If you know what to look for, you can:
- Catch the problem early
- Save thousands in water damage

Common Causes of Sump Pump Failure
Sump pumps fail for a handful of very predictable reasons.
The best news? If you know the most frequent causes of failure, pinpointing the issue is simple. The National Association of Home Builders found that improper care contributes to 60% of sump pump failures in their 2023 study. Another 25% can be attributed to power.
That means most failures are preventable.
If you’re looking for sump pump installation repair in the Midwest, calling a sump pump repair Indianapolis professional is the best decision you’ll make all day. Having a professional perform a correct sump pump diagnosis can keep you from spending thousands on water damage and emergency service calls.
Here are the top reasons sump pumps fail:
- Power outages: If there is no power, you have no pump. They always go out when it storms.
- Stuck float switch: Debris jams the switch and the pump can’t sense water
- Clogged discharge line: Water has nowhere to go
- Old age: Most pumps last 7-10 years
- Incorrect size: When pumps are undersized they struggle to produce water volume
- Frozen pipes: A frozen discharge line backs water right into the pit
Pretty straightforward, right?
However… each of these issues has warning signs. Spot them in time, and you can prevent a world of hurt (and expense) dealing with a flooded basement.
How to Diagnose Sump Pump Problems
Diagnosing your sump pump isn’t as complicated as you might think.
All you have to do is know what to look for. Problems will generally present themselves with one of these symptoms:
Strange Noises
A properly working sump pump should not make loud noises. If your pump is doing any of the following, something is amiss:
- Grinding noises: The impeller is damaged or jammed
- Rattling: A bent or broken impeller
- Gurgling: Issues with the check valve
- Constant humming: The motor is running but the pump isn’t moving water
The solution? Most of these problems can be resolved with part replacement. This may be an easy DIY task for some homeowners.
Pump Runs Constantly
If your pump never stops running… You have a problem.
A pump that runs nonstop will burn out fast. This usually points to:
- A stuck float switch
- A check valve that isn’t working properly
- A pump too small for your home
- Groundwater overwhelming the system
Reach inside and see if the float can move freely. It may just be jammed against the side of the pit.
Pump Won’t Turn On
This is the most obvious (and most frustrating) sign of failure.
Make sure the pump is plugged in. No, seriously. Plugs come loose all the time. Then try plugging something else into the outlet. You might have blown a fuse.
If both are fine, the issue is likely:
- A burned out motor
- A broken float switch
- Faulty wiring
Visible Rust or Corrosion
Look at your pump. If there is substantial rust or corrosion, your pump has had it. Iron bacteria can inflict this damage and drastically reduce the life of your pump.
Quick Fixes You Can Do Yourself
Some sump pump problems have super simple fixes.
Before calling a pro, try these basic troubleshooting steps:
Step 1: Make sure the pump works. Fill the pit with a bucket of water. The pump should come on and suck up the water. If not, you have identified the issue.
Step 2: Clean the pit. Make sure the pump is unplugged. Remove debris, rocks, or sediment from the pit. Buildup is the number one cause of failure.
Step 3: Test the float switch. Ensure the float moves up and down freely. If stuck, liberate it gently and retest pump.
Step 4: Examine the discharge line. Go outside and locate the area where the discharge pipe exits your home. Check for obstructions, ice, or damage. Remove any clogs that restrict water flow.
Step 5: Test the check valve. This valve keeps water from running backwards into the pit. If water still sounds like it’s flowing after the pump turns off, you need to replace this valve.
These simple tests solve majority of sump pump issues… Never have to call a professional again.
When to Call a Professional
Some sump pump issues are beyond a DIY fix.
If you have attempted the above steps and your pump still will not operate, seek professional assistance. The average cost to homeowners for cleaning up a flooded basement ranges between $2,000 and $7,000, making the typical $400 professional repair bill much more affordable than the alternative.
Call a professional if you notice:
- Burning smell: The motor is overheating
- Electrical issues: Sparks, tripped breakers, or shocks
- Major mechanical failure: The pump won’t run at all
- Pump is 10+ years old: Replacement is often cheaper than repair
- Water already in the basement: Don’t wait, get help fast
Here’s something most homeowners don’t realize…
There is a 26% chance of flood damage in a 30 year mortgage. Compare that to only a 9% chance of fire damage. Mold will also start growing 48 hours after water exposure.
Don’t be that homeowner.
Having your sump pump inspected by a professional once per year can help identify minor problems before they become costly repairs. A professional can also identify problems you may not notice such as:
- Improper pit sizing
- Discharge line grading problems
- Backup pump readiness
- Foundation crack issues
Preventing Future Sump Pump Failures
Prevention is way easier than repair.
Create a simple maintenance schedule and you will eliminate failures. Here is your schedule:
Every 3 months:
- Test the pump with a bucket of water
- Clean debris from the pit
- Check the discharge line for blockages
Every year:
- Inspect for rust and wear
- Clean the inlet screen
- Check the backup pump (if you have one)
- Schedule a professional inspection
Every 7-10 years:
- Replace the entire pump
It takes less than an hour per year to do this simple routine. It could save you thousands in flood damage.
Final Thoughts
Sump pump failure isn’t a question of “if”… It’s a question of “when”.
The good news is that most failures can be identified early, if you know what you’re looking for. Here’s a quick review:
- Learn the common causes of failure
- Watch and listen for warning signs
- Try basic DIY troubleshooting first
- Call a pro for major issues
- Build a simple maintenance routine
Wait until water is standing in your basement before panicking. Prevention costs WAY less than cleanup.
Your basement (and your wallet) will be way better off for it.
