How to Bypass Float Switch on Sump Pump
Sump pumps are essential for protecting your basement from flooding, but sometimes they can malfunction or fail to turn on when needed. One common issue is the float switch, which is responsible for activating the pump when the water level reaches a certain point. If the float switch is not functioning properly, you might be wondering how to bypass it on your sump pump. In this article, we will guide you through the process of bypassing the float switch on a sump pump, ensuring that your basement remains dry and protected.
Understanding the Float Switch
Before we dive into the bypassing process, it’s important to understand the float switch’s role in your sump pump system. The float switch is a crucial component that operates on a simple principle: when the water level rises, the float attached to the switch moves upwards, triggering the pump to turn on and remove the excess water. Conversely, when the water level drops, the float descends, and the pump turns off.
However, over time, the float switch can become stuck, damaged, or misaligned, leading to its failure to activate the pump as intended. Bypassing the float switch can be a temporary solution to keep your sump pump running until you can replace or repair the switch.
Materials Needed
Before you begin, gather the following materials:
– A screwdriver
– A replacement float switch (if necessary)
– A pair of pliers
– A wire connector (if needed)
Step-by-Step Guide to Bypassing the Float Switch
1. Turn off the power to the sump pump at the circuit breaker to ensure your safety.
2. Unplug the sump pump from the electrical outlet to disconnect it from the power source.
3. Open the sump pump’s housing by removing the screws that hold it in place. Set the housing aside.
4. Locate the float switch within the sump pump. It is usually a lever or rod attached to a float that moves up and down with the water level.
5. Using a screwdriver, disconnect the wires connected to the float switch. If the connections are tight, you may need to use pliers to loosen them.
6. Once the wires are disconnected, take note of their positions or take a picture for reference, as you will need to reconnect them later.
7. Remove the float switch from its mount. If the switch is damaged or stuck, you may need to replace it with a new one.
8. Connect the wires from the float switch to the pump’s motor terminals. If the connections were tight before, you may need to use a wire connector to ensure a secure connection.
9. Reinstall the float switch onto its mount, ensuring that it is properly aligned with the pump’s motor terminals.
10. Reassemble the sump pump’s housing, securing it with the screws.
11. Reconnect the sump pump to the electrical outlet and turn the power back on at the circuit breaker.
12. Test the sump pump by pouring water into the sump pit. The pump should turn on and remove the water as it rises.
Conclusion
Bypassing the float switch on your sump pump can be a temporary solution to keep your basement dry while you address the underlying issue with the switch. However, it’s important to remember that this is only a temporary fix, and you should eventually replace or repair the float switch to ensure the long-term functionality of your sump pump system. If you’re not confident in performing the bypass yourself, it’s always a good idea to consult a professional plumber for assistance.
