When heavy rains or melting snow cause a rise in groundwater levels, sump pumps are essential for preventing basement flooding.

However, if your sump pump overflows, it can lead to serious water damage and expensive repairs. In this guide on how to stop sump pump from overflowing, we will discuss how to stop your sump pump from overflowing.
Necessary Items
Before we dive into the steps to stop your sump pump from overflowing, it’s important to gather the necessary items:
- A bucket or container
- Rubber gloves and protective eyewear
- A flashlight
- A sump pump check valve (if you don’t already have one)
12 Steps on How to Stop Sump Pump From Overflowing
Step 1: Turn Off the Power
Before attempting to work on your sump pump, make sure to turn off the power. You can do this by unplugging it or turning off the circuit breaker that powers it. Also, be sure to wear rubber gloves and protective eyewear for safety.
Step 2: Locate the Problem
Use your flashlight to inspect the sump pump. You may find debris or a blockage in the pump that is causing it to overflow. Additionally, check if the float switch is stuck in the “on” position, as this can also cause an overflow.

Step 3: Remove Debris
If you find debris or a blockage in the sump pump, remove it with your hands or a tool like pliers. Be careful not to damage any parts of the pump. Soak up any excess water with a towel or use the bucket to collect the water.
Step 4: Check the Discharge Pipe
The discharge pipe is responsible for carrying water away from your home. Make sure it’s clear of any debris or obstructions. If necessary, use a plumber’s snake to remove any clogs. For example, in the previous step, use a towel or bucket to collect any excess water.
Step 5: Adjust the Float Switch
If the float switch is stuck in the “on” position, gently move it to the “off” position. This should stop the sump pump from continuously running and prevent an overflow. As a safety precaution, make sure the power is still turned off before adjusting the float switch.
Step 6: Check the Check Valve
If your sump pump doesn’t have a check valve or if it’s malfunctioning, water can flow back into the pit and cause an overflow. Install or replace a faulty check valve to prevent this from happening. Even if your sump pump has a check valve, it’s important to regularly check and maintain it.
Step 7: Clear the Sump Pit
Make sure the sump pit is clear of any debris or obstructions. This allows water to flow freely into the pump without causing an overflow. While you’re at it, clean the pit to prevent any buildup of bacteria or mold.
Step 8: Check the Pump’s Capacity
If your sump pump is continuously overflowing, it may be too small for the amount of water it needs to handle. Consider upgrading to a larger capacity pump if this is the case. Then, make sure to follow the manufacturer’s instructions for installation and maintenance.
Step 9: Check the Ground Slope
The ground around your house should slope away from your foundation. If it slopes towards your home, water can collect and lead to an overflow in your sump pump. In this case, you may need to regrade or add soil to create proper drainage.
Step 10: Extend the Discharge Pipe

If your sump pump is continuously overflowing, you may need to extend the discharge pipe to ensure water is being carried far enough away from your home. Aim for at least 20 feet away from your foundation.
Step 11: Regular Maintenance and Inspections
Prevention is key when it comes to avoiding sump pump overflows. Make sure to regularly inspect and maintain your sump pump to catch any potential issues before they become a problem. This includes cleaning the pit, checking the discharge pipe and check valve, and testing the float switch.
Step 12: Consider a Backup System
It’s always a good idea to have a backup system for your sump pump in case of power outages or mechanical failures. This could be a battery-powered backup pump or a generator to keep it running during power outages.
Sump pumps play a crucial role in preventing basement flooding, but they can also cause serious damage if they overflow.
By following the steps on how to stop the sump pump from overflowing outlined in this guide and regularly maintaining your sump pump, you can effectively prevent overflows and keep your home safe from water damage. Remember to always prioritize safety when working with your sump pump and seek professional help if needed.

8 Additional Tips for Maintaining Your Sump Pump
Aside from avoiding potential hazards, there are also some additional tips to keep in mind when maintaining your sump pump. These include:
1) Testing the Sump Pump Regularly
In addition to regular maintenance, it’s important to test your sump pump at least once a year. This will ensure that it is functioning properly and identify any potential issues. Also, test the backup sump pump if you have one.
2) Cleaning and Flushing the Pit
Once a year, clean and flush out your sump pump pit to remove any debris or buildup. This will ensure that the system can operate efficiently and prevent clogs. But be sure to turn off the power before performing any maintenance.
3) Checking the Float Switch
The float switch is responsible for turning on and off your sump pump as needed. Make sure to regularly check it and clean any debris that may be blocking its movement. If the float switch is not working properly, your sump pump will not function effectively.

4) Inspecting the Discharge Line
Regularly check the discharge line for any clogs or obstructions. If necessary, use a plumbing snake to clear any blockages and ensure proper water flow away from your home. Some professionals also recommend installing a backflow preventer to keep water from entering the discharge line.
5) Testing the Check Valve
The check valve prevents the backflow of water into your sump pump and pit. Make sure to test it regularly and replace it if necessary. A malfunctioning check valve can cause issues with your sump pump system.
6) Monitoring the Power Source
Check the power source for your sump pump regularly to make sure it is functioning properly. If you have a backup sump pump, also check its power source and make sure it is ready to activate in case of a power outage.
7) Keeping Up with Maintenance Logs
Keep track of all maintenance tasks and any issues or repairs performed on your sump pump. This will help you stay organized and identify any patterns or recurring problems.
