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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000BQWKUQ | | Are batteries included? | No | | Brand | Roebic | | Customer Reviews | 4.4 4.4 out of 5 stars (5,629) | | Date First Available | 6 August 2012 | | Item Dimensions LxWxH | 11.4 x 19.1 x 5.7 Centimeters | | Item Height | 2.25 Inches | | Item Weight | 454 g | | Item Width | 7.5 Inches | | Item model number | K-77-2LB | | Model number | K-77-2LB | | Net Quantity | 946.35 Milliliters | | Product Dimensions | 11.43 x 19.05 x 5.72 cm; 453.59 g | ## Product Details - **Brand:** Roebic - **Contains Liquid Contents:** Yes - **Global Trade Identification Number:** 00033051001771 - **Item Form:** Liquid - **Item Volume:** 32 Fluid Ounces - **Item Weight:** 454 g - **Net Quantity:** 946.35 Milliliters - **UPC:** 033051001771 789474894833 ## Images ![Roebic Laboratories K-77 Root Killer, 32OZ - Image 1](https://m.media-amazon.com/images/I/71bt538fk2L.jpg) ![Roebic Laboratories K-77 Root Killer, 32OZ - Image 2](https://m.media-amazon.com/images/I/81Vj1mia4NL.jpg) ![Roebic Laboratories K-77 Root Killer, 32OZ - Image 3](https://m.media-amazon.com/images/I/81rurmPkGHL.jpg) ![Roebic Laboratories K-77 Root Killer, 32OZ - Image 4](https://m.media-amazon.com/images/I/81Pjeu8XolL.jpg) ![Roebic Laboratories K-77 Root Killer, 32OZ - 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 ### ⭐ Its not doing any effective on roots *by L***B on 8 December 2025* It doesnt work at all ### ⭐⭐⭐⭐⭐ Very Effective & Easy To Use Sewerline Rootkiller! *by D***E on 30 April 2026* Granular, VERY easy to use and pour into toilet.
