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 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
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 4 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.
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'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!
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'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.
Our septic system was acting up and had started backing up into our tubs and showers in both bathrooms. We have a 2000 model Clayton Home on a permanent foundation with PVC piping. We tried to unclog it ourselves with no luck and ended up calling a plumber out. We didn't know if the septic tank was going to need pumped or if there was a clog in the main line at that point. The only clean out we had was under the trailer and it was close to the piping in the house. The plumber ended up cutting out a section of pipe where it leads out of the side of the house to the septic tank and ran a pipe snake down it to unclog it. Everything seemed to be working fine but he installed a clean out where he cut the pipe just in case it happened again. After $255 we thought the problem had been solved, Within a couple days the toilets started gurgling and overflowing again so my husband went and spent another $20 and bought an auger and went and unclogged it where the new clean out was. Needless to say this continued every few days for a couple of weeks and we were starting to worry that the septic tank was going to have to be pumped. In desperation I started looking online and found this product. The majority of the reviews were really good and it had a money back guarantee so we decided to give this product a try instead of the Septic Shock. We bought 2 bottles just in case since that is what all the reviews said. About 10:30 PM we poured one bottle down both tub drains and our stand alone shower drain. At 6:30 AM we flushed all the drains with boiling water and everything seemed to be fine. The drains were even running faster. i still wasn't ready to claim victory just yet considering it was every few days and every time I took a shower that it would act up again. Well it's been a week and still no problems! This product was def a life saver and I'm keeping the second bottle around just in case we need to use it again. I will definitely be using this product again if we ever have another problem.
Pros: Reliable, Easy to Install, Good Instructions, No Leaks
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!
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!
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.
Had a near full clog between the laundry room/kitchen main line drain and outside cleanout....used as directed, dump and wait, overnight....flushed with hot water....I did have to do a follow-up treatment the next night, but now we're draining like the clog was never there.....
Pros: Reliable, Easy to Install, Good Instructions
I had a drain issue with my kitchen sink and washing machine backing up whenever I attempted to wash. I read about "Instant power Main Line Cleaner" and decided to give this product a try. My drain was clogged with grease and hair, pour the product down the drain waited for 14 hours before pouring "Very Hot Boiling Water" down the drain, the only thing that occurred was both the kitchen sink and the washing machine drain continue to back up and over flow. Finally, I had to call a plumber who was able to clear the drain in about an hour. I can't say if this product is good as advertised or it was a case of my drain being blocked with a large amount of grease, hair, and other small items that goes down the drain when the children washes dishes. However, I will be submitting a claim for the "Guaranteed Money Back Offer" from Main Line Cleaner.
Following directions printed on the bottle of "Main line cleaner" (i.e. let backed up water to drain out, then pour the whole gallon cleaner into the drain, and let it sit for 8 hours), I was able to fix the problem of slow flow in my bathtub with one treatment of this cleaner.
I have tried almost all drain cleaners plus snakes for drains in the past 6 months. When I really was loosing hope on everything. My husband found this product looking on line. I said try it,it cannot be any worse than others we had tried. Yes it took 2 bottles but my drain never drained as good as it does now. Only $20.00 later verses what a plumber would have been... Yes to this very good product.
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.
