Unseen Reasons and Common Concerns for Septic Tank Leaks

When it comes to septic tanks, they are known for the inevitable process of releasing wastewater into the ground through absorption holes in their structure. However, leaks are a rare occurrence and understanding the unseen reasons can help homeowners avoid major issues. Severe wetting of the surface should raise immediate red flags, indicating a much bigger problem requiring professional intervention.

Understanding Seepage: Is It Really Leakage?

The confusion often arises when septic tanks are thought to 'leak' the entire contents out through a hole. In reality, the main concern is not the septic tank itself but the dispersion field or a distant location that relies on pumping. A leak from the tank should be inconsequential as solids are unlikely to pass through a crack, and the liquid seeps into the soil naturally. However, in systems where pumping is essential, undetected leaks can be problematic.

The Role of Washing Machine Lint

A common but often overlooked issue is the lint produced by washing machines. These synthetic fibers can clog the tiny absorption pores in the walls of the septic tank, preventing the breakdown of sewage from penetrating the ground properly. Personal experience from my childhood highlights this issue. Our family of seven consistently struggled with a clogged septic tank, which could be visualized and cleaned through the interior walls filled with washing machine lint.

Filter systems, like using old pantyhose, can significantly reduce this problem. More sophisticated filters are available, but the awareness of this issue is crucial for homeowners to prevent clogging and costly repairs.

Identifying and Diagnosing Leaks

Leaking septic tanks are relatively rare, occurring primarily in tanks with leaks in the lower sections or cracks. The inspection of an emptied tank can reveal visible leaks, but smaller ones may not be easily detectable. It’s essential to consider the quality of the tank. Pre-cast concrete tanks are less prone to leaks but require careful installation, while tanks built on-site have more opportunities for leaks due to the multiple joints and seams.

The rate of leakage is also a critical factor. A slow leak might be tolerable in certain scenarios, but a fast leak can quickly become a nuisance and interfere with the proper function of the septic tank. If the fluid level in the tank becomes unsustainable, immediate action including emptying, cleaning, and inspection by a professional is necessary to prevent toxic and asphyxiating gases, making it a job that should be handled by experienced personnel.

Conclusion

Understanding the unseen reasons for septic tank leaks can help homeowners address these issues proactively. By being aware of the common causes such as lint from washing machines and potential leaks, homeowners can maintain their septic systems more effectively. Regular inspections and proper filtration systems are key in preventing severe malfunctions and costly repairs. Remember, safety and health are paramount when dealing with septic systems, making professional intervention the best choice in tackling leaky tanks.
