Drain Field Clogged? Here’s How to Fix It Yourself and Save Hundreds!

A drain field is an essential component of any septic system, responsible for filtering and dispersing treated wastewater into the soil. However, over time, drain fields can become clogged with organic matter and other debris, leading to a host of problems. If you suspect your drain field is clogged, it’s crucial to take immediate action to clear it and restore your septic system’s functionality.

Identifying Clogged Drain Field Symptoms

Before delving into the clearing process, it’s important to recognize the telltale signs of a clogged drain field:

• Slow Draining: Water takes longer than usual to drain from sinks, showers, and toilets.
• Gurgling Sounds: Air bubbles and gurgling noises may be heard from drains or pipes.
• Sewer Odor: A persistent foul odor may emanate from drains or the yard where the drain field is located.
• Standing Water: Water may accumulate on the surface of the drain field or in low-lying areas.
• Mushy Ground: The ground above the drain field may feel soft or spongy when stepped on.

Clearing Your Drain Field: Step-by-Step Guide

1. Locate Your Drain Field: Determine the location of your drain field by tracing the outflow pipe from your septic tank.

2. Inspect the Drain Field: Walk over the drain field and look for any signs of standing water, mushy ground, or broken pipes.

3. Remove Obstructions: Remove any visible debris, such as leaves, branches, or toys, from the drain field.

4. Aerate the Soil: Use a long-tined aeration tool to puncture holes in the soil of the drain field. This allows oxygen to penetrate the soil and promote microbial activity.

5. Apply Drain Field Cleaner: Pour a commercial drain field cleaner into the septic tank and follow the manufacturer’s instructions. These cleaners contain enzymes that break down organic matter.

6. Flush the System: Run water through all sinks, showers, and toilets to flush the cleaner through the system.

7. Monitor and Repeat: Monitor the drain field for signs of improvement over the next few days. If the problem persists, repeat the cleaning process.

Alternative Clearing Methods

1. Hydrojetting: A high-pressure water jet is used to blast away debris and unclog pipes.

2. Root Removal: If tree roots have invaded the drain field, they may need to be removed professionally.

3. Septic System Additives: Regular use of septic system additives can help prevent clogs by promoting bacterial growth and breaking down organic matter.

Preventing Clogged Drain Fields

1. Proper Septic Tank Maintenance: Regular septic tank pumping and inspections prevent solids from entering the drain field.

2. Avoid Flushing Non-Biodegradables: Items such as paper towels, wipes, and feminine hygiene products should not be flushed down the toilet.

3. Limit Grease and Oil Disposal: Fats and oils can solidify in pipes and block the drain field.

4. Use Water-Efficient Fixtures: Reduce the amount of wastewater entering the septic system by installing low-flow toilets and appliances.

5. Divert Roof Water: Direct downspouts away from the drain field to prevent excess water from overloading the system.

When to Call a Professional

If you’ve tried the above methods without success, it’s time to call a licensed septic system professional. They have specialized equipment and expertise to diagnose and resolve complex drain field issues.

Alternatives to Clearing Drain Fields

In rare cases, it may not be possible to clear a drain field. If the field is severely damaged or the soil is unsuitable for drainage, alternative solutions may be necessary:

• Repairing or Replacing the Drain Field: This involves excavating the old field and installing a new one.
• Installing a Mound System: This is an above-ground system that is used in areas with poor soil drainage.
• Converting to a Sewer System: If a sewer line is available, connecting to it may be the most efficient solution.
