Why a Working Sump Pump is Critical for Your Home
When your sump pump not working becomes a reality, you're facing a potential basement flooding disaster that could cost thousands in water damage repairs.
Quick troubleshooting steps for a non-working sump pump:
- Check power - Ensure it's plugged in and circuit breaker isn't tripped
- Test the float switch - Manually lift it to see if pump activates
- Clear debris - Remove any objects blocking the float or intake screen
- Inspect discharge line - Look for clogs or frozen pipes
- Listen for sounds - Humming without pumping indicates internal blockage
Your sump pump sits in the lowest part of your basement, quietly protecting your home from groundwater that could otherwise flood your living space. Most sump pumps last between seven and 10 years, but they can fail without warning - especially during storms when you need them most.
The good news? Many sump pump problems are surprisingly simple to fix yourself. Before calling a professional, you can often get your pump running again with basic troubleshooting steps that take just minutes to complete.
Understanding how to diagnose and fix common sump pump issues can save you hundreds of dollars in emergency repair calls. More importantly, it can prevent the devastating water damage that occurs when basements flood during heavy rains or rapid snowmelt.
First Response: What to Do When Your Sump Pump Fails During a Storm
When a storm hits and you find your sump pump has failed, it's crucial to act fast. Don't panic—these immediate steps can help you minimize damage and get the situation under control.
Safety First, Always!Before you do anything else, prioritize safety. If you have any standing water in your basement, immediately unplug any electronics in the flooded area. Water and electricity are a dangerous mix, and we want to avoid any shocks or further hazards.
Move Valuables to Higher GroundOnce the electrical situation is secure, act quickly to move any stored items like furniture, rugs, or boxes to a dry area. Every minute counts when water is rising, and getting your belongings out of harm's way can prevent irreparable damage.
Manual Water RemovalYour sump pump's job is to remove water, but when it's out of commission, it's time for you to step in.
- Buckets and Mops: For small amounts of water, this classic method is effective.
- Wet/Dry Vacuum: A wet/dry vacuum is excellent for removing water. Ensure it's rated for wet use and that electrical outlets are safe.
- Hand Pump: During a power outage, a hand pump with a garden hose can manually remove water from the sump pit.
- Trash-Water Pump: For serious flooding with debris, a heavy-duty trash-water pump can remove thousands of gallons per hour.
As you remove water, make sure to deposit it at least 20 feet away from your house to prevent it from seeping right back into your foundation. Once the water is removed, use fans and dehumidifiers to thoroughly dry out the basement. If the storm has settled, opening windows can also help with air circulation.
While these DIY steps can help in an emergency, a persistent issue often points to a larger problem. For a deeper dive into when to call in the pros, check out our guide on Signs Your Sump Pump Needs Professional Repairs.
Your Sump Pump Not Working? A Step-by-Step Troubleshooting Guide
When your sump pump not working situation hits, there could be several reasons. The good news is that most problems have straightforward solutions you can tackle yourself. Let's walk through the most common culprits, from simple fixes to trickier issues.
Troubleshooting a Sump Pump Not Working Due to Power Issues
Many sump pump issues are simple power problems. Before assuming the worst, check these basics.
Ensure the pump is plugged in. Vibrations can work the plug loose over time.
Check the circuit breaker. A pump's power surge can trip it. Flip the breaker completely OFF, then back ON.
Check the GFCI outlet. If the "RESET" button on this safety outlet has popped out, press it back in. These can trip from the pump's power surge.
Test the outlet itself with a lamp or charger to confirm it has power. If not, the problem is with the electrical supply, not the pump.
Confirm there isn't a power outage in your area, as this will stop your electric pump from working.
If these power checks don't solve your problem, it's time to dig deeper into mechanical issues.
The Float Switch: The Most Common Point of Failure
The float switch tells the pump when to turn on and off as water levels rise and fall. It's the most likely component to cause problems when your sump pump not working properly.
Debris can jam the float switch, preventing it from moving. If it gets stuck in the down position, your pump won't turn on. If it's stuck up, your pump will run continuously and overheat. To fix this, unplug your pump for safety, then clear any debris from the pit. Manually lift the float to ensure it moves smoothly.
The float switch cord can get tangled around the pump. Unplug the pump first, then gently untangle the cord so it can operate freely.
Pump vibration can shift the unit, wedging the float against the pit wall. Unplug the pump and reposition it in the center of the pit with plenty of clearance.
