11 Most Common Sump Pump Problems and Solutions

Knowing what’s wrong with your sump pump matters. But identifying and fixing the problem is even more important.

1. Power Failure

Since sump pumps rely on electricity to function, a storm could knock your pump offline. To prevent this from happening, install a generator or a battery backup system and test it at least once a year.

2. Overwhelmed Sump Pump

Your sump pump may not be able to handle heavy rainfall or it may simply be too small. Upgrade to a higher-capacity unit that’s powerful enough to handle the volume of water coming into your basement.

3. Wrong-Size Pump Installed

An undersized sump pump can burn out from being overworked. On the other hand, an oversized unit can short cycle. Talk to a professional plumber to get the right-sized sump pump for your home.

4. Improper Installation

If your sump pump was installed in the wrong location or the discharge pipe is not sloped downward properly, the pump may not be able to protect your home against high water levels. T

here may also be a missing check valve. To ensure your system works effectively, have a licensed plumber install your sump pump.

5. Clogged Sump Pit

Dirt, gravel, or debris can block your intake screen, preventing water from reaching the sump pit. To prevent clogs, clean your pit regularly and install an air-tight sump pit lid.

6. Clogged or Frozen Discharge Line

Clogs in your discharge line can stop water flow and force it back into your home. To fix the problem, clear out any debris and melt the ice with hot water. Then insulate the discharge line and install IceGuard to prevent future freezing.

7. Float Switch Issues

The float switch tells the sump pump when to turn on. If it’s stuck, misaligned, or broken, it can’t do its job. You can either adjust the switch by removing any debris around it or replace it.

8. Pump Running Non-Stop

Your sump pump may run non-stop if you’re experiencing a high water table or heavy rainfall, you have a faulty switch that’s stuck in the “on” position, or there’s a broken check valve that’s preventing water from flowing back into the sump pit. You can resolve the problem by replacing any faulty parts and adding a secondary pump, if needed.

9. Loud Noises or Vibrations

If you’re hearing loud noises or noticing vibrations, you probably have worn-out motor bearings or debris blocking your impeller. Firstly, clean your impeller. If the problem persists, schedule repair or replacement services.

10. Pump Burnout

Pump burnout happens when your sump pump runs too often or is continuously forced to work hard by pumping dirty water. To resolve the issue, keep the pit clean. If the issue continues, your sump pump may be too small. Have licensed plumbers install the correct capacity pump.

11. No Water in Sump Pit

If no water is reaching your sump pit, you probably have a clogged or damaged drainage system. Alternatively, it may not be connected properly. Call a professional to inspect and repair your drain tile system.

How to Prevent Sump Pump Problems

If you want a reliable and efficient sump pump, regular inspections and tests are a must. Here are a few steps you can take to prevent problems before they start.

Routine Maintenance Tips

• Test your pump monthly with a bucket of water. Make sure the float switch turns on and discharges the water properly.
• Clear any debris from the pit and discharge line to prevent future clogs.
• Make sure the float switch and check valve are functioning properly and are not blocked by debris.

Long-Term Protection

• Install a backup pump or a secondary system for additional protection.
• Schedule an annual inspection with licensed plumbers to ensure your sump pump is working effectively.
• Install a battery-powered or water-powered backup in case there’s a power outage.

When to Call a Professional

If you have constant repair issues or your sump pump is cycling too often, call a professional plumber. Flooding, electrical issues, or sewage smells are other red flags that something is wrong with your pump.

Scheduling a service with a licensed plumber comes with important benefits. Plumbers can pinpoint issues with a camera inspection, they can redesign or reinstall your system if it’s working ineffectively, and they can offer tips and permanent solutions to recurring problems.

FAQs About Sump Pump Problems

Homeowners often have questions about their sump pumps. Here are common questions we hear.

How do I know if my sump pump is failing?

If your sump pump doesn’t activate when you pour water into it, it’s a clear sign it’s failing. Other signs include strange noises, visible rust, and running constantly without actually pumping any water.

How long should a sump pump last?

If you’re consistent with maintenance services, your sump pump should last 7-10 years with average use. However, if your sump pump runs frequently and is not well maintained, expect to see a shorter lifespan.

Should a sump pump run all the time?

No, a sump pump should not run all the time. It should only run when there’s enough water to trigger its float switch. It should turn off when the water level is low again.

Can I fix a sump pump myself?

While you can perform minor fixes yourself, like clearing out clogs and replacing a check valve, you should leave more complex issues to licensed plumbers.
