Roebic Laboratories FRK-1LB Roebic FRK Foaming Root Killer, 1-Pound, 1 lb, White

The first time I bought this, I wrote a bad review, as it didn't immediately do anything. But, after a few weeks I noticed my drains were no longer backing up during heavy rainfall. To my surprise the roots had obviously been killed & slowly been washed away. Unfortunately, as roots do, they grew back a couple of years later. Again, same process & same pleasing result. I'm now on my third purchase, which should tell you I'm really pleased with this, as an alternative to digging up the drain & physically removing roots. Which would cost way more!

Great product

Well packaged and in good condition - flushed easily and I hope it works - its a bit early to say. I saw one review where it was no longer powder but this was airtight and triple wrapped in good condition-frothed up nicely and flushed no problem - went to work - no weird chemical odours when I returned. I hope it works because I and unable to access the roots or kill the offending tree. Some granules remained at the bottom of the bowl for a few days afterwards but him used to that with the rock salt I've been using. I'll pop the camera down in a while but I believe it takes a few months for the roots to disappear from the pipe after this treatment.

Great product. Easy to use.

Bought because my neighbour’s tree had got into the shared sewage pipe. I read the reviews and it was highly recommended. So far so good and this spring will show if it needs to be done every two years or longer.

This product did not work at all on my roots. I had to call out a plumber!

Had tree root ingress shown by drain CCTV. Was quoted a thousand quid to remove it! Tried this stuff, and it’s sorted! How do I know? We’ve lived with it in an old house for months. The toilet would block up as loo roll would catch on the tree root and back up. It would never clear itself and would have to jet it with a pressure washer to free it up. Since using this has been a few days of use and it cleared.

Seen reviews on this type of product and they seem to be good but after using it myself it had little to no affect and the roots where still visible after I used it not much foaming really

The powder seemed to have become moist. Didn't foam or clean line after I poured it in.

Ha funcionado correctamente

This has stopped my recurring, yearly sewer rod-out because of the accursed Locust tree the city planted in front of my house. This will be the third year that I have not had to have the guy out to rod tree roots out of my sewer line. I use once a year about the end of June, so far, so good. What I suggest is the same as others, empty the two powders into a small, dry container, mix the two dry powders thoroughly by hand (do not add water!!). Remember, this stuff foams seriously so if you have one of the slower, older "swirly"-flush toilets, start your flush, wait until it is just starting to exhaust and then dump the powder in; if you have a more modern fast-flush, pull the handle and dump the powder at the same instant. You definitely do not want any residue left in the bowl at end of flush. I dump the stuff in just before bed, and let it sit overnight in the line. In the morning just use your bathroom/kitchen normally and the problem will be gone. [UPDATE JUNE 2014]: I have been using this once yearly and still no more problems. As a clincher.... my house is 120 years old and I have no record of the sewer being camera'd, so I hired a service to come in and run a camera through to the connection with the village main line. He completed about an hour ago, and totally clean, no sign of tree roots, collapsed tiles or anything else. Period. I saw it. The man couldn't find anything wrong at all. So, I think this proves that this stuff really works. Nobody will probably read this since is is an aged review, but at least I posted. :) [UPDATE JUNE 2015]: Still no problems, no backup or flooding. Next week I will treat the sewer again, but I think my tree root problems are over. [UPDATE JUNE 2016]: Yup, still good and no problems. [UPDATE MAY 2017]: Oh well, what the heck, I will update as long a I am thinking about it; I don't even think about sewer backup any more :) No problems last summer at all, I am using it a bit early this year, but I think I will be fine. [UPDATE JUNE 2018]: Yup, still root-trouble free. I had no problems last year at all. In addition, my next-door neighbor started using Roebic three years ago and his tree root problems disappeared. I still remind him of my big favor I did telling him about Roebic; very handy when I want to borrow something. :0) Incidentally, Roebic makes a couple of root remover products, be sure that the label specifies FOAMING, not just chemical or crystal powder. I don't know anything about those. My apologies about not answering some who posted a question!! For some reason Gmail stopped notifying me that I had a new post in my review. Guess I should check in occasionally. [UPDATE JUNE 2019]: Here I am again, it's time to do my yearly treatment tonight. No problems last summer/autumn, and my next door neighbor has no problems either since he started using Roebic a few years ago. It sure is a relief not to have to constantly call the sewer guy out. Keep on truckin' folks! [UPDATE MAY 2020]: Yup, still no sewer problems last year. I think this will be my last update, I am not sure if anyone is reading this anymore. Time marches on. This stuff works great for what it is intended. FEB.11/2021: Note that I have tried many times to find the questions directed to me about this product but can't locate them any more. I can edit my posts, but not answer questions, so I'm not ignoring anyone, I just cannot find where the directed questions are. Maybe Amazon doesn't allow this anymore?? I don't know. JUNE 2021: Still no more problems, same with my neighbor. New family moved in 4 years ago, I told them of the sewer problem, and they have no problems either. JUNE 2022: Well, I'm sure folks are getting bored reading this, but what the heck, it's a tradition now :) No problems last year as usual. New family moved in this autumn on the other side of my house, I told them about Roebic and they will use it just for insurance. I don't know what sewer guys are charging now but I'm sure it's a lot more than when I started using Roebic. Keep on truckin' folks! [EDIT] April 2023: Just a thought...I notice some folks post that it didn't work. If you have established root blockage this will not REMOVE it; you must rod-out the main sewer line to get rid of the established roots in it. Then Roebic will prevent new growth from blocking the line. Roebic will not remove established rootage in the line, you must clear it out first. June 2023: Yup. Same as last year, no problems. New family moved in next door, I told them about Roebic and saved them hundreds/thousands of dollars over the next few years of sewer rodding. May 2024: Is this getting boring? No problems last year, but the Cicadas (if you don't know what they are, just web-search it) love that hated Locust tree and are all over it. By the way...occasionally someone asks why there is a small paper in the middle of the bottle; I assume that keeps the two powders separated until you mix them. I don't know why, but it has always been there. Just throw it away. And...sometimes some of the powder is a bit lumpy. No problem, just use a paint stir stick to mix and crush the lumps, takes only 1 minute. May 2025: Yup, here I am again. No sewer problems last year. I will use it tonight as usual. Happy Sewers!!

Great product, good price delivered promptly, very happy.
