RedRock Gallo Drain Gun- with 5 Unthreaded CO2 Cartridges for A/C Condensate Line - Air Conditioner Cleaner Blaster Opener Kit with Five Cartridge Clears HVAC Clogs

I followed strictly the instructions and it unclogged perfectly my HVAC drain lines. Worked perfectly, problem solved!

Worked as described. There is no way this will burst a drain pipe. It does however have enough pressure to unclog most clogs. I poured bleach and white vinegar down the pipe, then used this to blow the small clog out the pipe. Had to use a couple CO2 canisters, but well worth the price over an HVAC tech!

If you are like me sometimes I jump before I look. In this case I had an in expected problem on a very hot day when my AC decided to stop working, so what do I do? I grab my phone go to Amazon search for the solution and I order something that has a lot of reviews. Unfortunately, this product has a lot of bad reviews that I did not see it does not work and cannot work work as there is not nearly enough gas in one of the canisters to clear a line in your air conditioner, the company knows this and yet they won’t return their products don’t buy or you will be sorry too!

Does excellent job. Last time I had an issue with blocked pipe I called somebody, and they used exact same pump and charged $175.00 for uncloging. This time around I orderd this pump and after using 2 air capsules the pipe is workig great.

It worked well, even though the rubber cone-shaped nozzle was a tiny bit small for our drainpipe fitting, The instructions were very brief (with no diagrams) but with careful study we figured out what to do. We only needed one cylinder to clear the line, using repeated "squirts" of compressed air. A lot of white gunk came out, after which we poured about a half-gallon of water through the line for good measure.

Easy to use

Why did you pick this product vs others?:Product is well priced and I had good luck with it clearing my condensate drain line. Looking ahead, I am having a horrible time ordering the correct refill cartridges for this device, and Red Rock is less than helpful in recommending a working CO2 cartridge solution. I've been sent around to multiple people in the company, only to finally be told that I need to call in for the proper reference cartridge. Bogus. Make ordering refills easier!! Buyer beware. This gun will NOT accept threaded cartridges. You need a 16oz, non threaded cartridge, and it needs a long neck or will NOT work. While I'm happy it worked, it took 3 of my 5 cartridges to do so. If nothing else, I plne to just use the hose and rubber stopper to hook it up to my air compressor in the future and just throw this away when I run through the other two cartridges. Also, FYI - if you order the wrong cartridges, they are NOT returnable!!

Phenomenal! Blasted the clog in the condensate drain and water began draining as it should. Great too highly recommend.
