A small investment in our septic treatment products products can save you years and thousands of dollars in headaches down the road! Our septic system and leach field treatment works great for maintenance and the beginning stages of slowing and deadpan drain fields. Please note: This treatment will not work if your system is completely stopped! When Restoring a Very Soggy and Slow Failed Drain Field or Leach Field System: Easy-to-Use Directions: For Slow or Sluggish Drain Fields/Septic Tanks: Start with 4 gallons of product. we recommend pumping tank first to get the highest possible concentration of the product into the septic drainfield for treatment. Pour 2 gallons of product via the toilet, sink, drain, d-box, or tank opening then flush with water behind it. ▶ Next, additionally if the soil is visibly holding water on the surface use another 4 gallons of product as a surface treatment as follows. Use a very long 12+" screwdriver and poke holes about 6-10 inches down about 1 foot apart into the soil above the drain field. Apply a minimum of 2-4 gallons of product to the holes you have made. ▶For waterlogged systems;Dramatically reduce household water consumption. Try to drain off or septic pump out as much excess water as possible before treatment to increase concentration of product attacking the problem. If you cannot access the distribution or "D-Box," adding additional product via the toilet or sink may be necessary. SEPTI-FLOW SHOCK DIRECTIONS: An average 1,500 gallon septic tank (a 4/3 bed/bath house) start with 4 gallons of product. We recommend pumping the tank prior to treatment. Pour 2 gallons of Septi-Flow Shock into the toilet, tank, distribution box. After 1 week, add 2 more gallons of Septi-Flow Shock. Flush freely with water. Within 2-4 weeks you should see an improvement with the flow. If the septic is completely stopped this product WILL NOT work to address the issue.

It will not work if the soil is completely locked up! Septi Flow will not kill the microbes in your septic tank. **Q: How do I know how much Septi-Flow Shock to use?** A: The recommended amount depends on tank size. For most 1,000-1,500+ gallon tanks, add (One) four-gallon pack of Septi-Flow Shock. For slow/clogged systems due to sodium buildup it is best to pump first. For routine maintenance, pumping is not needed. **Q: How long after treatment will I see results?** A: We always recommend pumping your system (unless you are adding the product for maintenance purposes) before adding this product for the best result. Average results occur in 3-6 weeks, but we have seen improvements in 7-10 days. **Q: How do I know this product is what my system needs?** A: To know if Septi-Flow is right for your septic system the best step is having a septic professional assess it on-site. Even if you use Septi-Flow, we recommend pumping the tank first before treatment; unless you're adding it for routine maintenance. ## Frequently Bought Together - Septi-Flow Shock Septic Drainfield Repair Solution, Clears Leach Fields, Dissolves Hardened Deadpan Soil, Complete Treatment, One Gallon - 128 Fl Oz (Pack of 1) - Drain Field Treatment by Septi-Flow - Roebic K-570-Q 32-Ounce Leach And Drain Field Opener Concentrate - Environmentally Friendly and Biodegradable Solution - Septic Tank Treatment | Septic Enzyme Pods | 1 Year Supply | 2+ Billions CFUs per Pod | Fast-Dissolving, Live Bacteria-Plus Enzymes | Prevents Backups & Odors | Made in USA by Septi-Flow | 12 Packets --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/358192064-septi-flow-shock-drain-field-cleaner-and-leach-field-treatment](https://www.desertcart.co.za/products/358192064-septi-flow-shock-drain-field-cleaner-and-leach-field-treatment) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-11-10*
