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 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 couldn't believe it. It really works. Finally something that does what it promises.
Pros: Easy to Use

Review 3 for 128 oz. Main Line Cleaner
from Chicago IL
Not for me
PostedFebruary 26, 2014
No, I do not recommend this product.
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.
This was the easiest and best product we have used to clear these slow to no moving drains. After having the line snaked twice in less than a week, I decided to try something to clear the gunk out of the line. I poured half of the bottle in the back shower and the other half in the front shower. After letting it sit overnight, I poured boiling water down the drains to flush it. It started to back up but less than a minute later everything went down the drain. I let the hot water run in the shower for about 10 minutes and the drain was clear. Will use this once a year from now on to keep the line clear.
Pros: Reliable, Easy to Install, Good Instructions
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.
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!!
Pros: Durable, Easy to Use, High Quality, Good Size & Weight
My problem has been a slow draining line that was evident when the washer was draining. It would back up & overflow onto the garage floor. Several years ago, we rented a power drain auger from Home Depot which bored thru the build-up (which looks & feels like soft rubber) & alleviated the problem. This time we used this product overnight. Our drain line is linear thru the house. One half gallon was put in the shower drain at one end of the line. The other half was put in the washer drain at the other end of the line. The next morning we flushed from both ends with hot water for 15 minutes. The problem no longer exists. We saved the extra gallon for maintenance cleaning as needed.
I have about 100 feet of teracotta pipe as a main sewer line running from my house to the city sewer line at the street. I've had to snake out this main line several times a year to keep it open. Because it's old, it's subject to roots entering at the terracotta joints and grease build up from the kitchen. I have an outside cleanout right where the mainline exits the house. I used this product exactly as directed....at night, following all the safety precautions. The next morning I ran hot water down the disposal for five minutes followed by pouring 2 gallons of boiling water in the cleanout where I put in the Main Liine Cleaner the night before. I have an additional cleanout halfway between the house and the street where i can look straight down and see the speed of the water flowing form the house to the street. I was delighted to see after one treatment the water was moving about three times as fast as I've ever seen it. I've lived with these lines for over 40 years so I know them pretty well. To say the least I'm happy with this product and will retreat as needed.
This stuff is liquid gold. I had a back up in the sewer line. Water from the washing machine was draining up into the bathtub. This happened about 10 years ago and the cause was tree roots and the result was a $400 bill from the plumber who had to snake the line. Last night before going to bed, I applied the product as directed and then flushed with hot water this morning, 8 hours later as directed. The line is totally clear! I have washed a load of clothes, taken a shower, and flushed the toilet, with no back up! It is amazing that I have dodged the bullet for just a few dollars. Instant Power will become part of my sewer line maintenance program.
Pros: Easy to Use, High Quality, does what it says it will do
I picked this product up from home depot on the recommendation from a store employee. Did not work. I poured it down the tub and sink. Waited the 8 hours and tried to flush and wash clothes again. No luck. Everything backed up in my tub again. Funny bottle says email or mail receipt to us and we will refund your money. Well, no information on the bottle to do so.
I've used this product before and it worked well. However, for my latest problem it didn't work. Instructions say use a second gallon; I did. Still no go. I would give it a higher rating except that I followed all the instructions for a refund and never received a response nor a refund. It's been over four months since I sent it in.
I've had sewage back up issues in the basement of my rented house for the three years I've been living in it. I've rented snakes, called plumbers, and spent several hundred dollars. I was researching alternate approaches and come across this product. It had good reviews and was guaranteed, so I took a chance. I purchased one gallon and poured it in the backed up water with little hope. I came home from work 8 hours later and nothing had happened. I then poured a second gallon. Five minutes later whatever was blocking the drain broke free and the water drained freely. I hosed off the floor, ran the dishwasher, ran the washer, and took showers. There was no slow drain or back up at all. I was running out of options and this offered the best results. The cost was $21.50 total. Man, what a huge load off my mind!
