Product Description

Product Description

Safe for all types of plumbing, Roebic K-77 Root Killer clears roots from pipes and stops new root growth. The fast-acting copper formula chemically kills roots that find their way into in a home's sewer line, which can cause costly backups. Roots are destroyed at the point of entry into pipes. Once killed, the dead root "seals off" the point of entry and the root cannot re-grow. Non-corrosive, K-77 works without harming surrounding trees, ground cover, or the natural bacteria content in septic tanks and cesspools. Roebic K-77 Root Killer is banned for use in septic systems in the state of Florida and Massachusetts due to state regulations, and is not for sale in Connecticut, the Bay counties of California, and the City of Golden in Jefferson County, CO. For over 50 years, Roebic has developed high quality products engineered for optimum performance, targeting specific problems and troublesome areas within the septic system. Trust Roebic, The Septic Professionals, for all your septic and drain care needs.

Got this after my plumber’s visit to remove roots from my drain
4 Stars
Got this after my plumber’s visit to remove roots from my drain
Roebic Laboratories K-77 Root Killer, 32oz. bottle, contains a crystallized formula and the bottle has an inner seal. The product is easy to use and my plumber recommended that I use it. The active ingredient is 99% copper sulfate pentahydrate.My plumber advised me to use a root killer and I got this one which covers a long length of pipe. I was having problems with a 6 year old toilet making strange noises when flushed. I called the plumber and with a lot of time and machinery, they were able to pull a huge amount of tree roots out of the pipes. I was shocked since I never knew this could be an issue. I am hoping that this product will keep the pipes clear of tree roots in the future.Roebic Laboratories K-77 Root Killer is easy to use and is listed as safe for toilets and pipes. I will continue to use it on a regular basis.
