Septic systems are the vital components of many homes, especially in rural areas. These systems rely on all parts to adequately function, including the leach and drain fields. The leach field filters and purifies wastewater before it returns to the environment. However, issues can arise that cause the leach field to become clogged, leading to many problems. Understanding the causes of clogged leach fields and exploring effective repair techniques can help maintain the health and longevity of your septic system.

Common Causes of Clogged Leach Fields

Clogged leach fields can result from several factors. Identifying these causes is the first step near effective drain field repair. Some common issues include:

  1. Soil Compaction: Over time, soil in the leach field can become compacted. This compaction reduces the soil’s ability to absorb wastewater, leading to pooling and backups. Heavy machinery or foot traffic over the leach field can contribute to this problem.
  2. Sodium Buildup: Sodium in wastewater can bind with soil particles, creating a complex, impermeable layer known as hardpan soil. This layer prevents water from filtering through the soil, leading to a clogged leach field.
  3. Bio-Mat Accumulation: A bio-mat is a slimy layer formed by anaerobic bacteria waste. This layer can accumulate at the bottom of the trenches in the leach field, just above the hard pan soil layer, blocking the waste water flow.
  4. Organic Overloading: Excessive organic material can overload the septic system, disrupting the bacterial balance and leading to clogging. This can occur from using too many chemical cleaners or not pumping the septic tank regularly.

Preventive Measures for a Healthy Leach Field

Preventing problems in your leach field is easier and more cost-effective than repair. Regular maintenance and mindful practices can help avoid the need for extensive drain field repair. Here are some preventive measures:

  1. Regular Pumping: Pumping your septic tank regularly is crucial to prevent solids from entering the leach field. The pumping frequency depends on the tank’s size and the number of people in the household, but generally, it should be done every 3-5 years.
  2. Mindful Water Usage: Excessive water use can overload the septic system. Spread out laundry loads, fix leaky faucets, and install water-saving fixtures to reduce the burden on your system.
  3. Avoid Chemical Cleaners: Harsh chemicals can kill the favorable bacteria in your septic system, leading to imbalances and clogging. Opt for natural or septic-safe cleaning products.
  4. Protect the Leach Field: Avoid parking vehicles or placing heavy objects over the leach field. Limit foot traffic and plant grass rather than deep-rooted plants, which can interfere with the system.

Effective Techniques for Drain Field Repair

Effective drain field repair techniques are essential when preventive measures aren’t enough and a clogged leach field occurs. RCS II, Inc. offers several solutions to restore your leach field’s functionality.

  1. Septic Drainer: This product is designed to break up and treat clogged soil, restoring drainage in the leach field. Septic Drainer addresses the hardpan soil caused by sodium buildup and improves the absorption capacity of the soil. It’s a cost-effective solution that prevents the need to dig up and replace the soil.
  2. Bio-Septic Boost: This bio-stimulant nutrient enhances the activity level of bacteria in the septic system, helping to consume the bio-mat that contributes to clogging. Made from kelp, it is an all-natural compound that supports a healthy bacterial balance in the system.
  3. Septic Drain Field Repair Kits: These kits include Septic Drainer, Bio-Septic Boost, and easy-to-follow instructions. The kits are tailored to different soil types and levels of failure, ensuring effective restoration of the leach field.

Understanding and Addressing Bio-Mat Formation

Bio-mat formation is a common symptom of drain field failure but not the sole cause. Addressing bio-mat is crucial for restoring proper drainage. Anaerobic bacteria form the bio-mat and can block the wastewater flow in the trenches of the leach field. Here’s how to effectively manage and reduce bio-mat:

  1. Enhance Aerobic Conditions: Introducing aerobic bacteria can help break down the bio-mat. Septic Drainer opens up the soil, improving airflow and creating conditions where aerobic bacteria can thrive.
  2. Add Bio-Septic Boost: This nutrient enhances bacterial activity, promoting the breakdown of the bio-mat. By boosting the natural bacteria in your system, Bio-Septic Boost helps maintain a balanced microbial environment.
  3. Regular Maintenance: Ongoing maintenance with products like Septic Drainer and Bio-Septic Boost can prevent bio-mat from reforming, ensuring the long-term health of your septic system.

Septic System Repair and Maintenance Kits

RCS II, Inc. offers various repair and maintenance kits designed to address specific issues and maintain your septic system’s health. These kits are tailored to different soil types and levels of failure, ensuring effective and targeted treatment.

  1. Drain Field Repair Kit: This kit includes a Septic Drainer and Bio-Septic Boost, ideal for moderately failed leach fields. It breaks up clogged soil and enhances bacterial activity, restoring drainage in the leach field.
  2. Mega Drain Field Repair Kit: This kit is designed for older or immensely failed systems. It includes twice the product of the regular kit, ensuring thorough treatment and faster recovery. The Mega Kit is particularly effective in fine soils impacted by sodium buildup.
  3. Septic Maintenance Starter Kit: This kit is perfect for ongoing maintenance and prevention. It includes a one-year supply of Septic Drainer, Bio-Septic Boost, and a septic tank location marker. Regular use of the kit can prolong the life of your septic system and elude costly repairs.

Long-Term Septic System Care

Investing in long-term care for your septic system can save you money and prevent disruptions. Regular use of maintenance products, along with mindful practices, can keep your system functioning optimally. Here are some tips for long-term care:

  1. Scheduled Treatments: Follow a regular treatment schedule with products like Septic Drainer and Bio-Septic Boost. These treatments prevent buildup and maintain a healthy bacterial balance.
  2. Monitor System Performance: Keep an eye on your system performance. Slow drains, foul odors, or pooling water are signs that your system may need attention.
  3. Professional Inspections: Periodic inspections by a septic professional can catch problems early and prevent more extensive damage. Professionals can provide valuable insights and mention appropriate treatments.

Environmental and Health Benefits

Proper septic system maintenance and repair protect your property and have significant environmental and health benefits. A well-functioning septic system prevents groundwater and surface water contamination, safeguarding drinking water sources and local ecosystems. It also reduces the risk of exposure to unsafe pathogens, protecting your family’s health.


Understanding the causes of clogged leach fields and employing effective repair techniques is crucial for maintaining a healthy septic system. Preventive measures, regular maintenance, and targeted repair products like those offered by RCS II, Inc. can ensure the durability and proficiency of your septic system. By taking captivating proactive steps and investing in quality maintenance, you can avoid costly repairs and enjoy a trouble-free septic system for years.
