Thank you for trusting Septi-Flow

Step-by-Step Instructions

  • 1) Know Your Tank- Maintenance
    For a 1,000 to 1,500+ gal tank, Pour 1-2 gallons of Septi-Flow directly
    into the toilet, and pour another 2-3 gallons directly into the distribution box.
    Septi-Flow can also be injected into irrigated soil (6-12 inches below the surface) of the leech field to help expedite the process.
