K-77 Granular Tree Root Killer for Sewer Lines, 32 oz

This has worked great for maintenance! I generally have to have my sewer line snaked once a year. I purchased this product in early April and applied according to directions into the toilet. So far this year, I have not needed a professional service and it has kept the roots from clogging my sewer line. I plan to use it again late October to ,early November before the temperatures drop

20+ years and no issues. I am a believer in root killer dumped annually into the septic system. I had this house built 20+ years ago and even though we have several trees, we have not had a root issue with our septic field. Now, as I’ve mentioned, I do treat the septic system once a year. Not always with the same manufacturer of chemical - personally, I think it’s good to read product testing and see which is the top brand recommendation. Having no issues, tells me I’m doing the right thing. I do recommend premixing the the chemical with water in a 5-gallon bucket, using 1/3 of the contents into 3-gallons or so of water. (Please wear safety goggles and gloves) I stir until the crystals are dissolved then you can either dump the contents directly into the septic tank / drop box / or simply flush down the toilet. I prefer dumping directly into the tank. Do this until the full contents of the container of the container have been mixed and dumped / flushed into the system. Follow up with several flushes or as I do, use a garden hose to flow the contents / root destroyer into the drain field.

Finally found that I had roots in my sewer line. Since buying our home in 2010 our master bath and toilet would always drain slowly however the last 6 months I've hired plumber that cleared the blockage but didn't mention what cause was. Usually there's evidence left on the cutting tip. A couple months later another backup so I went to Lowes and purchased a hand or drill drive auger plus a couple of wax rings for reattaching the commode. Felt an obstruction about 10 ft in then after a minute with the auger I could hear it flow. When we pulled out the auger there were very fine roots at the spiral tip, grape vine roots to be exact. I didn't realize they could travel 7 ft under my slab foundation but they did. Now that the line is cleared I need something to stop the growth. Plan B: Buy root killer Bought this stuff because of all the positive feedback. Only used half the bottle - 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 after the first flush noticed how quickly water was draining, including the bath tub, as if the water was being sucked out. Into week 4 and no evidence or problems like before, when water would start draining slower, after only 2 weeks. ****UPDATE JULY 10, 2014**** Month 3, water backing up in tub, toilet making gurgling noises, ordering another bottle then once the line is clear and dry I'm having the line camera inspected. Will report back later... ****UPDATE JULY 19, 2014**** Minus one star.... Poured in the entire second bottle, waited overnight and no change, as in water backing up in the tub while showering, toilet gurgling. Will try another product this week. I'll try the "foaming" one. Will update later. ***Final Update November 2014 - No roots however*** I did have another clog but it was from natural causes. After I ran the auger to clear the line I called a plumber to perform a camera inspection. Turns out all we have is a tight turn after the "sanitary tee" which then heads towards the laundry room then out towards the main. Someone's been flushing way too much TP plus having "highly efficient - 1.6 gal toilets" in a house built in the 50's does not help with the flow. We almost have to treat the system as if we had septic - which is what the house was originally designed for. Bottom line here would be if you have a reoccurring problem have a camera inspection performed. It tells you everything, including what steps are needed to either prevent or fix the problem permanently. K-77 did remove and has prevented root growth but it is not a permanent solution.

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!

Folks😊 this product is really GOOD... I had roots growing in my pipes 45 to 50 ft out... I had a plumber come and snake my toilet / main line and he explained to me how far it was out... And after he left he told me to get the foaming product to put in my toilet a couple times a year... Well I did that and I noticed that my toilet started going down slower and slower over time... anyway I wind up purchasing 2 Roebic foaming cleaners following directions perfectly and waiting approximately a month to 2 months in between applying.. well it DIDN'T seem to HELP ☹️.. and in all honesty I believe the reason WHY is because the roots was growing TOO FAR out and the foaming product in my opinion probably couldn't reach it?.. I don't know that for sure🤔 but that seems to be a logical reason... I believe the foaming product is good for roots that are growing closer in your main line... I did give a review for ROEBIC foaming drain cleaner here on Amazon... Anyway so what I did is I purchased the ORIGINAL K-77 root drain cleaner and again followed directions perfectly with putting down a third of the container into the toilet and flushing BUT because my flush is weak I also threw a bucket of water to HELP PUSH it through .. anyway I let it sit 10 to 12 hours.. I did it right before I went to bed... With that I woke up and flush my toilet and I thought that I had NEW PIPES or a NEW toilet installed😊.... I haven't had a powerful flush like this in at least 8 to 10 years....THE ORIGINAL ROEBIC K-77 is the BEST... And without a doubt within a few months I'll put another treatment and then another treatment and of course buy more of the K-77... Folks again it was The GOOD OLD standbys and the ORIGINAL that FIXED it 😉.. THANKS for reading..... ALSO NOTE: you do have to have some WATER FLOW and the toilet being able to Flush somewhat...your toilet CAN'T be completely clogged....you have to be able to at least be able to PUSH the K-77 product to the Roots with water...this will NOT work if it's not ROOTS clogging the toilet..

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.

Didn't see a change

Been using this once a year to help keep a main drain line clean and it seems to be working. Much better than the alternative of replacing the main line.

Doesn't kill the root

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

It doesnt work at all

We had an influx of Jasmine roots into our pipework and thought that this would kill them off. The Jasmine was cut down last summer and is no longer growing. The K77 Root Killer was put down as per the instructions and left for 12 hours. There was no difference to the obstructive roots and we had to get the professional drain company to come out and use a specialist machine to cut them and then pull them out. All Clear now! Hooray.

I Would have given 5 but not had chance to work in drain,quick delivery though
