ZEP 2 lb. Root Kill is an effective solution for ridding your sewer pipes, drain and septic field lines of shrub and tree roots. Plant roots can penetrate through small cracks and poorly sealed joints of sewer lines. If not controlled, these small roots will continue to grow larger causing breakage, reduced flow, and eventually flow stoppage. Root Kill's powerful granular formula dissolves these pipe-clogging elements on contact without harming the target tree or bush.

  • Dissolves septic systems clog-causing roots
  • Powerful granular formula dissolves roots without harming shrubs or trees
  • Protects pipes from corrosion
  • Promotes root and fungus control within sewage system
  • Childproof cap

Rated 5.0 out of 5.0 by Zep Root Kill My home does not have one tree on the property but the homes on both sides have huge, beautiful trees that are about 100 years old. Because I am forever hiring plumbers to relieve my sewer lines (3-4 times per year) from the roots, my handyman suggested I try Zep's Root Kill. Root Kill is a miracle worker it clears the lines without killing the trees. I'm going to use it right through the spring growing season. The drains are already running much better. I plan on stock-piling this stuff. Sure beats the price of the plumbers. I would recommend this to anyone that suspects that they may have a tree root problem. January 23, 2014
Rated 5.0 out of 5.0 by good buy I put in pipe opening and let it do its job. had no problem , drain started working fine . December 18, 2014
Rated 5.0 out of 5.0 by This stuff is awesome After having 2 plumbers at my house at the same time, we found that our problem was not even one that they could fix. I received a bill from them for almost $ 300. combined! (The first plumber didn't have large enough equipment and he recommended we call in a 'nationally known' company) Still neither could fix the problem because of an old sewer piper that angled funny under the ground. We found that our recurrent sewer backup problem was tree roots that invaded the sewer line. I was shocked to learn how damaging tree roots can be to a sewer line, but the roots search out water (moisture) and sewer lines definitely have that...so they will poke right through the pipe. Tree roots can travel underground for quite a distance away from the base of the tree. This product works wonders..and is much cheaper than calling out a plumber or two! ..and talk about easy..you just flush it down the toilet! I would recommend to use this product again after a few years (the roots naturally tend to grow back into the pipe) so that you don't have the problem again. You will know if its happening again if you start to notice the drains clogging up for no aparent reason. December 6, 2013
Rated 5.0 out of 5.0 by Annual treatment I leave in a very wooded area where many neighbors require their drain tile and/or sewer pipes to be roted every few years. I"ve been using ZEP root killer for about 4-5 yrs. I utilize it 1/yr in the early spring...just dump some into my drain tile and also some into the basement toilet as per the directions. Haven't had any issue with my drian tile nor had to make any calls to a plumber. January 4, 2014
Rated 5.0 out of 5.0 by This'll Work In the past, I have had the plumber's out at least once a year to rooter my main drain line for blocks from tree roots. I have started using this product on a regular schedule to help eliminate that annual $135 + bill and save myself a little stress from backed up drains till the plumber can get there. I haven't seen that any plants have been hurt from this yet and I will do another review if that changes, but so far this seems a good product. I don't know how it could be easier to use, I just pour it into the cleanout. February 8, 2014
Rated 4.0 out of 5.0 by Works if used correctly. This product is most effective right after the rooter tool has been used to clear the lines of any roots. Those cut roots are now exposed and this product will have better penetration to finish the job. Apply it through the trap or toilet but don't flush it with too much water. It has to sit in the pipe to work. As for that other review: A bubbling toilet? September 12, 2012
Rated 1.0 out of 5.0 by Caution! This can ruin your pipes. This is a obsolete copper sulfate product. Copper sulfate is highly corrosive to iron and steel pipes AND it doesn't affect roots in the top part of the pipe where roots often enter and thrive. I am about to buy a treatment but this time I'm going to use Home Depot's foaming dichlobenil treatment, which DOES kill roots at the top of pipes. Don't take my word for it -- search for "cornell copper sulfate pipes" and you'll see the university research. I qoute: "Copper sulfate is classified as a hazardous substance... highly corrosive to plain steel iron and galvanized pipes." I am ashamed to say I bought this a few years ago and used it without realizing what it was. Perhaps coincidentally I had to replace a pipe this spring that was corroded. June 13, 2014
Rated 5.0 out of 5.0 by Recommended by plumber We had a sewer backup due to tree roots getting into the sewer pipe. We have not had any sewer issues since starting to use this product every few months. I highly recommend it. August 5, 2014
