Troubleshooting Issues with Your Submersible Sump Pump and Solutions to Fix It

Troubleshooting a Submersible Sump Pump That Isn't Working


A submersible sump pump is a crucial component in many basements and crawl spaces, designed to prevent water accumulation by pumping out any excess water that collects in a sump pit. However, like any mechanical device, it can sometimes fail to operate properly. If you find yourself in a situation where your submersible sump pump is not working, there are several potential issues you can investigate to identify and resolve the problem.


1. Check the Power Supply


The first step in troubleshooting is to ensure that the pump is receiving power. This might seem basic, but it is also the most common issue. Check the following


- Power Outlet Ensure the outlet is functioning by testing it with another device, like a lamp or a phone charger. - Circuit Breaker Check your home’s circuit breaker panel for tripped breakers, and reset any that have flipped. - Power Cable Inspect the power cord of the pump for any visible damage or fraying. If the cord is damaged, the pump will need to be replaced.


2. Inspect the Float Switch


The float switch is responsible for activating the pump when the water level rises. If this component is malfunctioning, the pump will not turn on. Here’s how to check it


- Movement Ensure the float moves freely without obstruction. If it is stuck, remove any debris that might be blocking it. - Position Verify that the float is positioned correctly. Sometimes, the float can become misaligned, preventing it from rising to activate the pump. - Testing Manually lift the float (making sure the pump is plugged in) to see if the pump activates. If it does, the float mechanism might be faulty and may require replacement.


3. Examine the Impeller

If the pump is receiving power and the float switch is operational but the pump still isn’t working, the impeller could be clogged or damaged. The impeller is the component that helps move water through the pump.


- Accessing the Impeller Disconnect the pump from the power source and carefully remove it from the sump pit. Open the casing and inspect the impeller for any blockages such as debris, mud, or hair. - Cleaning If you find obstructions, clean them out carefully. If the impeller is damaged, it may need to be replaced.


4. Check for Clogs in the Discharge Line

Even if the pump is running, a blockage in the discharge line can prevent water from being expelled effectively. Follow these steps to address potential clogs


- Visual Inspection Check the entire length of the discharge pipe for visible clogs or kinks. Look inside the pipe with a flashlight if possible. - Clearing Blockages If you identify a blockage, try using a plumber's snake or a high-pressure hose to clear it.


5. Evaluate the Pump's Age and Condition


If your sump pump is several years old, it might simply be reaching the end of its lifespan. Most submersible sump pumps typically last between 5 to 15 years, depending on usage and maintenance. If you’ve performed all of the above checks and nothing seems to solve the problem, it may be time to consider replacing the pump.


Conclusion


A non-functioning submersible sump pump can lead to serious water damage and costly repairs if not addressed promptly. By methodically checking the power supply, float switch, impeller, discharge line, and the pump's overall condition, you can often identify and resolve the issue. Regular maintenance can also help prolong the life of your sump pump, ensuring it remains reliable when you need it most. If you find that the pump requires repairs beyond your expertise, it may be time to call a professional plumber to assess the situation.
