HOW GRAVITY EFFLUENT FILTERS WORK

Filter Placement: Installed in the outlet pipe of the septic tank, the filter captures solids as wastewater flows out.
Solid Removal: Traps organic and inorganic debris, preventing it from clogging the drain field or causing system backups.
Clarified Effluent: Only filtered wastewater moves to the drain field, reducing strain and extending its lifespan.
Easy Cleaning: Remove the filter periodically (every 6–12 months) for cleaning with a garden hose, ensuring continuous performance.

INSTALLATION AND MAINTENANCE TIPS

Choose the Right Filter: Select a filter based on your tank’s flow rate (e.g., 800–10,000 GPD) and outlet pipe size (typically 4" PVC).
Install Correctly: Place the filter in the septic tank’s outlet tee, ensuring a secure, watertight fit. Use included gaskets or sealant as needed.
Clean Regularly: Check and clean the filter every 6–12 months (or during pump-outs) to remove trapped solids and maintain flow.
Check Local Codes: Ensure compliance with local regulations for effluent filter installation and maintenance.
Professional Help: While DIY-friendly, consider a septic professional for complex systems to ensure proper setup.
