Features

  • THE ORIGINAL GALLO GUN - The Gallo Gun is a lightweight portable tool designed to blow out condensate drain lines instantly. Simply insert an included Gallo Gun CO2 cartridge into the Gallo Gun and with a press of the trigger - 800 psi of oil free air clears the line.
  • LIGHTWEIGHT AND PORTABLE - The Gallo Gun packs cleaning power into a small, lightweight package. This prevents the need for carrying heavy air or nitrogen tanks.
  • AIR POWER - The Draingun uses CO2, eliminating the mess caused by water back flushing drain lines.
  • ENVIRONMENTALLY FRIENDLY - The Gallo Gun uses carbon dioxide (CO2), a common component of air, and is totally safe for use in the environment. The Gallo gun is a wonderful alternative to the environmentally unfriendly practice of using refrigerant to clean the drain line.
  • FLEXIBLE HOSE ASSEMBLY - The flexible hose assembly enables you to maneuver through cabinets, coils, and hard to reach drains.

  • Great for a/c drain pipe clogs
Color: Gray
Worked excellent on clearing condensation A/C line in my home. It was really backed up, drip pan would get full multiple Times a day and wet vacum was not cutting it. This stuff really works for diy- ers. We cut the pipe, didnt use spout that comes upward, didnt want product to accidentally go into the unit. Then closed it with a coupling pvc pipe (didnt seal it in case we need to do it again next year). Be aware after cylinder is used it will be extemely cold. Do not touch with bare hands, leave it in the container until it cools off- then remove. ... show more

  • Works well
Color: Gray
Easy to use and surprisingly simple design. Been cleaning out my condensation line for a few years using this and no problems so far. Did run out of cartridges though so I bought some more in bulk.

  • Won't penetrate cartridge
Color: Red
Do not buy this thing! I bought it to unclog my a/c drain and it worked once and then crapped out. The first cartridge was perfect, worked great. I went to blow a second one through the the line and it barely did anything at all. I thought, ok, maybe a dud. I tried a third and got just a hiss and a cold cartridge. I looked at the cartridges and the actuator wasn't penetrating them enough to do anything but just barely let anything come through. I went in to do a return and it says non returnable and non replaceable. That's convenient. Look for something else! ... show more

  • Works like a charm
Color: Red
Worked like a charm. I had been using a shop-vac to try and unclog my AC line to no avail. I was about to give in and call my AC guy when I stumbled across this. Immediately ordered. As soon as it was delivered I followed the step by step instructions on the package. Only took one single cartridge to unclog the line. There was so much “gunk” that came out it was crazy, no wonder water was backing up into the pan. 10/10 recommend. ... show more

  • This would work on a minor clog.
Color: Gray
This did not work for me but would probably work for a minor clog. This AC condensation line was in such an awkward place and too small for a regular snake I ended up having to cut a section of pipe with the clog out altogether and replace it. This clog was thick and hard. So I don't think this gadget stood a chance. ... show more

  • It simply worked for my drain - cheap, but to use occasionally, perfect
Color: Gray
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! ... show more

  • Works, but finding the proper refill cartridges is next to impossible...
Color: Gray
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!! ... show more
