Nu Calgon-4165-24 Drain Solve

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.

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.

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.

Great stuff.

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

My plumber put me on to Nu Calgon Drain Solve. It is by far and away the best drain cleaner on the market. It’s a more expensive but you can hear it working clearing out the gunk and as far as I am concerned it’s well worth the additional cost. Good stuff!!

It does the trick to unclog the drain lines for the A/C.

Use this product at work and home. Best drain clearing product ever!
