The most effective way to clean drain tiles around your foundation is by using a sewer jetter attached to a pressure washer to flush out accumulated debris.
Here's a breakdown of the process:
Understanding Drain Tile Systems
Drain tiles (also called weeping tiles) are perforated pipes placed around the perimeter of a building's foundation. Their purpose is to collect groundwater and direct it away from the foundation, preventing water damage in basements. Over time, these tiles can become clogged with silt, sand, roots, and other debris, hindering their ability to function correctly.
Cleaning Drain Tiles with a Sewer Jetter
A sewer jetter is a specialized nozzle connected to a high-pressure hose. When attached to a pressure washer, it produces a powerful stream of water designed to break up and flush out clogs in pipes.
Materials You'll Need:
- Pressure Washer: A pressure washer with sufficient PSI (pounds per square inch) is essential. Check the sewer jetter’s specifications for the recommended PSI.
- Sewer Jetter Kit: This includes the jetter nozzle and a long, flexible hose.
- Garden Hose: For supplying water to the pressure washer.
- Work Gloves: To protect your hands.
- Safety Glasses: To protect your eyes from debris.
- Shovel: To expose the drain tile cleanouts.
Steps for Cleaning Drain Tiles:
-
Locate the Drain Tile Cleanouts: These are typically vertical pipes that extend above ground near the corners of your house. You may need to dig slightly to expose them. If you can't find cleanouts, you may need to access the drain tile through the sump pump pit, if you have one. If you don’t have cleanouts and can’t access through a sump pump, consult a professional.
-
Prepare the Sewer Jetter: Connect the sewer jetter nozzle to the pressure washer hose, following the manufacturer’s instructions.
-
Insert the Jetter Hose: Carefully insert the jetter hose into the drain tile cleanout.
-
Turn on the Pressure Washer: Start the pressure washer and begin feeding the jetter hose into the drain tile. The high-pressure water will loosen and flush out debris.
-
Work the Hose Back and Forth: Slowly move the hose back and forth along the length of the drain tile to ensure thorough cleaning.
-
Flush Multiple Times: Repeat the process several times, flushing the drain tile until the water runs clear. This may require moving to different cleanouts to ensure the entire system is clean.
-
Monitor Water Flow: Observe the water flowing out of the drain tile outlets (e.g., into a ditch or storm drain). The flow should increase as the clog is cleared.
-
Reassemble and Test: Once the cleaning is complete, reassemble the cleanouts. Test the drain tile system by pouring water near the foundation to ensure it drains properly.
Alternative Methods and Considerations
- Professional Drain Cleaning: If you are uncomfortable performing this task yourself, or if the clog is severe, consider hiring a professional drain cleaning service. They have specialized equipment and expertise to handle complex drain tile issues.
- Preventative Measures: To prevent future clogs, consider installing gutter guards to minimize debris entering your drainage system and regularly inspect and clean your gutters.
By following these steps, you can effectively clean your drain tiles and maintain a dry and healthy foundation.
