## 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.

## 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.
