Sump Pump Float Jammed? Here’s Why and How to Fix It Instantly

Sump pumps are essential devices for homeowners in areas prone to flooding. They help keep basements and crawl spaces dry by pumping out excess water. However, a malfunctioning sump pump can lead to serious water damage. One common issue is a stuck sump pump float. This can prevent the pump from turning on and pumping out water, leading to flooding.

Reasons Why Sump Pump Floats Get Stuck

There are several reasons why a sump pump float may get stuck:

• Debris or Dirt: Debris such as leaves, dirt, or hair can accumulate on the float and prevent it from moving freely.
• Corrosion: Over time, the float can become corroded and stick to the sump pump or the sump basin.
• Misalignment: The float may be misaligned, causing it to get stuck on the side of the sump basin or the pump.
• Damaged Float: The float may be damaged or broken, preventing it from moving up and down properly.
• Frozen Float: In cold climates, the float can freeze and stick to the sump basin.
• Buildup of Minerals: Minerals from hard water can build up on the float, causing it to become heavy and stick.
• Loose Electrical Connections: Loose electrical connections can prevent the float from sending a signal to the pump, causing it to not turn on.

Troubleshooting and Unclogging a Stuck Sump Pump Float

If your sump pump float is stuck, there are several steps you can take to troubleshoot and unclog it:

• Check for Debris: Remove any debris or dirt that may be stuck on the float.
• Inspect the Float: Examine the float for any signs of corrosion or damage. Replace it if necessary.
• Realign the Float: Make sure the float is properly aligned and not rubbing against the sides of the sump basin or the pump.
• Clean the Sump Basin: Remove any sediment or debris that may have accumulated in the sump basin.
• Thaw the Float: If the float is frozen, use a hairdryer or heat gun to thaw it.
• Remove Mineral Buildup: Use a vinegar solution to dissolve mineral buildup on the float.
• Check Electrical Connections: Ensure that all electrical connections are tight and secure.

Why Does My Sump Pump Float Keep Getting Stuck?

If your sump pump float keeps getting stuck, it may indicate an underlying issue:

• Undersized Sump Pump: A sump pump that is too small for your needs may not be able to keep up with the water flow, causing the float to get stuck as it tries to keep up.
• Improperly Installed Sump Pump: A sump pump that is not installed correctly may not be able to pump water effectively, leading to a stuck float.
• Clogged Discharge Line: The discharge line that carries water away from the sump pump may be clogged, causing the float to get stuck as the pump tries to force water through the obstruction.
• Faulty Sump Pump: The sump pump itself may be faulty, causing the float to get stuck or not work properly.

Preventing Sump Pump Float Problems

To prevent sump pump float problems, follow these tips:

• Keep the Sump Basin Clean: Regularly remove debris and sediment from the sump basin to prevent it from clogging the float.
• Inspect the Float Regularly: Check the float for any signs of damage or corrosion and replace it if necessary.
• Install a Float Saver: A float saver is a device that prevents the float from getting stuck on the sump basin or the pump.
• Use a Sump Pump Alarm: A sump pump alarm will alert you if the pump is not working properly, allowing you to address the issue before it causes flooding.
• Consider a Battery Backup Sump Pump: A battery backup sump pump will continue to operate even if there is a power outage, preventing flooding in the event of a stuck float.

Answers to Your Questions

Q: Why does my sump pump float only work sometimes?
A: The float may be sticking due to debris, corrosion, or misalignment. Check for any obstructions and make sure the float is properly aligned.

Q: How do I adjust the float on my sump pump?
A: Locate the adjustment screw on the float arm and turn it to adjust the float’s height. The float should be set so that it turns the pump on when the water level reaches the desired height.

Q: What is a sump pump float saver?
A: A sump pump float saver is a device that prevents the float from getting stuck on the sump basin or the pump. It typically consists of a rod or a tube that the float slides along.

Q: Can I use a sump pump without a float?
A: Using a sump pump without a float is not recommended as it can lead to the pump running continuously or not turning on when needed.

Q: How often should I replace my sump pump float?
A: Replace the sump pump float every 5-7 years or sooner if it shows signs of damage or corrosion.
