push water up to the surface.
Submersible Pump Equipment Costs
The pump itself is a significant portion of your total cost. Prices vary based on horsepower, quality, and depth rating:
| Pump Size | Best For | Equipment Cost |
|---|---|---|
| 1/2 HP | Small homes, shallow wells (under 150 ft) | $400 - $800 |
| 3/4 HP | Average homes, moderate depth (150-250 ft) | $600 - $1,200 |
| 1 HP | Larger homes, deeper wells (250-400 ft) | $800 - $1,500 |
| 1.5 HP | High demand, deep wells (350-500 ft) | $1,000 - $1,800 |
| 2+ HP | Agricultural, very deep wells (500+ ft) | $1,400 - $2,500 |
We typically recommend quality brands like Grundfos, Franklin Electric, or Goulds for California installations. While budget pumps exist, the cost difference is often minimal compared to the labor—and a quality pump can last 12-15 years versus 6-8 for cheaper alternatives.
Why Submersible Pump Labor Costs Add Up
Labor is where submersible pump replacement gets expensive—and for good reason. Replacing a pump at the bottom of a 400-foot well is significantly more complex than most plumbing work:
- Pulling the old pump: The pump, pipe, and water inside can weigh 300-500+ pounds. Specialized equipment is required.
- Inspecting the well: While the pump is out, we inspect casing condition and check for problems.
- Installing new pump: Careful lowering to precise depth with proper electrical connections.
- Testing and adjustment: Setting pressure switch, checking flow rate, ensuring proper operation.
👷 Labor Costs by Well Depth
Deep wells require specialized equipment to pull hundreds of feet of pipe
Most San Diego County wells fall in the 300-500 foot range, which is why total replacement costs often run $2,500-$4,500. Learn more about typical well depths in San Diego to estimate what your replacement might cost.
Jet Pump Costs: $400-$1,200
Jet pumps are less common in Southern California but are used for shallower wells and some older installations. Unlike submersible pumps, jet pumps sit above ground (typically in a well house or pump house) and use suction to draw water up.
Shallow Well Jet Pumps
Shallow well jet pumps work for wells where water level is within 25 feet of the surface. These are the least expensive pumps to replace:
- Pump cost: $200 - $500
- Labor: $200 - $400
- Total replacement: $400 - $900
Deep Well Jet Pumps
Deep well jet pumps (also called convertible jet pumps) can lift water from depths up to 90-100 feet using a two-pipe system:
- Pump cost: $300 - $700
- Labor: $300 - $600
- Total replacement: $600 - $1,300
While jet pumps cost less upfront, they're generally less efficient than submersible pumps and have shorter lifespans. For wells deeper than 100 feet, submersible pumps are the only practical option. Visit our well pump services page to learn more about pump options for your well.
Additional Costs to Consider
Beyond the pump and basic labor, several additional components may need replacement or upgrade during a pump job:
Pressure Tank Replacement
Your pressure tank works hand-in-hand with the pump. If your tank is waterlogged, undersized, or failing, replacing it during pump replacement saves a future service call:
- 20-gallon tank: $150 - $250 installed
- 40-gallon tank: $250 - $400 installed
- 80-gallon tank: $400 - $600 installed
A properly sized pressure tank reduces pump cycling, extending pump life. We often recommend upgrading to a larger tank during replacement.
Electrical Components
Pump electrical systems sometimes need updating:
- Pressure switch: $50 - $150
- Control box (submersible pumps): $100 - $300
- Wiring upgrade: $100 - $400
- Lightning/surge protection: $75 - $200
Well Components
While the pump is out, it's the ideal time to address other well issues:
- Pitless adapter: $150 - $350
- Check valve: $50 - $150
- Torque arrestor: $30 - $80
- Drop pipe (per foot): $3 - $8
Factors That Affect Well Pump Replacement Cost
Understanding what drives costs helps you evaluate quotes and budget accurately:
1. Well Depth
The single biggest factor. Every additional 100 feet of depth adds $300-$500 to your total cost through increased labor, more pipe, heavier pump requirements, and longer wire runs.
2. Pump Type and Size
Higher horsepower pumps cost more but may be necessary for deep wells, high water demand, or long horizontal runs to your home. Undersizing a pump leads to pressure problems and premature failure.
