So it works out the same cost wise. **Q: compare to Roebic FRK-6 Foaming Root Killer, Which one is better? Thanks** A: I really don't know the answer. I've used the other Roebic root killer because we have a long standing problem with roots from a large tree fouling up our plumbing and causing back-ups in the sewage line to the street. I've used it for years and didn't even know about the FRK-6. My off-handed guess would be that the FRK-6 would be great to blast through a tangle of roots with and the K-77 I use is more of a preventive measure. I started using that after I'd spent $$$ having a "roto-rooter" guy ream out the sewer line for the umteenth time. I probably wouldn't hesitate to use the FRK-6 if I had another blockage in my line. I use the K-77 every six months and haven't had to resort to calling a plumber for several years since I started using it. **Q: Has anyone had experience using this product on a slow moving drain WITHOUT having their drain augered?** A: I use that stuff every 3 months 1/3 of a bottle, now I augered my drain because mine had really backed up but I won't stop using this stuff, I haven't had to do anything else with the drain so I imagine it is killing all the roots from growing any further. It's definitely worth a try, I've got a friend within the family that does plumbing and he told me that is about the best on the market! **Q: Is this safe to use in a Septic System without harming the septic mound which is about 200 feet from house?** A: I have used it twice in the past year and to my knowledge there has been no damage to my septic system. The product worked very well. ## Frequently Bought Together - Roebic K-77 Root Killer: Clears Pipes, Stops New Growth, Works for Sewer and Septic Systems - 32 Ounce - Roebic K-570-Q 32-Ounce Leach And Drain Field Opener Concentrate - Environmentally Friendly and Biodegradable Solution - Roebic K-97 Main Line Cleaner: Exclusive Bacteria Digests Paper, Fats, and Grease in Sewer and Septic Systems - 32 Ounces, Liquid --- ## Why Shop on Desertcart? - ๐Ÿ›’ **Trusted by 1.3+ Million Shoppers** โ€” Serving international shoppers since 2016 - ๐ŸŒ **Shop Globally** โ€” Access 737+ million products across 21 categories - ๐Ÿ’ฐ **No Hidden Fees** โ€” All customs, duties, and taxes included in the price - ๐Ÿ”„ **15-Day Free Returns** โ€” Hassle-free returns (30 days for PRO members) - ๐Ÿ”’ **Secure Payments** โ€” Trusted payment options with buyer protection - โญ **TrustPilot Rated 4.5/5** โ€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/5267248-roebic-k-77-granular-tree-root-killer-for-sewer-lines](https://www.desertcart.be/products/5267248-roebic-k-77-granular-tree-root-killer-for-sewer-lines) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-12*
