How Much Does a Sump Pump Replacement Cost?
There are three main categories of sump pumps, each with different price points:
Pedestal Sump Pumps
Unit Cost: $150 – $400
Pedestal pumps sit above the sump pit. They represent the most affordable type but offer less pumping capacity than submersible models.
Benefits:
- Low purchase price
- Easy to inspect and maintain
- Quiet operation
Limitations:
- Limited pumping power
- Prone to overheating
- Higher risk of failure
Submersible Sump Pumps
Unit Cost: $200 – $600
Submersible pumps install inside the sump pit. They provide the most power and efficiency, but have a higher equipment cost.
Benefits:
- Strong pumping capacity
- Energy efficient
- Run quietly
Considerations:
- Higher equipment cost
- Difficult to inspect or repair
- Can clog with sediment over time
Battery Backup Sump Pumps
System Cost: $1,000 – $2,500 installed
Battery backups provide protection against power outages or primary pump failures. Complete installed systems typically range from $1,000-$2,500.
Benefits:
- Protection during outages
- Redundancy if main pump fails
- Peace of mind
Considerations:
- High cost for equipment and installation
- Batteries require replacement every 3-5 years
According to Angi, the typical cost for replacing a sump pump is around $524, with a range between $308 and $749. The total cost can vary based on the type of sump pump chosen and the company hired for the replacement.
As noted by Carter’s My Plumber, homeowners can expect to pay between $800 and $1,600 for sump pump replacement. This estimate includes factors such as the type of pump and labor costs, which can vary by location and the plumber’s experience.
According to HomeAdvisor, installation costs typically fall between $642 and $2,095, with an average cost of about $1,345. The article emphasizes that pedestal sump pumps generally cost between $60 and $170, while submersible pumps range from $100 to $400.
In an overview by Summers Plumbing Heating & Cooling, they report that replacement costs can range from $100 to $300 for the unit itself, depending on whether you choose a pedestal or submersible model. They also highlight additional costs for labor, which can range from $50 to $200 per hour.
Lastly, according to another article on Angi, installing a new sump pump typically costs between $1,200 and $2,500, with an average of around $1,500. The article notes that installation complexity and location within the home can significantly influence these costs.
Factors Affecting the Cost
Several variables influence the full investment required:
Type of Sump Pump
More powerful and complex pumps naturally cost more.
- Basic pedestal unit: $150-$400
- Heavy-duty submersible: $400-$700
- Full backup system: $1,000-$2,500
Labor and Installation Costs
A professional sump pump installation or replacement averages $500 – $1,200 in labor, depending on complexity. alterations needed, and local rates.
Required Sump Pump Capacity
Larger homes or those with a high water table may require heavy-duty pumps sized for higher volumes of water. Over-speccing capacity increases costs.
Extent of Additional Modifications
Modifying the sump pit dimensions, rerouting discharge drainage, or installing an entirely new drainage system adds cost.
Special Features
Adding monitoring systems, alarms, or automation functionality increases parts and installation costs $50-$500+ depending on features.

Costs Based on Home Size
Here are typical cost ranges for common sized homes:
Small Homes (600 – 1,000 sq ft) – $400 – $1,000 parts and labor for a basic pedestal or submersible sump pump.
Mid-Sized Homes (1,000 – 2,000 sq ft) – $700 – $1,500 parts and labor for a more powerful submersible pump, potentially with backup features or re-routing of discharge drainage.
Large Homes (2,000 – 3,000+ sq ft) – $1,200 – $3,000 parts and labor for a high-capacity submersible pump, backup system, and extensive modifications to pit, drainage, and electrical as needed.
Homes prone to severe flooding may warrant investment in more robust pump systems and backups.
Professional vs. DIY Installation
For most homeowners, hiring a professional for sump pump replacement is worth the cost:
Professional Replacement Cost: $1,000 – $3,000
Includes unit, full installation, and any modifications.
Benefits of Professional Installation:
- Expert diagnosis of any issues affecting performance
- Ensuring properly sized pump for your home’s specific needs
- Correct wiring and plumbing modifications
- Meeting any local codes and permit requirements
- Warranty protection on labor
DIY Replacement Cost: $200 – $500 for pump unit only
Labor, extras, and modifications not included.
DIY sump pump replacement is possible but risky for non-experts:
The Challenges of DIY Installation:
- Identifying and correctly fixing underlying issues
- Obtaining proper permits
- Disposing old pump safely
- No professional equipment or expertise
For most homeowners, the benefits of hiring a pro outweigh taking on replacement yourself unless you have extensive plumbing, electrical, and sump pump system knowledge.
Additional Costs
- Sump pit replacement or liner: $200 – $2,000
- Battery backup system: $500 – $1,500
- Check valve: $50 – $150 parts + $50-$100 labor
- New discharge line: $100 – $300 parts + $100-$200 labor
- Annual maintenance: $100 – $300 per year
Take the replacement opportunity to inspect and upgrade related components that impact functionality and lifespan.
How Long Should a Sump Pump Last?
When maintained properly:
- Standard sump pumps last 7-10 years
- Backup battery systems last 3-5 years
- Heavy-use pumps may last only 3-5 years
Signs that replacement is needed:
- Frequent on/off cycling
- Loud noises or grinding
- Reduced pumping capacity
- Rust or cracks
- Musty or burning smell
Well maintained pumps can provide 10+ years of service. But inadequate upkeep shortens runtimes. Know your pump’s maintenance history and plan replacement accordingly.

Answers to Common Questions
How much does it cost to replace a sump pump on average?
For a typical home, expect to budget $1,000 – $2,000 for the pump, labor, and minor modifications. Larger homes or extensive installations run higher.
Should I install a battery backup sump pump?
For protection against power outages and pump failures, battery backup systems are recommended. But at $1,000 – $2,500 installed, they represent a significant investment.
Can I replace a sump pump myself?
With expertise in plumbing, electrical, and sump systems, DIY replacement is possible. But for most, hiring a pro to ensure proper installation and address surrounding issues is worth the cost.
Table of Cost Ranges for Sump Pump Replacement
Type | Unit Cost Range | Installed System Cost Range |
---|---|---|
Pedestal Pump | $150 – $400 | $700 – $1,000 |
Submersible Pump | $200 – $600 | $1,000 – $2,000 |
Battery Backup System | $500 – $1,500 | $1,500 – $2,500 |
Is Repairing an Old Sump Pump Worthwhile?
Minor repairs can sometimes extend an aging pump’s service life at a reasonable cost. But once major issues develop, replacement becomes the better investment:
Worthwhile minor repairs:
- Clearing dirt/debris clogs: $50 – $150
- Replacing worn gasket seals: $15 – $40
- Tightening fittings: $10 – $25 in parts
Better to replace pump entirely:
- Failing motor: $150+ parts
- Severe corrosion/damage: $200+ in repairs
- Reduced pumping capacity
Compare repair costs to a new pump’s $500 – $1,500 price. Once vital components show wear, repairs simply buy a little extra time before failure. Replacement provides superior protection.
