DiversitechCorp 16G CO2 Drain Gun Cartridges GGC-12, Silver, 12 Pack

Worked perfectly to blow out the gunk blocking my ac drain line. Took 6 cartridges to get it all out but much easier then dragging out the wet vac. Do wish it had different sized heads to fit the pipe a little better.

Great stuff to have to service the AC line!

These powerful co2 cartridges really work to clear out my ac drain line. I have been using them for years with impressive results. Ac drain lines here in South Florida can clog up pretty bad and the result is water on the floor, I'm my case the garage. If I clean out the line every month there are no problems. Also, two or three times a year I pour a cup of distilled white vinegar followed 20 minutes later by about a pint of tap water into the fill tube and my water issues are pretty much solved.

Worked great for blowing out my ac drain.

Works

very easy to use, take care not to overtighten the top or you can crack it

Would be nice to try it out, since I bought them for work, but that's hard to do when it doesn't come with a single cartridge. Better off buying one of the other brands that cost the same and actually come with cartridges.

Perfect choice to clear small drain lines in the restaurant and food service setting!
