How to Clean and Maintain Septic Tank Outlet Filter

Septic tank maintenance is a crucial aspect of home maintenance that often goes overlooked. One of the most important components of a septic system is the outlet filter, which plays a vital role in preventing solids from entering the drain field. This article will guide you through the process of cleaning and maintaining your septic tank outlet filter, ensuring the longevity and efficiency of your septic system.

Understanding the Importance of Septic Tank Outlet Filters

Before diving into the cleaning process, it’s essential to understand the role of the outlet filter in your septic system. The outlet filter is designed to prevent solids from leaving the tank and clogging the drain field, which can lead to system failure. A well-maintained outlet filter can significantly extend the life of your septic system and save you from costly repairs.

Signs Your Septic Tank Outlet Filter Needs Cleaning

Regular maintenance is key to keeping your septic system running smoothly. However, certain signs indicate that your outlet filter may need immediate attention. These include:

  • Slow draining in sinks and bathtubs
  • Unpleasant odors around the septic tank area
  • Water pooling around the drain field
  • Backups in toilets and drains

If you notice any of these signs, it’s time to inspect and possibly clean your septic tank outlet filter.

How to Clean Your Septic Tank Outlet Filter

Cleaning your septic tank outlet filter is a relatively straightforward process that you can do yourself. Here’s a step-by-step guide:

  • Step 1: Locate the outlet filter. It’s typically located in the septic tank’s outlet tee.
  • Step 2: Remove the filter. Be sure to wear gloves for this process as it can be messy.
  • Step 3: Rinse the filter with a hose. The goal is to remove all the solids from the filter.
  • Step 4: Once the filter is clean, reinsert it into the outlet tee.
  • Step 5: Check the filter regularly and clean it as needed.

While cleaning the filter yourself is possible, it’s recommended to hire a professional septic service for this task, especially if you’re uncomfortable with the process or if the filter is heavily clogged.

Maintaining Your Septic Tank Outlet Filter

Beyond cleaning, regular maintenance of your septic tank outlet filter is crucial for the longevity of your septic system. Here are some tips for maintaining your outlet filter:

  • Regular Inspections: Inspect your outlet filter at least once a year. If your household generates a lot of solids (for example, if you have a garbage disposal), you may need to inspect it more frequently.
  • Professional Cleaning: Consider having a professional septic service clean your outlet filter every 2-3 years. They can also inspect your entire septic system and address any potential issues.
  • Proper Usage: Be mindful of what goes down your drains. Avoid flushing non-biodegradable items and limit the use of harsh chemicals that can disrupt the bacterial balance in your septic tank.

The Impact of Neglecting Septic Tank Outlet Filter Maintenance

Neglecting the maintenance of your septic tank outlet filter can lead to serious problems. A clogged or malfunctioning filter can allow solids to enter the drain field, leading to clogs and system failure. According to the Environmental Protection Agency, the cost of replacing a failed septic system can range from $3,000 to $7,000, or even more in some cases. Regular maintenance, including cleaning and inspecting the outlet filter, can help you avoid these costly repairs.


Maintaining your septic tank outlet filter is a crucial aspect of home maintenance that can save you from costly repairs and ensure the longevity of your septic system. Regular inspections, proper usage, and professional cleaning are key to keeping your outlet filter and septic system in good working order. Remember, a little effort in maintaining your septic system can go a long way in preventing major problems down the line.
