What Customers Are Saying
The product has mixed results in unclogging drains and pipes. Some customers found it effective at clearing clogs with just one application, while many others reported it was ineffective, even after multiple uses as directed. The product seems to work better for minor clogs rather than major blockages, with results varying greatly depending on the specific clogging problem.

Would RecommendBought this to ensure some type of blockage in my main inside sewer line gets better and not worse (if the problem is built up sludge and not structural issues). The Line Cleaner is easy to use. Just pour some down the fixture at at the very beginning of the sewer line and let sit overnight for several nights. Easy. No problems doing so. Does it work? So far (a few weeks), I have no evidence that it is not working. Hard to prove something that you can't see. I will have to wait for proble...

Main Line is great. I have a drain in the center of my garage floor. It sometimes will freeze in the winter and overflow, which can be dangerous. it also fills up with in the spring or summer after a lot of rain. It worked great. Follow the instructions.

Works!
Used regularly, as instructed, this product works. It keeps the bellies in my main sewer line clear. Much better solution than hiring a plumber to do a high pressure blowout.
Main Line really works
Would RecommendI use it every quarter and have for years when we had a backup problem from rain the plumbers snaked our pipes and they had no sludge. They were surprised. This stuff really works.
Excellent results
Would RecommendI have a driveway drain that catches dirt, grease, leaves and basic street run off. I used two containers of Main Line at 11 p.m. and by 7 a.m. the drain was flowing and totally clear. Good Job Main Line.

Fixed my kitchen drain
Have been using this regularly now to maintain the drain from my kitchen. The drain was running slow again, after spending hundreds of dollars with a specialty plumber several months ago to blow the drains out. There are ”bellies” that tend to fill up between the house and the street. This product has corrected my problem so far. I will be using it regularly from now on to avoid calling the plumber!
