Quick answer: Most sump pumps last 7 to 10 years with regular care. Replacing one usually costs $350 to $1,000 including labor. A home warranty may pay for the pump itself, depending on the plan, but standard home insurance generally does not cover water backup damage unless you add it.
Last updated: October 26, 2026. Figures come from the sources listed at the end and from the plan agreements we have read.
How Long Does a Sump Pump Last?
Angi puts the replacement window at 7 to 10 years with good maintenance. American Family says sump pumps typically last around 10 years. Both agree that how the pump is used matters as much as its age.
What shortens a pump’s life:
- Running often or for long periods, for example in a high water table.
- Rust and corrosion around the motor and float.
- Long idle stretches. A pump that is rarely engaged can wear out sooner.
- Power outages and surges.
- A float that cycles too much, plus debris and clogs.
Repair or Replace: How Long Does a Sump Pump Last by Age
The sources give two clear markers: repair tends to make sense under 5 years, and the replacement window opens at 7 years. They give no firm rule for the years in between, so we mark that band as a judgment call.
| Pump age | What to do | Repair makes sense? |
|---|---|---|
| Under 5 years | Repair the fault. Check the float, the check valve and the power first. | ✓ |
| 5 to 7 years | Test every 3 to 4 months and watch for warning signs. Decide by condition, not by age alone. | Depends |
| 7 to 10 years | Plan to replace. This is the window Angi gives for replacement. | ✗ |
| Over 10 years | Past the typical lifespan. Replace before storm season. | ✗ |
Manufacturer warranties usually run one to three years, so a pump past that point is paid for by you unless another plan applies.
Warning Signs Your Sump Pump Is Near the End of Its Life
- Rust or corrosion at the base, the motor or the float.
- Running nonstop for several minutes at a time.
- Short on and off cycling.
- Noises other than a low hum.
- Excess vibration.
Any one of these on a pump near the end of its range is a reason to test it this week, not next season.
How to Test a Sump Pump in 5 Minutes
Farmers describes a simple bucket test. Do it every few months and before heavy storms.
- Make sure the pump has power. Plug it straight into an outlet, not an extension cord, and test the outlet or GFCI.
- Slowly pour a bucket of water into the pit.
- Check that the float rises and the pump turns on.
- Check that water leaves through the discharge pipe.
- Check that the pump shuts off once the water level drops.
Also look at the discharge line every 3 to 4 months and before winter for debris, kinks and ice. Clean the pit and intake screen twice a year with the pump unplugged. If you have a battery backup, test it as the manufacturer says. Unplug the pump before you touch it, and call a licensed professional for anything electrical.
Why Sump Pumps Fail, and What Each Failure Tells You
Age is only part of the story. HomeServe lists the usual causes of failure during storms, and most of them are checkable before the rain arrives.
| Cause | What happens | What to do |
|---|---|---|
| Power outage | A pump with no battery backup stops exactly when a storm knocks the power out. | Add a battery backup, either a second pump or a standalone battery pump beside the main one. |
| Clogged discharge pipe | Dirt, leaves or rocks block the pipe. Water flows back and the pump can overheat and shut down. | Inspect and clean the discharge line. A drain cover helps keep debris out. |
| Stuck or worn float switch | The float catches on the basin wall or gets blocked, so the pump never starts as water rises. | Fill the pit with water and confirm the float rises and the motor starts. |
| Rust on the impeller or motor | Light rust is normal. Heavy rust can cause overheating and failure. | Look at the pump during your yearly test. Heavy rust is a sign to start budgeting for a replacement. |
| Bent impeller or bad check valve | A loose, bent or dented impeller, or a faulty check valve, causes heavy vibration. | Call a plumber. This is a repair, not a cleaning job. |
| Age | Most pumps last around 10 years, so an old pump fails whatever else you do. | Plan to replace it at about 10 years, sooner if it runs often. |
One point matters for coverage. A worn motor or a failed float switch is the kind of breakdown a plan may pay for. A clogged line, a missing power backup or neglected cleaning is the kind of problem a company can call a maintenance issue, so keep a note of when you test and clean the pump.
How Much Does a Sump Pump Cost?
This Old House, using Fixr and Angi data updated March 2026, gives these ranges. Angi alone puts replacement at $308 to $748, so expect some spread by region.
| Item | Typical cost |
|---|---|
| Replacement, pump and labor | $350 to $1,000 |
| Pump only, pedestal | $80 to $800 |
| Pump only, submersible | $90 to $1,000 |
| Battery for a backup system | $150 to $250 |
| New installation with a basin | About $1,400 on average ($500 to $4,000) |
| Plumber labor | $75 to $150 per hour |
Costs climb when there is no basin yet, when concrete must be drilled ($2,500 to $5,000), or when discharge piping must be buried ($250 to $2,000).
