Roebic K-77 Granular Root Killer Chemical Septic System Drain and Sewer Line Pipe Clog Remover Root Exterminator Safe for Bathroom Toilet 32 oz

It doesnt work at all

Granular, VERY easy to use and pour into toilet. Use once or twice a year, spring and fall best times. I had question and pleasantly surprised when I called and got the tech person picked right up and she answered my question right away. Nice local USA company in Connecticut. The product works, follow easy instructions. Once the roots die off they will break away and float out of your sewer line, so takes time. The flow gets better as a bit of time passes AFTER the treatment, but it does work! It just needs 6 or 7 hours of no water use so overnight, or while youre gone at work, so it sits in sewer line doing its killing, then use water again, go back to normal use. That will help clear out the treatment and killed roots and flush it all away. Great product, great company.

its good

Not a cheap product but fast delivery. Easy enough to use. I just have to wait and see if it works.

This stuff is AWESOME! This product saved me from incurring 9K+ plumbing bill I was quoted. My washer drain floor pipe had what seemed to be a complete blockage. It's on a concrete slab so roots infiltrated that pipe. I knew it wasn't the main line because everything else in the house was working properly. Also the time that it took to overflow showed the clog was not too far away. The plumber used an auger on the floor pipe and hit roots about 25 feet in. One of his colleagues was going to use imaging to see exactly where the clog began. However, since the p trap was very weirdly placed below the subfloor their plan was to drill.... Right through my flooring, subfloor, and the concrete slab in my laundry area. I told them to let me sleep on it and was placing this order before they pulled off. I only used about half of the bottle, about a fourth of the bottle one night and another fourth 2 days later. On the 2nd application I washed clothes to flush the product down and to my surprise, the clog was completely gone. No issues at all. Under $20 vs. over $9200! I will be sure to always have this on hand.