The float sensor itself can fail. Even if it's not stuck, the internal mechanism might be broken. You can test this by pouring water into the pit to see if the float lifts and activates the pump.
What to Do When Your Sump Pump is Not Working but Making Noise
If you hear your pump humming but the water level isn't going down, it's likely a blockage.
A clogged intake screen at the pump's base can block water from entering. Unplug the pump, lift it out of the pit, and clean the screen. Also, remove any mud or debris from the pit itself.
A jammed impeller inside the pump can also cause humming. The impeller is the spinning part that moves water, and small debris can jam it. You'll need to unplug the pump and remove the bottom housing to access and clear it.
Your discharge line might be the problem. This pipe carries water out of your house and can get blocked by ice, leaves, or other debris. Check where it exits your home and clear any visible blockages.
If you've tried these solutions and your pump is still making noise without moving water, it might be time to call in professional help. For more guidance on when to seek expert assistance, check out our resource on Sump Pump Repair to Prevent Flooding.
Pump Runs Constantly or Shuts Off Too Soon
A pump that runs constantly or cycles on and off every few minutes (short-cycling) is headed for an early breakdown and leaves you vulnerable to flooding.
A faulty check valve is a common cause. This one-way valve in your discharge line prevents water from flowing back into the pit. If it fails, water returns, causing the pump to cycle again. The valve may need to be replaced.
Incorrect float switch adjustment can also cause erratic behavior. If the on/off range is too narrow, the pump will short-cycle. Check your owner's manual for adjustment instructions.
An undersized pump or pit can be overwhelmed by the volume of water, causing it to run constantly. This situation may require a professional assessment to determine if you need a larger capacity pump or pit.

Prevention: Maintenance, Backups, and Replacement
Proactive maintenance is the best way to prevent your sump pump not working when you need it most. These simple tasks can save you thousands in water damage repairs down the road.
Essential Sump Pump Maintenance Checklist
Regular attention will keep your sump pump serving you faithfully for years.
- Monthly Testing: Pour about five gallons of water into the sump pit. The pump should activate, remove the water, and shut off. This helps you catch problems early.
- Quarterly Cleaning: Unplug the pump and clean debris from the pit. Check that the float switch moves freely without sticking.
- Discharge Pipe Check: Also quarterly, check the exterior discharge pipe opening and clear any leaves, dirt, or ice that might be blocking it.
- Seasonal Deep Cleaning: Remove the pump from the pit and clean the inlet screen at the bottom to ensure it's not clogged.
- Annual Professional Inspection: We strongly recommend an annual professional inspection for deeper checks and to spot potential issues before they become emergencies. For comprehensive service in the Springfield area, our Sump Pump Repair Springfield IL team is ready to help.
Backup Systems for Ultimate Peace of Mind
Power outages often happen during major storms, disabling your electric pump. A backup system is essential for protection during these times, as even a few hours without a working pump can lead to flooding.
Battery backup systems include a secondary pump powered by a deep-cycle battery that automatically activates when power fails. They can provide several hours of pumping power.
Generator options offer more flexibility. A portable generator requires manual setup but can power your pump and other appliances. A whole-home generator switches on automatically and can run for days.
Here's how these options stack up:
| Feature | Battery Backup | Generator |
|---|---|---|
| Activation | Automatic | Portable: Manual / Whole-home: Automatic |
| Run Time | Hours (battery dependent) | Days (fuel dependent) |
| Installation | Simple, often DIY-friendly | Complex, usually needs professional |
| Best For | Short outages, pump failures | Extended outages, multiple systems |
The peace of mind from a backup system is invaluable. Learn more about why these systems are so important at Why you need a backup battery system.
Knowing When to Replace Your Sump Pump
Sump pumps typically last seven to 10 years. Recognizing the signs of failure helps you replace it proactively, not during a crisis.
- Excessive Noise: Grinding, rattling, or gurgling sounds often indicate wearing internal components like bearings or the motor.
- Frequent Cycling: Turning on and off too often can indicate a faulty check valve or a failing pump that's struggling to keep up.
- Visible Rust: While minor rust is normal, extensive corrosion can signal internal deterioration.
- Runs Constantly: If the pump runs non-stop despite troubleshooting, its motor may be losing efficiency or it may be undersized for your needs.
- Age: If your pump is over 10 years old, consider replacing it proactively. The risk of your sump pump not working increases dramatically with age.
The decision between repairing and replacing often comes down to cost. Minor repairs on a newer pump are usually worth it, but if you're facing major repairs on an older unit, replacement is often the smarter, more reliable choice.
