Roebic K-77 Root Killer is prohibited by state regulations to be used in Septic Tanks in Florida and Massachusetts and is not for sale in Golden City in Bay County, CA or Jefferson County, Colorado.

When the toilet stops, apply the next third of the bottle and flush the toilet again. Then pour the remaining product in the bottle into the toilet and flush it again. Once the product and water are flowing into the line, limit the use of all water in your house for 6 hours to allow the root to absorb the root pesticides. After 6 hours it will go back to normal water use. Applying the K-77 Root Killer must be applied following as printed on the label Safety Warning Caution: Keep out of reach of children. Avoid skin and eyes. Consult your physician immediately. Please follow manufacturer's directions See more Review: It doesnt work at all Review: Granular, VERY easy to use and pour into toilet. Use once or twice a year, spring and fall best times. I had question and pleasantly surprised when I called and got the tech person picked right up and she answered my question right away. Nice local USA company in Connecticut. The product works, follow easy instructions. Once the roots die off they will break away and float out of your sewer line, so takes time. The flow gets better as a bit of time passes AFTER the treatment, but it does work! It just needs 6 or 7 hours of no water use so overnight, or while youre gone at work, so it sits in sewer line doing its killing, then use water again, go back to normal use. That will help clear out the treatment and killed roots and flush it all away. Great product, great company. ## Features - Kills Sewer and Septic Roots: Roebic K-77 Root Killer removes existing roots and stops new growth in sewers and septic tank quickly, preventing clogging of trees and shrubs - (Prevents re-growth) K-77 copper formula chemically kills roots when entering pipes, preventing regrowth and improves drainage and flow - Safe for all plumbing: Root killer is non-corrosive and safe for all types of plumbing Does not harm surrounding trees, ground plants, septic tanks and natural bacteria in septic deposits - Easy to use: Use every 6 to 12 months - REAL RESULTS: Use the K-77 Root Killer to maintain your system and avoid the inconvenience of root clogging such as backups and surface debris - Quickly destroys clogged roots - Safe for all plumbing Won't damage septic tanks - Save money on expensive digging and hanging work - Not for sale in Bay County, Connecticut, MA - Prohibited for use in Florida Septic Tanks ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000BQWKUQ | | Amazon Bestseller | #1,197,470 in Clothing, Shoes & Jewelry ( See Top 100 in Clothing, Shoes & Jewelry ) #141 in Tobacco Pipe Cleaners | | Brand Name | Roebic | | Contains Liquid Contents? | Yes | | Customer Reviews | 4.4 4.4 out of 5 stars (5,750) | | Global Trade Identification Number | 00033051001771 | | Included Components | Roebic - 33051001771 | | Item Form | Liquid | | Item Type Name | Roebic - 33051001771 | | Item Volume | 32 Fluid Ounces | | Item Weight | 454 g | | Manufacturer | Roebic Store | | Material Features | Non-Toxic, Unscented | | Model Number | K-77-2LB | | Number of Items | 1 | | Part Number | K-77-2LB | | Scent | Unscented | | Size | 32 Ounce (Pack of 1) | | Special Features | Keeps your system running smoothly, Removes clogs | | Specific Uses For Product | Toilet | | Surface Recommendation | Septic tank system | | UPC | 033051001771 789474894833 | | Unit Count | 907.1847 Grams | ## Product Details - **Brand:** Roebic - **Item Form:** Liquid - **Item Volume:** 32 Fluid Ounces - **Material Feature:** Non-Toxic, Unscented - **Number of Items:** 1 - **Scent:** Unscented - **Special Feature:** Keeps your system running smoothly, Removes clogs - **Specific Uses For Product:** Toilet - **Surface Recommendation:** Septic tank system - **Unit Count:** 907.1847 Grams ## Images ![Roebic K-77 Granular Root Killer Chemical Septic System Drain and Sewer Line Pipe Clog Remover Root Exterminator Safe for Bathroom Toilet 32 oz - Image 1](https://m.media-amazon.com/images/I/71bt538fk2L.jpg) ![Roebic K-77 Granular Root Killer Chemical Septic System Drain and Sewer Line Pipe Clog Remover Root Exterminator Safe for Bathroom Toilet 32 oz - Image 2](https://m.media-amazon.com/images/I/81Vj1mia4NL.jpg) ![Roebic K-77 Granular Root Killer Chemical Septic System Drain and Sewer Line Pipe Clog Remover Root Exterminator Safe for Bathroom Toilet 32 oz - Image 3](https://m.media-amazon.com/images/I/81rurmPkGHL.jpg) ![Roebic K-77 Granular Root Killer Chemical Septic System Drain and Sewer Line Pipe Clog Remover Root Exterminator Safe for Bathroom Toilet 32 oz - Image 4](https://m.media-amazon.com/images/I/81Pjeu8XolL.jpg) ![Roebic K-77 Granular Root Killer Chemical Septic System Drain and Sewer Line Pipe Clog Remover Root Exterminator Safe for Bathroom Toilet 32 oz - Image 5](https://m.media-amazon.com/images/I/81ieMsavGSL.jpg) ## Questions & Answers **Q: Is this just copper sulfate which can be bought pure for much less?** A: I think Robert has a good idea there.But, I checked on ebay and the Copper Sulfate Pentahydrate 99% was $10/pound, the same price as this product (now $20 for 2 pounds). 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 ### ⭐ Review *by L***B on December 8, 2025* It doesnt work at all ### ⭐⭐⭐⭐⭐ Review *by D***E on April 30, 2026* Granular, VERY easy to use and pour into toilet.
