Toilet plugged with raw sewage backing up into your bathtub? Try Roebic K-77

Roebic Labratories K-77 – 2 lb Root Killer

Roebic k77


Pros: Works 100% – safe for plumbing – re-growth is prevented

Cons: Highly toxic and dangerous – banned in some states or counties

Finally discovered that I had roots in my sewer line. Ever since buying our home in 2010 our master bath and toilet would always drain slowly however 6 months ago I had a complete blockage. The plumber I hired cleared the line but didn’t say what the cause was or there were roots . A couple months later another backup so I went to Lowes and purchased a hand or drill-driven auger plus a couple of wax rings for the commode. Had to pull the toilet as that’s were we found the location of the original problem.

After a couple minutes, I could hear it flow. When we pulled out the auger there was a small clump of very fine roots at the spiral end, grape vine roots to be exact. I didn’t realize they could travel 7 ft under my slab foundation but they did.

Plan B: Buy root killer

Roebic K-77To kill existing roots then the dead plant growth will seal off the pipe or point of entry preventing re-growth.

Bought this stuff because of all the positive feedback. Only used half the bottle and – poured it onto a paper plate to avoid water splashing into the bottle and ruining the remaining product. Also, poured it in the same time I flushed. Waited 12 hours and noticed how quickly water was draining, especially when I flushed the toilet, like as if the water was being sucked out. Into week 4 and no evidence or problems like before when it would start slowing down after 2 weeks.

Final thoughts:

After reading the manufactures label, consumer reviews and how the product worked, I knew Roebic K-77 would be the cure. It just made perfect sense to poor half the jar (I figured less that 20 ft of line was effected). The foaming chemical would coat the entire pipe, do its duty in 8 to 12 hours then not worry about having to hire a professional to dig up the floor or spend thousands in repairs.

  1. Hi Pat,

    I had the same issue that you appear to be having with your review’s principal image. The solution is quite simple – rather than copy-and-paste the image, save it to your computer. When you post, there is an “Add Media” button just below the main review title above the image box. Click on it and you can then upload the image from your computer’s file and insert it into your review.

    When you’re at the site’s front page, the “How to insert images into your reviews” button is in the upper task bar below the site heading, next to the “Tutorial Videos” button. Andy’s short video on the subject will walk you through the process. It’s really easy, once demonstrated.

    The “FAQs and Tutorials” button in the sidebar of every review will also take you there.

    Great review, Pat! Keep ’em coming!


  2. I noticed that huge picture to the right and it didn’t want to move plus Andy’s got that message in the draft-template section “Insert a huge picture here etc.,”

    Anyway, thanks for the suggestion Rick and it only took about 30 seconds to correct.


  3. “The plumber I hired cleared the line but didn’t say what the cause was or there were roots.”

    Do you suppose he pretty well knew?

    In the mid eighties, at my prior (much older) house, a reasonably experienced personal acquaintance was doing a TOTAL renovation of the bathroom (including even the subflooring), and I only had to hire fully professional help for “plumbing.” When the old toilet was pulled, it became immediately clear why it’d been “flushing slow”: there was a mass of small roots (pretty comparable to what you described). [Moreover, about eight years later I had to pay a large fee to have the entire sewer line (from the back of the house to the street) replaced.] So, I can empathize!

    Glad you found an affordable, trustworthy solution to your plumbing problem.

    1. “Do you suppose he pretty well knew? ”

      I have a feeling he did and figured he’d be back in a month or so. I believe I’ve found the closest thing to a permanent solution and for only 15 bucks. If it happens again I’ll have it inspected with a camera. That’s how we found out why our guest house line was plugged. The previous owner(s) decided not to tie into the main because it was 12 inches below grade. They instead abandoned it. A $99 rod-out and camera inspection special turn into a $4,000 permanent repair.

  4. Thank heavens I’ve never had this problem, but your experience is one I think I’ll remember if the system shows signs of slowing down. EEEUUUWWWW :(

    Great review!
