Keeping your septic system running smoothly is crucial, and a key part of that is maintaining the septic tank filter. Cleaning this filter is a straightforward process that helps prevent solids from escaping into your drainfield, protecting its lifespan.
Cleaning a septic tank filter involves safely removing it and washing off accumulated solids directly over the tank opening.
Why Cleaning Your Septic Filter is Essential
Septic systems work by separating solids from liquids. The filter, typically located in the outlet baffle or access riser, acts as a final barrier to catch smaller particles that might otherwise flow into the drainfield lines. Over time, these solids build up on the filter, reducing flow and potentially causing sewage to back up into your home or yard. Regular cleaning, often done annually during your septic system inspection, is vital maintenance.
Step-by-Step Guide to Cleaning Your Septic Filter
Based on common practices and the provided reference, here's how you typically clean a septic tank filter:
- Locate and Access the Filter: The filter is usually found within an access riser or manhole cover directly over the tank's outlet baffle. You may need a tool to lift the lid safely.
- Remove the Filter Cartridge: The filter is typically a cylindrical cartridge or assembly that fits inside a housing or vault. You'll need to remove the filter cartridge by lifting it out of the vault.
- Position and Clean: This is the critical step where you clean the filter. While holding the filter over the open port of the septic tank (so the effluent runs back into the tank) lightly spray the cartridge tubes with a hose to remove material sticking to them. Use moderate water pressure; high pressure isn't necessary and could potentially damage the filter media. Ensure all visible solid material is washed off.
- Inspect (Optional but Recommended): Once clean, quickly inspect the filter cartridge for any damage, cracks, or signs of wear.
- Reinstall the Filter: Carefully place the clean filter cartridge back into its housing or vault in the septic tank outlet baffle. Ensure it is properly seated according to the manufacturer's instructions.
- Secure Access: Replace the access riser lid or manhole cover securely.
What to Expect
When you remove the filter, it will be covered in a slimy, dark material, which is normal accumulated solids. Holding it over the tank ensures this material returns to the tank to be treated further rather than falling onto the ground.
Safety Precautions
- Always wear heavy-duty gloves and protective eyewear.
- Avoid skin contact with septic effluent.
- Work in a well-ventilated area.
- Do not lean directly over the open tank for extended periods, as fumes can be hazardous.
- If you are uncomfortable or unsure, it's best to contact a certified septic professional.
How Often Should You Clean It?
The required cleaning frequency varies depending on the size of your tank, the number of people in the household, and water usage habits. Most manufacturers and professionals recommend cleaning the filter at least annually, often at the same time as your septic system inspection or pumping. Some systems with higher usage may require more frequent cleaning.
Different Types of Septic Filters
While the cleaning method described is common for many cartridge-style filters, filter designs can vary.
| Filter Type | Common Material | Appearance | Cleaning Method (Generally) |
|---|---|---|---|
| Cartridge Filters | Plastic, Fabric | Cylindrical, Tube-like | Spraying with hose over tank |
| Media Filters | Gravel, Sand, Fabric | Integrated into system | May require professional backwashing or replacement |
Note: The cleaning method discussed specifically applies to removable cartridge filters.
Regularly cleaning your septic tank filter is a simple yet effective way to protect your drainfield and extend the life of your septic system.
