FOAMING Root Killer | Kills Tree Roots in Pipes & Sewer Lines | Contains No Copper Sulfate | Safe for Pipes and Septic - 4 USES, 10LBS

Worked great now my lines drain better than they have before

works within five days

It's hard to tell if it's doing its job in the sewer pipe — I've scheduled to do this every 3 months, just to be sure it can work properly. I deduct one star because it doesn't foam _that_ much. There is some activity when I pour it into the toilet bowl, but there's not a burst of foaming as I've had with other (more expensive) foaming treatments. In fact, it leaves a sludge at the bottom of the bowl that needs to be flushed several times to clear. Also, I wear a mask while doing this. I noticed before, without a mask, that the fine spray released into the air when pouring in the bowl troubled my breathing. So, use a mask, just to be sure you're not breathing in a chemical that bothers you.

Excellent product. Really works! Just follow the directions. Have been using for maybe about 5 years. Home Depot no longer carry so was happy to learn can order on AMAZON.

I used this to treat some French drains under my patio that run out underneath my yard. Grass roots often clog these up and they are breeding grounds for mosquitos if the water is not moving through them. I figured I would give this a try and see how it does. First off, it's a basic formula of 90% rock salt with the remaining 10% being citric acid (like concentrated lemon juice), sodium lauryl sulfate (soap), and sodium bicarbonate (baking soda). All of these are household ingredients or easily purchased from a grocery store. The foaming is occurring from the reaction between the baking soda and the citric acid when hydrated with water. In other words, you can make a lot of this on your own for a lot less than this product costs. However, it also explains why this formula does not harm trees - there are no enzymes or anything, the high salt concentration will just dehydrate roots and kill them without harming the tree itself. Would it be enough to kill large roots in a pipe? I do not believe it would, but it probably would help as a protective agent to keep smaller roots from growing larger over time (as long as you use the product regularly). As for how well it worked on my drains, the foaming was minimal in the pipes and did not expand enough to fill the entire pipe, so I expect it just cleaned the bottom of the pipe of some dirt/grime buildup. Maybe it will help with mosquitos in there, but I doubt it. IF it works, I will just buy a 50lb bag of rock salt for $10 and mix in some anhydrous citric acid, baking soda, and a little bit of soap. That would be 50 treatments for $20 vs 10 treatments for $30.

This works well but, it does make me cough (and choke) when I'm using it - even when wearing a mask. I can't imagine how bad this would be without one. It does not foam - at least I don't wait around to see if it will. It does the job, but so well, it killed half of my Japanese maple. ( I suspected this was causing the root issue - now I know for sure.) In light of all this, I will continue to use this product. I'm sure it's saved me from a big plumber's bill. Update: This is the second time I've experienced this product delivered where the lid has opened and the product is everywhere. They do nothing to ensure this will not happen. As a result, UPS had to tape the bottom of the delivery box to keep the granules and fine powder from leaking out. Who knows how much was lost before they did that! I had 6 other items in the delivery and all are covered with the powder residue - including a stuffed-animal pet toy that is coated with it as well. (Dogs tend to use their mouths to play with toys - so especially not good.) I had about a cup of the granules in the bottom of the box, not to mention all over my kitchen floor and counter top.

My plumber recommended this to me. Been using for several years now, no more plumbing clogs!

I used Green Gobbler Foaming Root Killer to deal with tree roots in our sewer line, and it worked exactly as promised. The foaming action really helps it reach all areas of the pipe, and I noticed a big improvement in drainage after just one treatment. I also appreciate that it’s copper sulfate-free and safe for both pipes and septic systems. With four uses in one container, it’s a great value. Definitely recommend for anyone dealing with root issues!

Have used just one application, so far seems to have worked well. Easy instructions.

Used this last year, it was the first year I didn't have to have roots cleaned out of my drainage line.

No smell hope it works

Did two treatment as directed and it fixed the problem …cleared whatever roots/ obstructions were impeding the water flow will definitely use this product again

Not sure if it worked. Had my drains cleared due to roots, then bought this. Did a test with it and it didn't foam up. So the question is, does it foam up in the drain? No way to see.
