Reveal the truth: easy step-by-step guide to inspecting your sump pump float switch

A sump pump float switch is a critical component of your home’s sump pump system. It detects the water level in the sump pit and triggers the pump to turn on when the water level rises. If the float switch fails, your sump pump may not turn on when it’s needed, which can lead to flooding in your basement.

Signs of a Faulty Float Switch

There are a few signs that may indicate that your sump pump float switch is faulty:

• The sump pump is not turning on when it should. If the water level in the sump pit is high enough to trigger the float switch, but the pump is not turning on, the float switch may be faulty.
• The sump pump is running constantly. If the float switch is stuck in the “on” position, the sump pump will run constantly, even when the water level in the sump pit is low.
• The sump pump is not pumping water. If the sump pump is running but not pumping water, the float switch may be preventing the pump from turning on.

How to Check a Sump Pump Float Switch

If you suspect that your sump pump float switch is faulty, you can check it yourself with a few simple steps:

1. Unplug the sump pump. Before you start working on the float switch, unplug the sump pump to prevent it from turning on accidentally.
2. Remove the float switch from the sump pit. The float switch is typically attached to the sump pump with a few screws. Remove the screws and carefully lift the float switch out of the sump pit.
3. Inspect the float switch. Look for any damage to the float switch, such as cracks or leaks. You should also check the electrical connections to make sure they are secure.
4. Test the float switch. To test the float switch, place it in a bucket of water. The float switch should float on the surface of the water. When you lower the water level, the float switch should drop down and trigger the pump to turn on.
5. Reinstall the float switch. If the float switch is working properly, reinstall it in the sump pit. Make sure to tighten the screws securely.
6. Plug in the sump pump. Once the float switch is reinstalled, plug in the sump pump and test it to make sure it is working properly.

How to Prevent Float Switch Problems

There are a few things you can do to prevent float switch problems:

• Keep the sump pit clean. Debris can build up in the sump pit and interfere with the float switch. Regularly clean the sump pit to remove any debris.
• Check the float switch regularly. Inspect the float switch every few months to make sure it is working properly.
• Replace the float switch every few years. Float switches can wear out over time. Replace the float switch every few years to ensure that it is working properly.

Troubleshooting Common Float Switch Problems

If you are having problems with your sump pump float switch, here are a few troubleshooting tips:

• The float switch is not floating. Check the float switch to make sure it is not damaged. If the float switch is damaged, replace it.
• The float switch is stuck in the “on” position. Clean the float switch and the sump pit to remove any debris that may be preventing the float switch from moving freely.
• The float switch is not triggering the pump to turn on. Check the electrical connections to make sure they are secure. If the electrical connections are secure, replace the float switch.
