Septic tanks are an essential part of residential plumbing systems, but unfortunately, they can also suffer from damage over time. From clogs to improper maintenance, there are numerous common causes of septic tank damage that can occur.

Blockages

One of the most common culprits behind septic tank damage is blockages. By far, the most frequent cause of a blocked septic tank is a buildup of solids. These solids can range from food waste to toilet paper and other items not designed to be flushed down the drain. In addition to this, roots from nearby trees and shrubs can also be a cause of blockages. Roots are naturally drawn to the nutrients in septic tanks, and they will naturally seek these out over time. A septic tank repair service will find the source of the blockage and fix it as needed.

Improper Maintenance

Poor maintenance can include not cleaning the tanks regularly or failing to inspect them for leaks. An annual inspection by a professional septic tank repair service will help ensure that your system is running properly. In addition to this, be sure to have your septic tank pumped every three to five years, according to The Clever Homeowner. This pumping will help flush out any solids collecting in the tank and prevent clogs from forming. Failing to do this can put your system at risk for unnecessary damage.

Overuse

Septic tanks have a finite capacity, so you’ll have issues when you exceed it. When more water enters the system than intended, it becomes much harder for the tank to process it properly. This can lead to solids accumulating in the tank and eventually causing damage. Monitor your usage and avoid flushing or draining anything that isn’t necessary. Keeping this usage to a minimum will help ensure your septic tank remains in good working order.

Poor Installation

One common installation mistake is the incorrect sizing of the tank. If it’s too small for the size of your home, you may find yourself dealing with damage due to excess water or poor drain flow. Have a professional inspect any new septic tank installation to ensure it meets all local and state regulations.

Septic tank damage can be costly and time-consuming to repair, so keep an eye out for any of the common causes mentioned above. If you think there is a problem with your system, contact our Red Dirt Septic for septic tank repair immediately.

Popular FAQs

How does aerobic septic installation differ from traditional septic systems?2026-05-14T08:56:08-06:00

Aerobic systems introduce oxygen into the treatment process, producing cleaner effluent that can be dispersed through spray irrigation. Conventional systems rely on soil remediation through a lateral line absorption field.

In Central Oklahoma’s dense clay soils, aerobic systems often provide more reliable performance, a smaller required footprint, and more predictable long-term operation.

Red Dirt Septic has the largest staff of DEQ-certified installers in the state, enabling them to design systems that perform properly in any soil condition or application in Oklahoma.

How often should a septic tank be pumped to avoid damage?2026-05-12T10:16:32-06:00

For optimal performance and to prevent solids from clogging the system, most septic tanks should be professionally pumped every three to five years. Regular pumping flushes out accumulated solids before they can migrate to the drain field and cause permanent damage.

How often does an aerobic septic system need professional inspection?2026-05-12T10:03:17-06:00

While the 2-year mandatory warranty covers initial service, most experts recommend regular inspections (typically every 6 months) through a maintenance plan to check the aerator, pump, and chlorine levels.

Is a septic system warranty transferable to a new homeowner?2026-05-12T09:44:25-06:00

Yes. According to Oklahoma DEQ rules, the mandatory 2-year warranty is fully transferable to new homeowners if the property is sold within the warranty period, ensuring the system remains covered by the original installer.

What is a Continuing Maintenance Agreement (CMA) for septic systems?2026-05-12T09:46:07-06:00

A Continuing Maintenance Agreement (CMA) is a service contract where a professional team, like Red Dirt Septic, performs regular inspections and preventative maintenance on your aerobic system. This ensures compliance with state regulations and helps prevent costly system failures.
