How Do You Unclog a Sump Pump Discharge Line?

A sump pump is an essential component of any basement waterproofing and drainage system. It helps prevent flooding and water damage by pumping water away from the foundation of your home. However, like any mechanical device, it can also malfunction, particularly if debris clogs the discharge pipe.

In this blog, we'll explore the different parts of a sump pump, how they work together, and what causes clogs in the discharge line. We'll also provide detailed and actionable steps on how to unclog a sump pump discharge pipe.

Parts of a Sump Pump and How They Work

A sump pump consists of several essential components that work together to pump water away from your home's foundation and keep your basement dry. These include the sump pit, the pump itself, the float switch, and the discharge line.

The sump pit is the basin that collects water from the basement. It's usually located in a low point near the foundation walls and is designed to catch any water that seeps into the basement. When the water level in the pit rises to a certain point, the pump activates automatically.

The sump pump is the heart of the sump pump system. It's responsible for removing the water from the sump pit and pumping it out of the basement. The pump runs off a nearby electrical outlet, and it's activated by the float switch.

The float switch is a sensor that turns the sump pump on and off. It's attached to the sump pump and floats on the water in the sump pit. When the water level rises, it lifts the float, activating the pump. When the water level lowers, the float drops, turning off the pump.

Finally, the discharge pipe is the sump pump drain line that carries the water from the pump to a safe drainage area. It's typically made from PVC or corrugated plastic and is buried underground or attached to the side of the house.

What Can Cause Clogs in the Discharge Pipe?

A clogged sump pump drain line is a common problem for homeowners. When the discharge line becomes clogged, the clog will block water from being pumped out of the pit, thus preventing water from flowing freely away from your home. This can cause backups and potentially a flooded basement.

Several factors may contribute to clogs in the discharge line, including:

  • Debris: Dirt, leaves, and other debris can accumulate in the discharge line outdoors and cause blockages. Additionally, debris can build up in the sump pump basin and cause blockages in the drain pipe from the indoors. Over time, this buildup can restrict the flow of water, leading to clogs.

  • Frozen sump pump line: In colder climates, discharge lines may freeze during the winter months, especially if it does not run below the frost line. The frozen water can cause a blockage that prevents the sump pump from functioning correctly.

  • Narrow drain pipe: If the discharge drain pipe is too narrow, it may not be able to handle the volume of water being pumped from the sump basin, causing blockages.

  • Poor installation: Incorrect installation can also lead to clogs in the drain pipe. For example, if the pipe is installed at an incorrect angle or with improper fittings, it may not be able to transport water away from the house.

How to Unclog a Sump Pump Discharge Line

If you notice that your sump pump isn't working properly, it may be due to a clogged discharge line. Here are several actionable steps to perform the sump pump repair and clean out the discharge line:

  1. Turn off the power to the sump pump. Disconnecting the power source is important to avoid any electrical shocks or accidents.

  2. Locate the sump pump discharge line and check for any visible blockages. Remove any debris that you can see.

  3. Snake the discharge line using a plumber's snake. Insert the plumber's snake into the discharge line until you meet resistance and then twist it back and forth until it breaks through the blockage.

  4. Power on the sump pump and observe the water flow out of the discharge line. If the flow is still inadequate, repeat steps 2 and 3 until you have cleared the blockage.

  5. Once you've cleared the clog, flush the drain pipe with clean hot water to ensure that the blockage has been completely removed.

  6. Finally, inspect the pump itself to ensure it's working correctly. Check the float switch and the pump motor to make sure they're functioning correctly.
