Been using this product for years now. Pour this down your AC drain once a month and it will never freeze over

This stuff really works! Clogged ac Line that runs into the bathtub. We tried everything. Shooting a CO2 cartridge didn't help at all. Put this stuff down the line , then flushed with lots of warm water and a couple of hours later followed with using the drain gun again with the co2 cartridge. A huge amount of dirt and water literally shot out of the bathtub drain. A big mess but so happy it finally unclogged. Will use this monthly from now on to avoid major clogs.

Keeps your AC line clear of gunk that makes it stop working. Use snout every 2 months in a regular basis and it should eliminate concerns related to drainage if condensation from ac unit. Easy yo use and cheaper than a service call.

My AC repair professional recommended this product instead of using chlorine or white vinegar. We tried bleach and vinegar but they didn't clear the tube. This stuff did the trick. Be careful not to get it in your eyes or on your skin.

So far so good. I know it kills the grass, but sometimes you have to sacrifice.

It's amazing what this can do for your drain line.no need to vacuum the standing water out at all.just pour a bit and in seconds magic happens you will see the water drain down all way instantly in the pipe.i have tried many others bottles out there they claim get the job done & failed.Drain Solve is the leader #1.

I tried 3 other liquid AC condensate drain cleaners before this. They never unclogged the drain completely over 2 years. But this stuff did the job the first use. Southwest Florida is a very humid mold and algae environment and drain lines can clog up almost overnight, not to mention critters that like to crawl inside and get stuck. My 3hp wet vacuum could never clear the line after using the other additives. I absolutely 1000% recommend this Drain Solve for clogs. No odor. No damage to schedule 40 PVC drain pipes. Good value. And you won't find it at any national home improvement stores.