3. Access Conditions
Easy access to your wellhead keeps costs down. Factors that can increase labor cost:
- Wellhead in tight space or building
- Long distance from driveway
- Steep terrain or difficult ground
- Overgrown vegetation around well
4. Emergency vs. Scheduled Service
Weekend, holiday, or after-hours emergency service typically costs 25-50% more than scheduled weekday appointments. If your pump is showing warning signs, scheduling service proactively saves money.
5. Additional Repairs Needed
Sometimes a pump failure reveals other issues—corroded pipe, damaged wiring, or well casing problems. A reputable contractor will discuss any findings before proceeding with additional work.
When to Repair vs. Replace Your Well Pump
Not every pump problem requires replacement. Here's how to decide:
Consider Repair When:
- Pump is less than 5 years old
- Problem is with above-ground components (pressure switch, control box, pressure tank)
- Issue is electrical wiring, not the pump itself
- Repair cost is less than 30-40% of replacement cost
Replace When:
- Pump is over 10-12 years old
- You've had multiple repairs in recent years
- Flow rate has significantly decreased
- Pump runs constantly or cycles rapidly
- Motor is making unusual noises or overheating
- Repair quote exceeds 50% of replacement cost
Pro Tip: Know Your Pump's Age
If you don't know when your pump was installed, the nameplate on the control box or pressure tank often has a date code. We can also look up installation records in county well logs. Knowing your pump's age helps make better repair vs. replace decisions.
Warning Signs Your Pump Needs Attention
Catching pump problems early can prevent complete failure and water outage. Watch for these warning signs:
- Sputtering faucets: Air in lines often indicates pump is drawing air or losing prime
- Reduced water pressure: Pump may be wearing out or well water level dropping
- Higher electric bills: Failing pump motors draw more power
- Pump runs constantly: Could indicate leak, failing pump, or pressure tank issues
- Frequent cycling: Pump turning on and off rapidly shortens lifespan
- Dirty or sandy water: May indicate pump is set too low or screen is failing
- Strange noises: Clicking, grinding, or humming from control box or well
If you notice any of these issues, schedule a well inspection before complete failure occurs. Many problems caught early can be repaired rather than requiring full replacement.
How to Get the Best Value on Pump Replacement
Here's how to ensure you get quality work at a fair price:
Get Multiple Quotes
For non-emergency replacement, get 2-3 quotes from licensed well contractors. Be wary of quotes significantly lower than others—they may use inferior pumps or cut corners.
Ask for Itemized Pricing
A detailed quote should show:
- Pump brand, model, and horsepower
- Labor cost
- Additional parts (pipe, wire, fittings)
- Any other recommended work
- Warranty information
Verify Licensing and Insurance
In California, well pump work should be done by a licensed C-57 (Well Drilling) contractor. Verify licensing at the California Contractors State License Board.
Ask About Warranties
Quality pumps come with manufacturer warranties (typically 1-5 years). Ask about both product warranty and workmanship guarantee. We provide warranty coverage on both parts and labor for your peace of mind.
Frequently Asked Questions
How much does it cost to replace a well pump?
Well pump replacement typically costs $1,200-$4,500 total, including parts and labor. Submersible pumps for deep wells (200-400 ft) cost $800-$2,500 for the pump alone, plus $500-$2,000 for labor. Jet pumps for shallow wells cost $400-$1,200 for equipment plus installation.
How long does a well pump last?
A quality submersible well pump typically lasts 8-15 years, while jet pumps last 4-10 years. Lifespan depends on water quality, pump quality, cycling frequency, and proper sizing. Pumps that cycle frequently due to undersized pressure tanks wear out faster.
Should I repair or replace my well pump?
Replace your pump if it's over 10 years old, requires repeated repairs, has significantly reduced flow, or repair costs exceed 50% of replacement cost. Repair makes sense for newer pumps with minor issues like faulty pressure switches or check valves.
Why is my well pump replacement quote so expensive?
Deep wells require expensive submersible pumps and significant labor to pull hundreds of feet of pipe. A 400-foot well might require $1,500+ in labor just to extract and reinstall the pump. Always get itemized quotes showing pump cost, labor, and any additional parts needed.
Can I replace my well pump myself?
Jet pumps in well houses can be DIY-replaced by handy homeowners. However, submersible pumps in deep wells require specialized equipment to pull hundreds of feet of pipe safely. The pump, pipe, and water can weigh several hundred pounds. Professional installation is strongly recommended for submersible pumps.
