Don’t Get Flooded: Learn How to Bypass the Float Switch on Your Sump Pump

If you have a sump pump, you know how crucial it is to maintain the dryness of your crawl space or basement. A vital part of the sump pump, the float switch turns the pump on when the water level in the sump pit rises. To keep the sump pump running properly, you might occasionally need to bypass the float switch. In this post, we’ll walk you through each step of how to bypass the float switch on a sump pump.

Reasons for Bypassing the Float Switch on the Sump Pump

You might need to bypass the float switch on your sump pump for a few different reasons. Below are some of the most typical:

Clogging of float switch: The float switch may become blocked with dirt and cease to function properly, making it impossible for the sump pump to turn on and off.

Faulty float switch: The float switch may stop working properly owing to corrosion, electrical issues, or general wear and tear.

Sump pump short cycling: If the float switch is not set properly, it may cause the pump to turn on and off frequently, resulting in early wear and tear.

Limited space in the sump pit: The float switch may occasionally occupy too much space in the sump pit, making installation and maintenance challenging.

Considerations to Take Before Bypassing the Float Switch

It is critical to take necessary safety precautions before bypassing the float switch on your sump pump. To begin, disconnect the sump pump by unplugging it or turning off the circuit breaker. Second, wear suitable safety equipment, such as rubber gloves and boots, to protect yourself from electrical shock and standing water. Finally, if the sump pump has an alarm, turn it off to avoid it raising an alarm throughout the procedure.

Steps to Bypass the Sump Pump Float Switch

Before beginning the bypass operation, ensure that the electricity to the sump pump is turned off to prevent electrocution. Below are the steps to bypass a sump pump’s float switch:

Step-1. Locate and disconnect the float switch from the sump pump: Typically, the float switch is connected to the sump pump by a piggyback plug or direct wiring. Unplug the piggyback plug from the sump pump if it is present. If the connection is direct, unhook the wires from the sump pump.

Step-2. Identify the kind and wiring of the sump pump: Sump pumps come in two varieties: vertical float switch and tether float switch. Depending on the model of the sump pump, the wiring may vary. Check the instructions provided by the manufacturer to identify suitable wiring for your sump pump.

Step-3. Follow the correct wiring diagram for the sump pump: Once you’ve identified the suitable wiring schematic for your sump pump, be sure to adhere to it precisely. This may involve connecting wires directly to the sump pump or simulating the function of the float switch with a bypass switch.

Step-4. After removing the float switch, test the sump pump. Once the bypass procedure has been finished, power up the sump pump and ensure that it is functioning properly. It is essential to monitor the sump pump for a few days following the bypass to confirm that it is operating properly.

Alternative Methods for Bypassing the Float Switch

There are other ways to get around the float switch if you don’t feel comfortable cutting and splicing wires or if you want a more long-lasting fix. Installing a manual switch that enables you to manually turn the pump on and off is one solution. This may be better left to an expert since it calls for more sophisticated electrical expertise.

Using a backup battery system is an additional choice that will enable the sump pump to function even in the event of a power loss. Although it is more expensive, this option may be advantageous for people who live in locations that have frequent power outages or who want additional peace of mind.


Understanding how to bypass the float switch on your sump pump can be quite useful in an emergency. While it is usually advisable to leave electrical work to professionals, understanding the process is crucial in case of an emergency. Always take precautions and test the sump pump after bypassing the float switch to ensure it is operating properly.

To summarize, bypassing the float switch on a sump pump is a straightforward technique that can be performed in an emergency. You can quickly and successfully bypass the float switch and safeguard your house from water damage by following the necessary safety procedures and understanding the methods involved.
