Was having an issue with my drain and used this . Put it in and let it set for about 7 hours then flushed with hot water and seems to have taken care of the blockage and smell !

I left this on for about 4 hours and once I started pouring hot water i heard sort of like a "lug" sound of water popping / moving and then"¦ no more clog!

admittedly I went overboard and used one whole bottle instead of half. i am re-ordering to keep in my storage in case my sink or anything else gets clogged again!

I used this on my toilet and it seriously unclogged it in ten minutes after it being clogged and slow to drain for days. I was going to let it sit but then I heard whatever blockage make my pipes rumble (they always rumble anyway) and decided to try and flush it and it was back to normal. About half the bottle I pour in and it did the trick

We had a full drain clog. Two plumbers couldn't get it out with augers (likely due to the tough geometry of our drain lines in an older house). When they recommended someone drill into our slab over a long holiday weekend we wanted to give a few options a shot. We tried two other brands with no results.

+For this we used a shop vacuum to fully vacuum out all water from the A/C condensate drain.
+Poured 1/2 bottle
+Let sit overnight 12 hours with no water usage except air conditioner condensate draining in.
+Flushed with 5 minutes scalding hot water
And it worked!!

After having to pay out an obscene sum to a plumber to get me back in the game after my underground sewer lines had been clogged up, I found that I was still floundering, and needed help.
I had been roto-rooted, and now, one year later, in the spring, when the roots are growing again, I was back to square one.
I used the root-killer, and that had helped a lot, but my toilet still wasn't flushing quite right. I knew that there are other things that can cause sewer line backup, but since you can't see underground, you don't know for sure what's going on.
But I definitely did have a clog, so I qualified for this little number.
I poured the entire jug into the toilet, and let it sit overnight. Then, the next morning, when I flushed, (keeping my fingers crossed) it flushed normally, thank God, and acted like a proper toilet should, just as smooth as silk.
It has since been behaving perfectly normally, and I couldn't be more grateful for this fantastic product.
Realistically, all we are trying to accomplish is clear and open sewer lines, so that we can flush away the waste quickly and cleanly, without backups or complications.
However we get to that condition, that's what we should do. If augering out your sewer lines is what needs to be done, that's fine.
But to me, if we can achieve our goal in an easier and less expensive manner, that makes much more sense.
In the past, we didn't have the miracle chemicals that accomplish the job quickly and easily, and a plumber was our only recourse.
Now, however, plumbers are history, as far as I'm concerned.
And it couldn't have happened any too soon.
Quite honestly, just like the aircraft carrier rendered the battleship obsolete, these new natural chemicals have put the plumber on the shelf, where he rightfully belongs, and hopefully, will stay.
They have been shamelessly milking the public for these many years, charging outrageous fees, simply because they have tendered a service that most of us are woefully ignorant about, and helpless in the face of a sewer system that won't drain properly.
But in the end, all we're looking for is normal sewer service, and augering out the sewer line is very temporary, at best, because it only cuts out the tree roots - which will immediately grow back.
But roto-rooting also gives him the opportunity to find untold other "problems," which he will need to "fix," and thereby pad his bill even further.
Plus, getting rid of the hair and gunk that are clogging up the works, and hindering the free flow of the water in the line, which is the other reason for the services of a plumber.
And so, we have two different situations: Roots in the sewer line, as well as hair and gunk clogs, which are two separate problems, needing two different solutions.
But not to worry - Green Gobbler has them both covered, thank goodness!
This is not exactly rocket science, but it is something that most people know virtually nothing about, and has long given the plumber the green light to squeeze us for every nickel he can get.
And believe me, they are not bashful about sticking out their hand, palm up, and expecting you to fill it.
Except it's far from nickel and dime; more like hundreds, or even thousands of dollars.
If the simple introduction into the sewer line of scientifically designed chemicals, which are benign, and will not harm the environment or the skin of the person making the application, but will achieve the desired purpose, my own thought is that this is definitely the way to go.
It goes without saying that a few dollars for a plastic jug of chemicals is considerably easier to deal with than a bill from the plumber that makes you need a second mortgage on your home.
And I am not kidding.
It's definitely a no-brainer, as far as I'm concerned.
