Prevent Watery Disaster: Step-by-Step Instructions on How to Check Your Sump Pump Float Switch

A sump pump is an essential component of any basement or crawl space, working tirelessly to remove excess water and prevent flooding. At the heart of a sump pump system lies the float switch, a crucial device that controls the pump’s operation. Maintaining a properly functioning float switch is paramount to ensuring uninterrupted drainage and protecting your property from water damage. This comprehensive guide will provide you with step-by-step instructions on how to check your sump pump float switch, empowering you to keep your basement or crawl space dry and safe.

Inspecting the Float Switch: A Visual Examination

1. Locate the Sump Pump: Begin by locating your sump pump, typically found in a designated sump basin in the lowest point of your basement or crawl space.

2. Identify the Float Switch: The float switch is usually a cylindrical or spherical device attached to a float arm that rises and falls with the water level.

3. Examine the Float: Visually inspect the float for any cracks, leaks, or damage. A damaged float may not respond accurately to water level changes.

4. Check the Float Arm: Ensure that the float arm is securely attached to the float and moves freely without any obstructions.

Testing the Float Switch: Functional Evaluation

1. Fill the Sump Basin: Pour water into the sump basin until it reaches the level where the float switch activates the pump.

2. Observe the Pump’s Operation: As the water level rises, the float switch should trigger the pump to turn on. Once the water is pumped out, the float switch should deactivate the pump.

3. Repeat the Test: Fill the sump basin again and observe the float switch’s response. It should consistently activate and deactivate the pump at the appropriate water levels.

Troubleshooting Common Float Switch Issues

1. Float Switch Not Activating the Pump:

• Check the pump’s power supply and ensure it is receiving electricity.
• Inspect the float arm for any obstructions or damage.
• Replace the float switch if necessary.

2. Float Switch Activating the Pump Prematurely:

• Adjust the float switch’s position to raise the activation level.
• Ensure that the float is not touching the sump basin walls or other objects.

3. Float Switch Not Deactivating the Pump:

• Check the discharge pipe for any blockages or kinks.
• Inspect the check valve for proper operation.
• Replace the float switch if necessary.

Maintaining Your Float Switch: Preventive Care

1. Regular Inspection: Conduct regular visual inspections of the float switch and float arm to ensure they are in good condition.

2. Clean the Float: Remove any debris or dirt that may accumulate on the float to prevent interference with its movement.

3. Lubricate the Float Arm: Apply a small amount of silicone lubricant to the pivot point of the float arm to ensure smooth operation.

Summary: Ensuring Peace of Mind

By diligently checking and maintaining your sump pump float switch, you can rest assured that your basement or crawl space will remain dry and protected from water damage. A properly functioning float switch guarantees uninterrupted drainage, giving you peace of mind during heavy rainfall or other water accumulation events.
