How to Troubleshoot and Fix a Sump Pump Float Switch

Your sump pump is an important feature of your home. A sump pump helps get rid of excessive water that comes up through your drains and keeps you from having to deal with a flooded home.

If your sump pump breaks down, you could find yourself in a lot of trouble. You need to know how to fix issues with your sump pump float switch and how to troubleshoot problems when they arise.

In this article, we’ll talk about how you can fix it. Let’s get started!


Defective Float Switch

If the sump pump system isn’t working properly, the most likely cause is a defective float switch. In order to troubleshoot and fix this, the first step is to determine if it is the float switch or the motor that needs to be replaced.

To do this, disconnect the power, remove the float switch, and test it with a multimeter for continuity. If there is no continuity, the switch is defective and needs to be replaced. Once the float switch is replaced, reconnect the power, lower the float switch into the sump pit, and test the operation of the sump pump for proper operation.

Malfunctioning Check Valve

To troubleshoot and fix a sump pump float switch in the event of a malfunctioning check valve, the first step is to make sure the pump is receiving power. This can be done using a multimeter.

If power is present, inspect the check valve for any debris, blockage, or damage. If damage is found, replace the valve. If plumbing issues persist, the valve may need to be replaced. Consult plumbing services for further assistance.

Blocked Discharged Pipe

If your sump pump is not functioning properly, a blocked discharge pipe may be to blame. To troubleshoot and fix the sump pump float switch, first, check to see if the float switch is obstructed by debris or otherwise in the incorrect position. Next, ensure that the discharge pipe is free from any blockage that could interfere with the sump pump’s functioning.

Undersized Sump Pump

In order to troubleshoot and fix an undersized sump pump float switch, the first step is to verify the sump pump is working correctly. To do this, disconnect the float switch from the power source and ensure it is receiving the proper water level. If the water is too low, the switch will not engage correctly.

Often the float arm or cord can be adjusted to add length and lift the float into the correct position. If the water level is too high, the reverse-float option should be checked. If the sump pump is operating correctly, the next step is to check the float switch and wiring for obstructions or disfigurements.
