It did not work
My kitchen sink is still clogged. Everything else in the house works fine. We tried 25' snake, it did not work. We bought 50' snake - no luck. We found that it is a lateral pipe across the kitchen and living room - no longer then 30' but how the actual pipe runs we don't know. I purchased 2 gallons of Main Line. Read hundred of reviews. Followed instructions. Waited for 9 hours. Miracle did not happen. Such a disappointment.

    Left in the clog over night for a total of 14 hours and it did nothing to unclog the drain. I then talked to two other arbitrary Plummers about this type of drain cleaner and they said most of the time it does not work, unless the clog is mainly only grease related and nothing else.

    Didn't get the job done
    I purchased this item after asking questions via Home Depot live chat and under the product itself. It was highly recommended. However, after using the product as directed our sink was still backing up when the washing machine was dumping. We did have to call a plumber to snake the line where the washing machine drains. That got the job done! Too bad we had to spend $125!!

      I followed directions exactly as stated on the container. I bought 2 gallons because the product was guaranteed or money back. Absolutely zero effect on the main line drain the next morning. I would not buy again because to get your money back you have to email the company describing what happened and then wait 4 weeks for them to send you a check. I went back and bought a bladder for the the drain. Now that worked like a charm.

      I had a near complete main line sewer blockage, and my best bet was that it was from not applying the root killer as often as I should (every six months is advised) and the roots grew back and trapped a lot of undesirable stuff in my main sewer line. I put one whole gallon down, waited eight hours, and then flushed very hot (and boiling water) down the drain. After 2-3 minutes it started overflowing again. It was better, but not by much. I then put another gallon down, waited eight hours and flushed it again with very hot water. This time did the trick and the hot water flush pushed all of the blockage out and into the sewer. It's running at 100% flow now. My advise is to pick up two of these, and if you manage to unblock with one, then take the other one back, but it will be great to have one on hand if you don't succeed with the first attempt, like I did. I'm very encouraged by this product, I would estimate that the $25 dollars I spent saved me $225 in plumber fees to come and snake it in the long run. I'm a very happy customer and bought another gallon to keep in my garage, so I'm prepared next time. But hopefully their wont be a next time, if I keep using the foam root killer, which always did the trick in the past (or replace my faulty sewer main line someday). Bravo Instant Power!

        Worked for my very slow drain
        Our downstairs bathroom clogs up every 7-8 years. I knew it was not the line to the street since the rest of the house was working fine. (We have a huge maple in our front yard and old clay sewer pipes...so we deal with roots once in a while). There was no backup in the utility/sink washer in the basement. This one line is for an addition so the bathroom is the only thing using it. I tried my 6 foot closet auger going through the toilet but no luck. There is a stand up shower in that bathroom so I tried snaking it from there (the water was backing up into there and draining out slowly over a few hours). That is what worked the last time. No luck. I bought a bottle of this and dumped it in at 5pm. 6am the next morning, I ran hot water for the shower and sink for 10 minutes. Also flushed the toilet 5x...all fixed. This stuff works and I am going to buy a bottle of this to have on-hand next time. $10 versus dealing with a disgusting mess trying to snake sewage backup or even worse, $200+ for a plumber. If you do not have safety google or rubber gloves, walk over to that aisle and pick some up. This stuff is hard core and you want to pour it in very slowly and not spash it. The only minor con is time for it to work...you need to leave it in for 8 hours or longer. So if this happens a few hours before you are having people over, you need to snake.

          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!!!!!!!!

                      I have bought this many times before to clean out my basement floor drain when the water from my washer begins to drain slowly. It usually works like a charm, but this time didn't. Could be my drain has a lot of lint in it, but it helped only a little this time, drain is still overflowing on the basement floor but just not as much as it was.

                              It worked to clear a stubborn clog in the main drain pipe from the kitchen and the utility room where the washer dumps into the tub sink. Couldn't clear it with a plunger and not accessible with a snake. So dumped a full two bottles of Mainline in the utility tub/sink and the next morning it was so clear the washer didn't even fill the tub like usual. It flowed faster then ever before.

                                It does work on stubborn kitchen cast-iron drain clogs, but it takes the whole bottle to do it. Doesn't prevent future clogs, as it doesn't seem to clear build-up on cast-iron.
