Nu Calgon-4165-24 Drain Solve

This product works better than expected.

Worked on my condensate drain on my ac unit. Great stuff

Every few months I have to use wet/dry vac to clear ac drain in south Florida. Recently the vac wasn't able to clear the line anymore. I regularly use white vinegar and in the past used bleach. Neither really helps. Bought another drain-clearing liquid product, it did nothing. Just tried nu-calgon. After 15 minutes outside drain pipe turned into a geyser, didn't even need to follow-up with the vac. I'll be using nu-calgon from now on. Please read directions and take proper precautions. This stuff is no joke.

Our air conditioner man told us to use this. He actually unclogged our a/c drain with this product!! We'll be using this forever!!!Great product!!

This product was recommended to us by our a/c repairman. It is being used to flush out the gunk that tends to build up in the discharge water from our a/c unit that is in the garage. The fluid will wash out the buildup of gunk and discharge it through the pipes to the outdoors letting the a/c function more efficiently.

Great for cleaning AC condensation lines. Must have for any household to prevent issues.

This is the best product out there if you live in Florida and your AC line gets backed up and trips. I used to spend at least 24 hours with my shop vac attached to the outside drip line while trying to flush the line with vinegar and hot water. And then my co-worker’s HVAC person I traduced us to this! He recommended to pour only 1/4 cup down the line every 3 months. Do not follow with hot water. Works like a charm!
