GGC-12 Swoosh CO2 Gun Cartridges, 12-Pack, Silver

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 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.

We bought these cartridges to use with a drain gun. We used them to clear a blocked drainage pipe that drained the water away from an A/C overflow/drip pan. The tool and cartridge worked first time and saved the cost of calling out an AC repair man. That means, even allowing for the cost of the tool and the cartridges, we saved around $100, and in future we will save a lot more.

These work best with my old Gallo gun/tried other cheaper brands & didn't fit correctly. They are a little pricey/otherwise would be 5 star.

Item packaged well all there look well made not used any of them yet but will update review once used.

Comes in handy don't have to call the hvac technician all the time

I was able to clear my A/C drain using these with the Swoosh gun they are made for.

Before I bought these I was calling my HVAC company every few months to clear a blockage and they gladly took my money. A friend recommended these to me and I blow one cartridge into the line every other week and haven’t had to call my HVAC company even once to get system back online in the two years I’ve been using these.

Loved the product.....but due to border restrictions I was unable to receive the product.
