Rated 5 out of 5 by a chemical cleaner that really works!!!! About every year or two we would have a backup in our main line and had tried various chemical treatments, but none of them had worked. My brother is a plumber and would have to snake the almost 100 ft. main line which usually took 2 hours each time to free the blockage. He suspected there was a belly in the line somewhere that would accumulate grease, debris, toilet paper, and other things that would normally break down quickly. My wife read about this product and I bought 2 gallons to try. I poured both gallons in at night and in the morning poured about 4 gallons of boiling water followed by hot water. After a couple minutes it backed up again. I waited 10 more minutes and checked, to my amazement the water had receded. Followed by 10 minutes of hot water and the line is clear. Now I don't have to call little brother the plumber except to tell him this product works!!!!!!!! January 4, 2014
Rated 5 out of 5 by It really works I remember the day it happened. A Sunday. The sun was shining, the birds were singing, breakfast was ready, football was about to come on and then things got real dark real fast. The washing machine entered its drain cycle followed quickly by an horrible gurgling, bubbling sound coming from the bathtubs and showers. All kinds pestilence, debris and things I will not even try to describe were flowing in the absolute most opposite way one could imagine. And then nothing. I stood there in shock. I was adding up what it would cost to bring out a plumber on a Sunday to make that soup of death go away. That frightened me even more. I frantically went to work with a plunger. Nothing! It was the mother of all stoppages. I knew there had to be a easy solution. A quick search online for "Main Line Cleaner" led me to this product at Home Depot. I was skeptical. I read the reviews and hoped that everything I read was true. I poured it into the bathroom sink at 2 PM. Hoping I didn't just buy into a bunch of hype. The hours ticked by. Nothing. No movement whatsoever. The pool of disgust just sat there in my tubs mocking me. I decided to retire for the day at 9 PM. It was not going to be a peaceful sleep knowing what was lying in my bathrooms. And then it happened..... It was 9:30 PM. A death groan of the monster that had plagued me all day, followed by a rushing sound of of all that horrible mess going away. I jumped out of bed and prepared a giant pot of boiling water to rinse out all that was left behind. I filled the tubs with hot water and drained them both at the same time to finish the purge. It was done. I won. I couldn't believe it. It really works. Finally something that does what it promises. October 14, 2013
Rated 1 out of 5 by Not for me After reading good amount of positive reviews, I bought two bottles as recommended per instruction in case one is not enough. But no success story for me. Before pouring this into my kitchen sink, at least I had some minimal drain function although it took about 7-8 hours for complete drainage. But it got worse and no water movement for 4 days. I gave up and I ended calling a plumber. Costed me $290, including some parts replacement which were melted due to the chemical reaction from this product. I was hoping to avoid high plumber cost billing with this product but not my case. Wish others good luck. February 26, 2014
Rated 5 out of 5 by Well Worth the MONEY!! I had clogs in the front & master bathroom bathtubs and commodes, when I would used the washer everything would back up into the bathtubs with this ugly gurgling noise. It was a that point I just knew I had an expensive plumbing problem on my hands until I was told about this product by a relative that works for Home Depot. I purchased this product about 5pm immediately went home and poured into the clogged areas. Awoke the next morning and did as instructed...I was able to shower, use washer, toilet flushed without any problems. I will be purchasing another gallon just to keep on hand. Plumber in a bottle!!

Rated 4 out of 5 by Follow Up Follow up to my January 21, 2014 post that it did not work for me. I applied for my refund online, very simple and already got my refund (less than 3 weeks). and got it for both bottles. so it's certainly worth trying. February 10, 2014
