BLOG Septic System Troubleshooting: Common Issues and How to DIY Solutions Sep 11, 2025

Dealing with septic system issues can be a daunting task for any homeowner. However, understanding common problems and knowing how to address them can save time, stress, and money. Whether it's a gurgling sound in your drains or unpleasant odors in your yard, ABC Septic Service is here to guide you through the basics of septic system troubleshooting. This blog will help you recognize common issues and offer do-it-yourself solutions before calling in the professionals.

Septic systems are designed to be efficient and require minimal maintenance, yet they can develop problems over time. The most frequent issue homeowners encounter is a slow or completely clogged system. This problem often manifests as slow drains, backups in sinks or tubs, or even noticeable wet spots around the leach field. If you notice these signs, the first step is to reduce water usage to prevent overloading the system. You might also consider using a biological septic tank treatment to help break down solid waste.

Strange odors emanating from drains or around your yard can be another sign that your septic system is struggling. These odors are usually caused by septic gases escaping when there's an issue with the ventilation system or a full septic tank. To combat this, ensure that the vents on your roof are not clogged and inspect for any indications of blockages or damage. Regularly pumping your septic tank every three to five years is crucial in preventing tank overflow and maintaining system health, which should eliminate unpleasant smells.

Gurgling sounds in pipes or drains can also indicate a septic system problem, often resulting from blockages or improper drainage. The noise arises when air is forced through water-backed pipes. Begin your DIY troubleshooting by checking for visible clogs in the fixtures, such as hair or debris in sink and shower drains. If the problem continues, the cause might be deeper within the plumbing, which may require professional cleaning using a plumbing snake or hydro jetting.

Surface water appearing above the tank or leach field, especially without recent rainfall, is a red flag indicating that your septic system is overloaded. This issue might arise from excessive water use, heavy rains saturating the ground, or a malfunctioning drain field. Start by reducing the amount of water your household uses and check gutters and downspouts to ensure they divert water away from your septic area. If water pooling persists, it may be time to consult a professional to evaluate the drain field's health.

Tree roots can also pose a significant threat to septic systems by invading pipes or the tank itself, leading to blockages or leaks. To address this issue, inspect the area around your septic components for large trees or shrubs. If roots are suspected, removing the trees or rerouting the roots are the most effective DIY methods, though a professional might be needed for more severe cases.

In summary, maintaining a healthy septic system involves vigilance and awareness of common septic issues. Regular inspections and timely maintenance are key to preventing costly repairs. When in doubt, the experts at ABC Septic Service are just a phone call away, ready to help with professional solutions. By following these tips and observing your system closely, you can ensure a clean and efficient home environment.