I was sorry that Main line Cleaner didn't work for me. I had to go to home Depot and rent a Drain-Cleaning Machine for $40, which still beat Roto Rooter's price by $429. I applied for a refund from Scotch Corp. and received the check in less than a week. Any company that honors their guarantee that quickly will get my business in the future. Give it a try, what have you got to lose but a few hours.
We tried this product because of the reviews it received and the fact it was the cheaper way to go. We had sewer back up with slow draining. Six months earlier we had the some problem. We rented a snake for the main line but found nothing blocking it. We used a sink snake in the floor drain and heard a pop and it was draining again. When it happened this time, I looked online and found this product. Since it promised it would work or your money back, we decided to try this first. I bought 2 gallons used one as directed and waited the 8 hours. Starting running water and some came up again but it did drain faster. So we thought we would use the last gallon and wait another 8 hours. We are so glad we did. The drain is running like it is suppose to. We have come to the conclusion that our problem is soap scrum build up. We are planning to use this product every couple of months to keep the drains running clear. I am so glad we decided to try this way first. Less money, less work just needs some time to remove what it took months to build up. With the money back promise if it does not work, you have nothing to lose but some time trying it.
We had a complete blockage in our decades old sewer line. Spent hundreds on a plumber and with their 200 foot snake and a blow bag were only able to get the water flowing a tiny bit. We were advised to resolve the clog we would have to hire someone else to dig up our line.
I was trying to figure out how I was going to come up with a few thousand dollars out of thin air when I found this product on the Home Depot website and saw so many reviews where people had a similar issue like mine. I decided to get a couple bottles and try as a last resort.
We used the product that night and did the hot water flush the next morning. The draining was still very slow, but since it says two applications may be needed we tried it again the next night. There was a noticeable improvement by morning and by afternoon we were able to have the showers running again without anything backing up at all. In fact, things seem to be draining better then ever!
Like some other reviewers, I went into this with low expectations in terms of what the product would really be able to do for the extremely slow main line in my house. I began with a drain snake, not expecting much from it either, but pulled out several large clumps of tree roots. The rate of drain was unaffected however. One full bottle of Main Line Cleaner and 5 or 6 hours later, and the drain was running normally, able to fully evacuate my rather full sump pit without blinking.
Even if you doubt it, this stuff is entirely worth taking a chance on for the price. Give it a shot!
This product was a surprise. We have a septic system, and we get clogs maybe 3 out of five years generally in the main line out to the septic. Water was backing up into the house, and I was going to call a plumber but figured I would try this.
Dumped this in the drain on the way out of the house, and let it sit over night. Flushed with boiling water in the AM, and the clog was gone. I was skeptical so we all took showers, flushed the toilets, and realized the problem was gone.
I am sure we will require a plumber at some point in the future, but this works for clogs involving toilet paper, hair, and other gunk. Certainly worth the $10 price tag as if it does not work your not out much. I am going to use it 2-3 times a year to try and keep the system clear. This was a nice surprise!
We have had main line sewer backups from the past four years having to call out a professional plumber several times a year at a cost of $250 each. I read about this product and thought I would give it a try - I mean $11.95 or $250 so what could it hurt? I can now say that I am a proud advocate for this product. It can do things that my plumber has not been able to do. After using this product, our main line had more water flow than I can ever remember. I absolutely support and recommend this product for anyone having in home line trouble or outside main line trouble - you will not be disappointed.
One year and 9 months after having my main line snaked, at a cost of $180, my main line started developing a blockage. Whenever I did laundry, the line would start backing up. I bought a gallon of this cleaner and poured it down the clean out opening. After waiting 8 hours, I flushed the line first with a bucket of hot water, then about 1/3 of a bathtub full. Now the main line flows normally again.
This is a wonderful product that works and will save you real money. Highly rec'd!!
Pros: Easy to Install, saves big maoney, guaranteed to work or $$ back.
I have a main line in the floor of my basement that has caused me troubles time and again. I have tried Roebic main line cleaner and had the drain snaked before. I bought this, somewhat skeptically might I add, and poured 2 gallons of boiling water into the drain the following morning. Voila! Clear as can be.
