How to Clean Your Leach Field Tank: The Ultimate Guide to Prevent Septic Backups

Maintaining a properly functioning leach field tank is crucial for the health of your septic system. A clogged or malfunctioning leach field can lead to sewage backup, unpleasant odors, and potential contamination of groundwater. This comprehensive guide will provide you with a step-by-step approach to cleaning your leach field tank effectively and efficiently.

Understanding the Leach Field Tank

The leach field tank, also known as a septic tank, is an underground container that collects and treats wastewater from your home. It consists of two compartments: a settling chamber and a digestion chamber. In the settling chamber, solids settle to the bottom, while liquids flow into the digestion chamber. Here, bacteria break down organic matter, converting it into gases and liquids.

Signs of a Clogged Leach Field Tank

• Slow draining or backed-up drains
• Sewage odors around the leach field area
• Lush vegetation or pooling water near the leach field
• Alarm messages on your septic system monitor

Tools and Materials Required

• Septic tank cleaning pump
• Water hose
• Shovel
• Gloves
• Safety goggles
• Respirator
• Antibacterial soap

Safety Precautions

• Wear gloves, safety goggles, and a respirator to protect yourself from harmful bacteria and gases.
• Keep away from children and pets during the cleaning process.
• Do not smoke or use open flames near the leach field area.

Step-by-Step Cleaning Instructions

1. Locate and Uncover the Leach Field Tank

Using your septic system map or by following the drainage pipes, locate the leach field tank. Remove any soil or debris covering the tank lid.

2. Pump Out the Tank

Connect the septic tank cleaning pump to a water hose and insert it into the tank. Turn on the pump and allow it to extract the liquid and sludge from the tank. Dispose of the waste properly at a designated wastewater treatment facility.

3. Jet and Flush the Tank

Once the tank is emptied, use a high-pressure water jet to clean the walls and bottom of the tank. This will remove any remaining solids or debris. Flush the tank thoroughly with clean water to remove any residual waste.

4. Inspect the Tank

After flushing, inspect the tank for any cracks, leaks, or damage. If any issues are found, contact a licensed septic professional for repairs.

5. Add Septic Tank Treatment

Pour a packet of septic tank treatment into the tank. These treatments contain beneficial bacteria that help break down organic matter and prevent clogs.

6. Refill the Tank

Fill the leach field tank with water until it reaches the outlet pipe. This will help distribute the septic tank treatment and prevent the tank from floating.

7. Replace the Lid and Backfill

Securely replace the tank lid and backfill the excavation with soil. Compress the soil to prevent settling and damage to the tank.

Maintenance Tips

• Have your leach field tank cleaned every 3-5 years, depending on usage and household size.
• Use water-efficient appliances and fixtures to reduce the amount of wastewater entering the system.
• Avoid flushing non-biodegradable items such as wipes, hair, and grease.
• Plant trees and shrubs around the leach field area to prevent soil erosion and provide additional filtration.

Troubleshooting Common Problems

Slow Draining Drains: Check for clogs in your plumbing fixtures or pipes. If the problem persists, you may need to have your leach field inspected.
Sewage Odors: Locate the source of the odor and inspect for leaks or damage to the leach field system.
Lush Vegetation: Excessive growth of plants around the leach field can indicate a clogged system. Trim back plants and inspect the leach field for problems.

When to Call a Professional

If you experience any of the following issues, it is recommended to contact a licensed septic professional:

• Persistent sewage odors or backups
• Signs of leach field failure (pooling water, lush vegetation)
• Cracks or leaks in the leach field tank or pipes
• Complex septic system issues
