DIY Sump Pump Pipe Burial: Step-by-Step Guide for Waterproofing Your Home

Sump pumps are essential for keeping your basement dry by removing excess water and preventing flooding. The discharge pipe is a crucial component of the sump pump system, as it carries water away from the foundation of your home. But can sump pump pipe be buried?

The Answer: Yes, But…

The short answer is yes, you can bury sump pump pipe. However, there are important considerations and regulations to keep in mind before doing so.

When to Bury Sump Pump Pipe

Burying sump pump pipe is typically done when the discharge pipe needs to be extended beyond the reach of the above-ground discharge line. This may be necessary if your home is located on a slope or if you have a long driveway or sidewalk that would obstruct the discharge flow.

Code Requirements

Before burying sump pump pipe, it’s essential to check with your local building codes. Some jurisdictions have specific requirements for the burial depth, materials, and installation methods of sump pump discharge pipes.

Choosing the Right Pipe

Not all pipes are suitable for burying. Choose a pipe that is specifically designed for underground use. This type of pipe is typically made of durable materials such as PVC or ABS, and it has a smooth interior to prevent clogging.

Proper Installation

Proper installation is crucial to ensure the longevity and effectiveness of your buried sump pump pipe. Here are the steps to follow:

1. Excavate the Trench: Dig a trench that is deep enough to bury the pipe at least 12 inches below the frost line in your area. The trench should be wide enough to allow for proper compaction of the soil around the pipe.
2. Install the Pipe: Place the sump pump pipe in the trench, starting from the sump pump discharge point. Use fittings to connect the pipe sections together and ensure a tight seal.
3. Slope the Pipe: The discharge pipe should slope downward away from the house to ensure proper drainage. The minimum slope is typically 1/4 inch per foot of length.
4. Bury the Pipe: Backfill the trench with soil and compact it firmly around the pipe. Avoid using rocks or debris that could damage the pipe.
5. Protect the Discharge Point: Install a discharge elbow or extension at the end of the pipe to direct the water away from your home’s foundation.

Maintenance and Troubleshooting

Buried sump pump pipes require regular maintenance and troubleshooting to ensure they are functioning properly.

• Check for Clogs: The discharge pipe can become clogged over time due to debris or sediment buildup. Regularly inspect the pipe and use a drain snake or hydro jet to clear any obstructions.
• Inspect the Discharge Point: Ensure that the discharge elbow or extension is not obstructed and that water is draining away from the foundation.
• Test the Sump Pump: Test the sump pump regularly to confirm that it is operating correctly and that the discharge pipe is clear.

Alternatives to Burying Sump Pump Pipe

If burying sump pump pipe is not feasible or符合your local codes, there are alternative options available:

• Above-Ground Discharge: The discharge pipe can be routed above ground using a flexible hose or PVC pipe.
• Downspout Extension: Connect the sump pump discharge to an existing downspout to divert the water away from the house.
• Dry Well: Install a dry well in your yard to collect the sump pump discharge and allow it to percolate into the ground.

Wrap-Up

Burying sump pump pipe can be a viable solution when necessary, but it requires careful planning, proper installation, and regular maintenance. By following the guidelines outlined in this guide, you can ensure that your buried sump pump pipe functions effectively and protects your home from water damage.
