Blocked drains are a common household problem, but when the blockage is caused by soil, it can be particularly challenging. Soil clogs often occur in outdoor drains, where dirt and debris are more likely to enter the drainage system. Although we’d recommend contacting a professional plumber, fortunately, with the right tools and techniques, it is possible to clear the blockage yourself. Here’s a comprehensive guide on how to unblock a drain filled with soil, including how it might get blocked, signs of soil blockage, and when to call a professional.

How a Drain Might Get Blocked with Soil

Drains can get blocked with soil for several reasons:

  • Poor Drainage Design: Inadequate sloping or improper placement can cause soil to accumulate in the drain.
  • Garden Work: Digging, planting, or landscaping activities can introduce a significant amount of soil into outdoor drains.
  • Heavy Rainfall: Intense rain can wash loose soil and debris into the drainage system.
  • Broken Pipes: Cracked or damaged pipes can allow soil to enter the drainage system and cause blockages.

Signs Your Drain is Filled with Soil

Identifying a soil blockage early can save you time and effort. Look for these signs:

  • Slow Drainage: Water drains slowly from sinks, bathtubs, or outdoor areas.
  • Standing Water: Puddles form around the drain, especially after rainfall.
  • Gurgling Sounds: Unusual noises coming from the drain when water is flowing.
  • Bad Odors: Foul smells emanate from the drain due to trapped debris and soil.
  • Visible Debris: Soil and other debris are visible around the drain cover.

Materials Needed to unblock a soil-filled drain:

  • Protective gloves
  • Safety goggles
  • Drain rods or a plumber’s snake
  • High-pressure hose or pressure washer
  • Bucket
  • Screwdriver
  • Plunger
  • Drain cleaning solution (optional)

Step-by-Step Process to unblock a drain filled with soil:

1. Assess the Situation

Before you begin, put on your protective gloves and safety goggles. Determine the extent of the blockage by checking if water is backing up or draining slowly. If the problem is severe, you might need to call a professional plumber.

2. Locate the Blockage

Identify where the blockage is. If you have access to a drainage map of your property, it can be helpful. The blockage could be near the drain cover or further down the pipe. Start by checking the drain cover for any visible soil or debris.

3. Remove the Drain Cover

Using a screwdriver, carefully remove the drain cover. Be cautious as dirt and debris might be accumulated around the edges. Place the cover aside in a safe location.

4. Clear Surface Debris

Use your hands or a bucket to remove any visible soil or debris around the entrance of the drain. This initial step can sometimes significantly improve water flow.

5. Use Drain Rods or a Plumber’s Snake

Insert drain rods or a plumber’s snake into the drain. Push it down gently, rotating as you go. The goal is to break up the soil blockage and push it through the pipe. You may need to add more rods as you progress deeper into the drain.

6. Flush with Water

Once you’ve broken up the blockage, use a high-pressure hose or pressure washer to flush the drain. Direct the water into the drain to wash away any remaining soil. Keep an eye on the water flow; if it starts to back up, there may still be a blockage.

7. Use a Plunger

If the blockage persists, use a plunger to create pressure and dislodge the remaining soil. Place the plunger over the drain opening and pump vigorously. The suction can help to break up and move the soil further along the pipe.

8. Apply a Drain Cleaning Solution

For stubborn blockages, a drain cleaning solution can be useful. Follow the manufacturer’s instructions carefully. Pour the solution into the drain and let it sit for the recommended amount of time. This can help to dissolve any remaining soil and debris.

9. Rinse and Repeat

After using the drain cleaner, flush the drain with plenty of water to clear out any dissolved debris. Repeat the process if necessary until the water flows freely.

10. Prevent Future Blockages

To prevent future soil blockages, consider installing a drain guard to catch debris before it enters the drain. Regular maintenance, such as cleaning the drain cover and inspecting the drainage system, can also help.

When to Contact a Professional to unblock a drain filled with soil

While many blockages can be handled with DIY methods, there are times when it’s best to call a professional:

  • Persistent Blockages: If the drain remains blocked after multiple attempts to clear it.
  • Severe Damage: If you suspect broken or damaged pipes.
  • Recurring Issues: If blockages happen frequently, a professional assessment is necessary.
  • Complex Systems: If your drainage system is particularly complex or difficult to access.

 

Unblocking a drain filled with soil can be a dirty and challenging task, but with patience and the right tools, it is manageable. Always prioritize safety by wearing protective gear and be prepared to call a professional if the blockage is severe or if you’re unable to clear it yourself. Regular maintenance and preventive measures will help keep your drains clear and functioning properly.
