I just have to wait and see if it works. Review: Did not work - We had an influx of Jasmine roots into our pipework and thought that this would kill them off. The Jasmine was cut down last summer and is no longer growing. The K77 Root Killer was put down as per the instructions and left for 12 hours. There was no difference to the obstructive roots and we had to get the professional drain company to come out and use a specialist machine to cut them and then pull them out. All Clear now! Hooray. ## Features - Causes serious eye irritation. - Causes skin irritation. - Harmful if swallowed. - Very toxic to aquatic life with long lasting effects. - KILLS ROOTS IN SEWER AND SEPTIC PIPES: Roebic K-77 Root Killer clears existing roots and stops new growth fast from sewer and septic pipes, keeping lines free from clogging tree and shrub roots - PREVENTS RE-GROWTH: The K-77 copper formula chemically kills roots at the point of entry into pipes to prevent re-growth, improving drainage and flow - SAFE FOR ALL PLUMBING: Root Killer is non-corrosive and safe for all types of plumbing and will not harm surrounding trees, ground cover, or the natural bacteria content in septic tanks and cesspools - EASY TO USE: Use every 6 to 12 months - REAL RESULTS: Use K-77 Root Killer to maintain your system and help avoid the inconveniences that result from root clogs such as back-ups and surface break outs - Destroys clogging roots fast - Safe for all plumbing.

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. ## Customer Reviews ### ⭐⭐⭐⭐ Time will tell *by S***R on 17 August 2025* Not a cheap product but fast delivery. Easy enough to use.
