Found roots in my drain but wasn't able to pull up with auger. Used this and within 3 days drains were cleared, instructions say wait up to 3 weeks. Copper sulfate concentration is 99%.

Root Free Drains
Would RecommendThis product is different from the powder form that's flushed down a pipe; it's already in liquid form and I'm using it as a preventative. I love trees and have a couple close to the drainage line, plus trees my neighbor has planted on their side of the pipe. Hope it works. A complicating factor might be the neighbor on the other side and I share the same pipe to the street.

No More Tree Root Intrusion
Would RecommendA few years ago, I had problems with root intrusion in our septic tank. On two occasions I had to have the septic tank pumped out due to this problem. I was recommended to use this product (Zep Root Kill). I have used one bottle in the spring and another in the fall when tree roots are seeking out water sources. Since using this produce for several years, I have not had any further issues with root intrusion. I highly recommend this product for anyone who is experiencing a similar issue.

Great Product
Would RecommendI have some tree roots that grow into a sewer line as determined by a plumber's camera. Once cleared I use this product alternately with a foaming product a couple of times per year and have not had any more blockages due to tree roots. You need to use this product as preventative measure, as it will not remove blockages once they occur.