Who Pays When a Sump Pump Fails?
Three different things can pay, and they cover different parts of the problem.
1. A home warranty plan
It depends on the company. This is what we could verify:
| Company | Sump pump | What the source says |
|---|---|---|
| American Home Shield | ✓ | Its plumbing coverage page lists permanently installed sump pumps for ground water only, including the battery if it is used only for the pump. |
| Cinch | ✓ | Its product sheet lists sump pumps under plumbing in the Complete Home plan. It notes that terms, conditions and limitations apply. |
| Choice | Add-on | In the agreement we read, sump pumps are an optional item that costs extra. |
| Select | Add-on | In the agreement we read, sump pumps are an optional item. |
| Old Republic Home Protection | ✓ Covered | This Old House reports the sump pump is covered in all four plans (Essential, Standard, Ultimate, Platinum). Each additional pump is an optional add-on at $60. Trade call fee is $75 to $100, or $100 on Ultimate and Platinum. Plans are sold in 24 states. |
| 2-10 | Not named | The sample we read does not name sump pumps. It excludes outside events such as flood and water damage. |
We list only plans whose terms we verified. Agreements change, so read yours, or run it through our contract decoder. For a similar question about water supply, see our guide on whether a home warranty covers a well pump.
2. Home insurance
Farmers says water backup damage generally is not covered by a standard homeowners policy unless you add water backup coverage, and that problems from wear and tear typically are not covered either. Ask your insurer about a water backup endorsement before storm season, not after.
3. The manufacturer
Manufacturer warranties usually last one to three years, per Angi. Keep the receipt and the model number.
What a plan usually will not pay for
ConsumerAffairs notes that most plans cover sump pump repair and replacement, but the fine print often limits it. These are the common limits to look for in your own agreement:
- Battery backup systems. Sometimes only mechanical failures are covered, and some contracts exclude problems caused by the backup power assembly.
- Water-powered and portable pumps. Portable or non-hard-piped units are generally excluded, and water-powered pumps are less common in coverage.
- Pump location. Some contracts exclude a pump outside the home or in a crawl space.
- Improper installation and lack of maintenance. If the pump failed because it was installed wrongly or never cleaned, a claim can be denied.
- Dollar caps. Plans have a coverage limit. You pay anything above it, plus the service call fee.
- Pump age. Some companies exclude pumps over a certain age.
- Manufacturer warranty. If the pump is still under its own warranty, the plan may not pay for the same repair.
The flooding itself is a separate matter. A plan pays for the pump, not for the wet carpet, drywall or stored belongings. That is where the water backup add-on to home insurance comes in. If your claim is turned down, our claim denied letter tool can help you write the appeal.
A simple yearly schedule
| When | What to do |
|---|---|
| Every quarter | Unplug the pump, open the lid and remove dirt, sand, mud or debris from the pit and pump. HomeServe recommends this quarterly cleaning. |
| Before the rainy season | Run the full bucket test, confirm the float rises, and check the discharge line is clear. |
| After a long outage or heavy storm | Check the battery backup and test the pump again. |
| At about 10 years | Start planning a replacement, before it fails during a storm. |
Before You Buy a Plan Just for the Pump
- Check the limit and the waiting period. A plan that starts after a delay will not help during this month’s storm. See our guide to the waiting period.
- Watch for pre-existing conditions. Many contracts exclude problems that existed before coverage began. A pump already near the end of its life is a risk. Read our guide to pre-existing condition clauses.
- Compare more than the pump. A pump is one item. See how plans compare overall in our ranking of home warranty companies.
Sump Pump Questions Answered
How often should a sump pump be replaced?
Plan for every 7 to 10 years, sooner if it runs constantly, rusts or cycles short.
How do I know if my sump pump is working?
Do the bucket test above: the float rises, the pump starts, water leaves the discharge pipe, and the pump stops when the level drops.
Does home insurance cover a sump pump failure?
Generally not for wear and tear, and not for water backup unless you added that coverage.
Does a home warranty cover water damage after the pump fails?
A plan that covers the pump pays for the pump. It is not a flood policy. In the 2-10 agreement we read, flood and water damage are excluded events, so check how your own plan treats damage to the house and belongings.
The Bottom Line: How Long Does a Sump Pump Last?
A sump pump is a 7 to 10 year part. Test it every few months, replace it at the end of that window, and know before the storm who pays: your plan, your insurer or you. Some plans cover it, some sell it as an add-on, and standard insurance usually leaves out water backup.
