Sump pump not pumping water? expert unveils the startling reasons why

A sump pump is an essential appliance that helps protect your home from flooding by removing excess water from the sump basin. However, if you find your sump pump is dry when it should be working, it can be a cause for concern. This blog post will explore the various reasons why your sump pump may be dry and provide solutions to resolve the issue.

Clogged Discharge Line

One of the most common reasons for a dry sump pump is a clogged discharge line. Over time, debris, dirt, and other particles can accumulate in the discharge line, blocking the flow of water. To check for a clog, disconnect the discharge line from the pump and inspect it for any obstructions. If you find a clog, clear it using a drain snake or a high-pressure water jet.

Faulty Check Valve

A check valve is a one-way valve installed on the discharge line to prevent water from flowing back into the sump basin. If the check valve is faulty or damaged, water can leak back into the basin, causing the pump to run dry. To test the check valve, pour a small amount of water into the discharge line. If the water flows back into the basin, the check valve needs to be replaced.

Float Switch Failure

The float switch is a device that detects the water level in the sump basin and activates the pump when the water reaches a certain level. If the float switch is not working properly, the pump may not turn on when it should. To check the float switch, manually lift it to activate the pump. If the pump does not turn on, the float switch needs to be replaced.

Power Outage

If there is a power outage, your sump pump will not be able to operate. Check your electrical panel to ensure that the circuit breaker for the sump pump is not tripped. If the circuit breaker is tripped, reset it and check if the pump is working.

Frozen Discharge Line

During cold weather, the discharge line can freeze, preventing water from flowing out of the sump basin. To prevent freezing, insulate the discharge line using foam insulation or heat tape. If the discharge line is already frozen, thaw it using a heat gun or a hot water hose.

Pump Failure

In some cases, the sump pump itself may fail due to mechanical issues, electrical problems, or overheating. If you suspect that the pump has failed, unplug it and check for any visible damage. If the pump is damaged, it will need to be replaced.

Incorrect Installation

If the sump pump is not installed correctly, it may not be able to pump water effectively. Ensure that the pump is properly sized for the sump basin and that it is installed at the lowest point in the basin. The discharge line should be properly connected and directed away from the house.

Summary: Troubleshooting Your Dry Sump Pump

If your sump pump is dry, it is important to identify and address the underlying cause promptly. By following the troubleshooting steps outlined in this blog post, you can resolve the issue and ensure that your sump pump is working properly to protect your home from flooding.
