How to Fix a Clogged Septic Tank

Septic tanks are an essential part of many homes, especially those located in rural areas without access to municipal sewer systems. However, like any other home system, septic tanks can experience problems, one of the most common being clogs. This article will guide you through the process of fixing a clogged septic tank, providing valuable insights and practical tips.

Understanding Septic Tanks and How They Work

Before diving into the process of fixing a clogged septic tank, it’s important to understand what a septic tank is and how it works. A septic tank is a large, underground container that collects and treats wastewater from your home. It operates by separating solid waste from liquid, allowing the liquid to flow out into a drain field while the solid waste decomposes over time.

However, if the tank is not regularly pumped or if inappropriate items are flushed down the drain, the solid waste can build up and cause a clog. This can lead to unpleasant odors, slow drains, and even sewage backup in your home.

Identifying a Clogged Septic Tank

Before you can fix a clogged septic tank, you need to be sure that the problem is indeed a clog. Here are some common signs of a clogged septic tank:

  • Slow draining sinks and bathtubs
  • Gurgling sounds in your plumbing system
  • Unpleasant odors around your home or yard
  • Pooling water or lush vegetation around the septic tank area
  • Sewage backup in your home

If you notice any of these signs, it’s likely that your septic tank is clogged and needs attention.

Steps to Fix a Clogged Septic Tank

Once you’ve identified that your septic tank is clogged, you can take the following steps to fix it:

1. Call a Professional

While some minor plumbing issues can be fixed with a little DIY know-how, a clogged septic tank is usually not one of them. Septic tank maintenance and repair require specialized knowledge and equipment, so it’s best to call a professional septic service company.

2. Pump the Septic Tank

The first step in fixing a clogged septic tank is usually to pump it out. This involves removing all the solid waste that has built up in the tank, which can help to clear the clog. According to the Environmental Protection Agency, septic tanks should be pumped every three to five years to prevent clogs and other problems.

3. Clear the Drain Field

If pumping the tank doesn’t solve the problem, the clog may be in the drain field. In this case, the septic service company may need to use a high-pressure water jet to clear the lines.

4. Repair or Replace Damaged Parts

In some cases, a clog may be caused by damaged or worn-out parts in the septic system. If this is the case, these parts will need to be repaired or replaced.

Preventing Future Clogs

Once your septic tank is unclogged, you’ll want to take steps to prevent future clogs. Here are some tips:

  • Have your septic tank pumped regularly
  • Avoid flushing inappropriate items down the drain
  • Use water efficiently to avoid overloading the system
  • Keep trees and large plants away from the septic system to prevent root intrusion


Fixing a clogged septic tank is not a simple DIY task and usually requires the help of a professional septic service company. The process typically involves pumping the tank, clearing the drain field, and repairing or replacing damaged parts. However, with regular maintenance and proper use, you can prevent future clogs and keep your septic system running smoothly.
