Roebic K-77 Root Killer: Clears Pipes, Stops New Growth, Works for Sewer and ...

This copper root killer works! Back story: I have an acre of land with large trees and lots of plants/vines and the Roebic septic and leech field products have been great in maintaining my septic system for years. I have a basement with a sump hole, a French drain system that runs around the perimeter, and two floor drain holes. Roots grew into the perimeter pipes and the one that leads to the furthest floor drain from the sump hole, causing my basement to flood a few years ago ... right next to the HVAC system and water heater!! After I wasn't able to fix the problem myself, it cost me a few hundred for a plumber to use a large electric auger to cut through and pull out some roots (and he was barely able to do it). A tremendous amount of water flooded into that hole, once he pulled out some roots. This root killer takes time to work, so if you're dealing with a flooded basement and need to higher a plumber first, I highly suggest getting a second sump pump to which you can attach a hose long enough to exhaust the water out of your house; if I hadn't done this, that extra water would have flooded my basement by my sump hole when the roots were cut. After that, I made sure I used root killers as maintenance. I tried a different brand for the next couple years - water kept running through the sump pipes all year long and the water level in the furthest floor drain remained just below floor level. Since this past winter, I noticed the water level in the drain intermittently rising and dropping. In February, poured a bottle of the Roebic foaming non-copper version in my toilet and didn't notice any difference in the floor drain. About a couple weeks later, I poured a bottle of Roebic K-77 (copper version) into my toilet and a few tablespoons into the basement floor drain - still no difference in the water level and water continously ran through the sump pipes. (The plumber had cut only enough roots to let the water rush out and unflood my basement.) With the extra rainfall this spring and summer, I've kept an eye on my floor drain and noticed the water rising above the drain again and some wet areas around the perimeter of my basement towards the backyard. After reading up on the effects of copper on roots, I purchased two more of the Roebic K-77 copper root killer and poured a bottle into my toilet in early June; still no difference the the water level of the floor drain. About a month later, I poured the second K-77 bottle into the toilet, minus a few tablespoons, which I poured directly into the basement drain hole. About 2 weeks later, the water in the floor drain receded. The water in the floor drain has continued to recede; it's been a month since the last bottle and I can't see any water in the drain, the perimeter of my basement is dry again, and no water runs through the sump hole pipes unless it rains or I'm doing laundry. I have a backup sump pump installed, but I've gone to the basement several times to check on the regular pump because it barely runs! The combination of the 2 bottles of K-77 in the toilet and the few tablespoons in the floor drain worked to kill the roots that have been causing water to back up in my basement drain system!

I’ve been using this product for 3 or 4 years. Usually dump in toilet before Vacation , This year i forgot to use it and by mid October my sewer pipe was clogged. When using a sewer machine to open drain i pulled out a large amount of ROOTS!! So i definitely believe in this product and will not forget again!

It is of excellent quality, and I love it.

In 2024, our line backed up due to roots. The plumber came out with his blades and took care of it, but four months later, they were right back. I picked this up and now use it every 3 months. Maybe it's a coincidence, but we haven't had the issue again, and this was through spring and summer. Since the first issue happened in late fall/early winter, we'll see if it improves. For me, $20 a month is better than paying a plumber.

Did I actually need this? Not sure, but I do have mature trees located along one side of my leach field and figured that it was worth the cost to add it to my system. I’m trying to really take care of my 50 year old system because if it fails I’ll be required to install a sand mound system - at a cost of 30 to 40 grand. I’m a senior citizen on disability, and I’d rather spend my limited resources on almost anything other than a new septic system. I trust Roebic products, and have used them for years.

Hasn't done anything in the last month. Still get periodic clogs. But the plunger does clear it out

I guess it worked good. I used it as a precaution.

Great stuff I use to have to hire a plumber every summer because spring brought lots of roots to my pipes by summer nothing drained year after year finally had a plumber tell me about this stuff well 900.oo cheeper then a plumber to cut out the new roots worth a try I was shocked how well this worked. Totally shocked I've been using it for 4 yrs now no need to call the plumber anymore. I start in the spring when they start to grow and put down a cup a week and a couple of cups the beginning of summer I bottle last 2 years so it cost me about 12 bucks a year . If you have roots growing in your pipes give it a try if the roots are already there you have to give it time to kill the roots and detached there selfs and flush on down the pipes the first time it took 3 weeks to get my pipes drained . Got to do it in spring when they first start

It doesnt work at all

its good

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

Doesn't kill the root
