DIY Drainfield Repair Techniques

Drainfields, also known as leach fields or septic drain fields, are an essential part of any septic system. They are responsible for removing contaminants from the liquid that emerges from the septic tank. Over time, however, drainfields can become damaged or clogged, leading to a variety of problems. In this article, we will explore some DIY drainfield repair techniques that can help you maintain the health and functionality of your septic system.

Understanding the Problem

Before diving into the repair techniques, it’s crucial to understand the common problems that can affect a drainfield. These include:

  • Overloading: This occurs when too much water is flushed into the septic system, causing the drainfield to become oversaturated.
  • Blockages: These can be caused by solids from the septic tank or roots from nearby trees infiltrating the drainfield pipes.
  • Chemical damage: Certain chemicals can kill the beneficial bacteria in the septic system, disrupting the breakdown of waste and leading to clogs.
  • Physical damage: This can be caused by heavy vehicles or equipment being driven over the drainfield.

DIY Drainfield Repair Techniques

Once you’ve identified the problem, you can proceed with the appropriate repair technique. Here are some DIY methods you can use:

1. Reducing Water Usage

If your drainfield is overloaded, the simplest solution is to reduce your water usage. This can be achieved by:

  • Fixing any leaking faucets or toilets
  • Spreading out laundry loads throughout the week
  • Installing water-efficient appliances

2. Removing Blockages

If your drainfield is blocked, you may need to physically remove the obstruction. This can be done by:

  • Using a drain snake to dislodge the blockage
  • Employing a high-pressure water jet to break up the obstruction
  • Excavating the area and manually removing the blockage (for severe cases)

3. Using Septic System Additives

Septic system additives can be used to restore the balance of bacteria in your septic system. These additives can be poured directly into your septic tank and can help break down waste more effectively.

4. Repairing Physical Damage

If your drainfield has been physically damaged, you may need to repair or replace the affected pipes. This can be a complex task and may require professional assistance.

Preventive Measures

Prevention is always better than cure. Here are some preventive measures you can take to maintain the health of your drainfield:

  • Avoid driving or parking heavy vehicles on your drainfield
  • Plant trees at a safe distance from your drainfield to prevent root infiltration
  • Regularly pump your septic tank to prevent solids from reaching your drainfield
  • Avoid flushing non-biodegradable items down the toilet
  • Limit the use of harsh chemicals that can disrupt the bacterial balance in your septic system

When to Call a Professional

While DIY techniques can be effective for minor drainfield issues, more severe problems may require professional intervention. If you notice persistent foul odors, slow drains, or wastewater surfacing in your yard, it’s time to call a septic system professional.


Drainfield problems can be a major inconvenience, but with the right knowledge and techniques, you can tackle many issues yourself. By understanding the common problems that can affect a drainfield and employing the appropriate DIY repair techniques, you can keep your septic system running smoothly. However, remember that prevention is key, and regular maintenance can help avoid many drainfield issues. Finally, don’t hesitate to call a professional if the problem persists or worsens, as some issues may be beyond the scope of DIY repairs.
