A sump pump is a critical component of your home’s waterproofing system, and in many cases, it runs continuously to address rising water levels. Over time, your sump pump can start making odd noises, fail to activate during a rainstorm, or stop working altogether due to a malfunction. If you’ve ever wondered how to fix a sump pump, you’re not alone; homeowners all over the country find themselves asking this question when they’re facing strange sump-pump-related problems.
Signs Your Sump Pump Needs Repair
Sump pumps rarely go out quietly. They make strange noises or begin operating unpredictably. If you notice any unusual behavior, don’t ignore it; it could be a sign that your sump pump needs attention sooner rather than later.
Strange Noises
When a sump pump is running, it sounds like a soft hum. However, if your sump is making strange sounds, such as grinding, rattling, or thumping sounds, it indicates damaged, worn, or jammed parts.
Pump Running Constantly
A sump pump only activates when the water level rises above the dangerous threshold. If a sump pump is running constantly, it may have a malfunctioning float switch, or it may not be able to handle the water volume.
Sump Pit Filling With Water, But Pump Not Activating
A sump pump’s primary job is to get the water out of the pit. However, if the pit is filling with water and the pump doesn’t activate, it means the pump is not doing its job, either due to a faulty switch or an internal malfunction.
Visible Rust or Debris Buildup
Rust on your sump pump system suggests aging and overuse, which can hinder performance and lead to failure. Debris buildup is another problem that can interfere with your sump pump component, such as an impeller.
Foul Odors
A foul odor indicates excessive humidity and mold growth. If your basement has a musty smell despite a sump pump, it means that the pump is not adequately removing moisture, allowing mold to grow.
Basement Leaks Despite Pump Being Present
Sump pumps are extremely effective for preventing basement leaks. It holds the water in a pit and diverts it away from your basement. However, if a sump pump is present and the basement is still leaking, your system requires either repairs or replacement.
Common Causes of Sump Pump Failure
A sump pump can fail for many different reasons. It could be the power supply, a stuck part somewhere, clogs, or almost any other possible problem.
Power Outages or Electrical Issues
A sump pump runs on electrical power. In the event of a power outage or electrical failure, your sump pump will stop working unless you have a battery-powered or battery-backup sump pump system.
Stuck or Faulty Float Switch
A float switch is a small but crucial component of a sump pump that triggers the pump to activate and pump the water. A faulty or stuck float switch will ultimately lead to sump pump failure.
Clogged Intake or Discharge Line
A sump pump works with discharge lines to move water away from your home. If a discharge line is clogged with debris or mud, it will prevent water from exiting the house.
Frozen Discharge Pipe
Alongside clogs, discharge lines can also freeze up in colder temperatures. This will cause water to back up into the sump pit.
Pump Not Sized Properly For the Home
Sump pumps come in various sizes with different power and capacities. If your home is relatively large, a smaller pump will not be enough to proactively pump and evacuate the water, which can cause problems and failure.
Old Age/Wear and Tear
Old age is one of the leading causes of sump pump failure. A sump pump typically lasts 7 to 10 years, and the older it gets, the more maintenance it requires. That also means that the longer your system has been running, the more likely it is to fail.
Step-by-Step Guide: How to Fix a Sump Pump
Luckily, most sump pump issues can be fixed if you address the signs early on. You’ll want to begin with basic checks, and—if needed—examine the system more thoroughly.
Step 1: Check the Power Source
The first step is to make sure you actually have a functioning power source for your sump pump. An electrical malfunction can falsely indicate a problem with a sump pump, so you’ll want to ensure the sump is powered by an adequate electrical supply or a battery system.
Step 2: Inspect and Clean the Pump
Once the power source is correctly identified, inspect the sump pump for physical damage, visible signs of malfunction, rust, and debris. If there is any debris, clean the pump thoroughly to create an accessible space for repairs.
Step 3: Check the Float Switch
A float switch is a sump pump’s trigger mechanism. It tells the pump when to turn on and off based on the water level. Check if your pump’s float switch is faulty, stuck, or damaged; it should freely move up and down.
Step 4: Test the Discharge Line
Your sump pump may be functioning properly, but a clogged discharge line can push water back, making it seem like the sump pump is not working. Check your discharge lines for debris, mud, and rocks, and test them to make sure they work properly.
Step 5: Prime the Pump (If Necessary)
Priming is an additional step that ensures there are no airlocks that reduce pump efficiency, the pump is not running dry (which can damage the motor), and there are no vapor-filled bubbles (cavitation) that can lead to performance deterioration.
Step 6: Reset or Replace Components
If any problematic or damaged components are identified, such as a switch, motor, or impeller, you can replace them and reset the pump to restore it to its ideal condition. Replacing faulty components is a quick and cost-effective way to get your sump pump running properly.
Step 7: Test the Pump Under Normal Conditions
Once all repair steps are complete, it’s time to test the pump under normal conditions. Ideally, the pump should be able to pump and evacuate the water safely through the discharge lines. If the pit is empty, it means your pump is running properly. If not, the problem might be more complex, and you should schedule a comprehensive professional inspection and replacement.
When to Repair vs. Replace a Sump Pump
In many cases, a sump pump can be effectively repaired, especially if it has minor issues like a faulty switch, a clogged intake, or a buildup of debris. These repairs are usually performed on a relatively new pump because repairing in these situations is quick and cost-effective.
However, if a problem is more complex, such as a dead motor, frequent occurrence of problems, or repairs that keep failing, it probably means that your sump pump is old and past or near its extended lifespan. In this case, replacement is a better option to avoid repetitive repair costs on a dated machine. If you’re not sure which option is right for you, reach out to a professional near you to narrow down your choices.
Preventing Future Sump Pump Problems
In addition to repairs, a few well-measured steps can help you prevent future sump pump problems. Inspections, regular cleaning, and proper backup systems all contribute to better water management in your home.
Schedule Regular Inspections and Maintenance
A sump pump requires maintenance to ensure all parts are working properly. Schedule regular inspections and maintenance checkups to make sure your sump pump is always in ideal condition and won’t fail when under strain.
Install a Battery Backup System for Power Outages
A sump pump runs on electrical power, but one of the most common causes of sump pump failure is an electrical malfunction or power outage. Install a battery backup system for your sump pump so that it keeps running even during power outages.
Keep Sump Pit Clear of Debris
Things like dirt, silt, gravel, sand, and even small household items can often get stuck in the pit. Inspect your sump pit for debris and clean it regularly to prevent damage.
Regularly Test Pump Operation by Adding Water to the Pit
A sump pump only activates when water enters the basement, and that mostly happens during rainfall. However, you shouldn’t wait for a rainy day to test your sump pump. Keep testing it regularly by adding water to the pit and ensuring it works properly.
Ensure Discharge Line Extends Away From Foundation
Discharge lines work in conjunction with your sump pump to evacuate water away from the home. Make sure your discharge lines extend away from the foundation and are clear of trash, rocks, and other debris.
