DIY Septic Tank Outlet Filter Maintenance Tips

Septic tank maintenance is a crucial aspect of home ownership that often goes overlooked. One of the most important components of a septic system is the outlet filter, which prevents solids from entering the drain field. Regular maintenance of this filter is essential to prevent costly repairs and ensure the longevity of your septic system. This article provides a comprehensive guide on how to maintain your septic tank outlet filter yourself.

Understanding the Importance of Septic Tank Outlet Filters

Before diving into the maintenance tips, it’s important to understand the role of the outlet filter in your septic system. The filter is designed to catch and hold larger solids that could potentially clog the drain field. A clogged drain field can lead to system failure, which can be expensive to repair. According to the Environmental Protection Agency, the average cost of repairing a septic system can range from $3,000 to $7,000, or even more if the drain field needs to be replaced.

Recognizing the Signs of a Clogged Outlet Filter

Recognizing the signs of a clogged outlet filter is the first step towards effective maintenance. Some common signs include:

  • Slow draining in sinks and bathtubs
  • Unpleasant odors around the septic tank area
  • Water pooling on the ground above the septic tank
  • Backups in toilets and drains

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

DIY Maintenance Tips for Septic Tank Outlet Filters

Regular maintenance of your septic tank outlet filter can save you from costly repairs. Here are some DIY tips to help you maintain your filter effectively:

1. Regular Inspection

Inspect your septic tank outlet filter at least once a year. If your household generates a lot of waste, consider inspecting it every six months. Regular inspection will help you identify any potential issues before they become major problems.

2. Proper Cleaning

Cleaning the outlet filter is a straightforward process. Simply pull out the filter, hose it down, and replace it. Always wear protective gloves and eyewear when handling the filter, as it can contain harmful bacteria.

3. Avoid Flushing Non-Biodegradable Items

Non-biodegradable items such as diapers, wipes, and feminine hygiene products can clog the outlet filter. Avoid flushing these items down the toilet to prolong the life of your filter and septic system.

4. Use Bacterial Additives

Using bacterial additives can help break down waste in the septic tank and keep the outlet filter clear. However, these should be used as a supplement to regular maintenance, not a replacement.

When to Call a Professional

While DIY maintenance can save you money, there are times when it’s best to call a professional. If you’re uncomfortable handling the filter, or if the filter is still clogged after cleaning, it’s time to call a septic system professional. They have the tools and expertise to handle more complex issues and can ensure your system is functioning properly.


Maintaining your septic tank outlet filter is an essential part of home ownership. Regular inspection and cleaning can prevent costly repairs and ensure the longevity of your septic system. However, it’s important to recognize when professional help is needed. By following these DIY maintenance tips, you can keep your septic system running smoothly and avoid the high costs associated with system failure.
