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.

  • The RedRock Kit is a necessity to use on a monthly basis. The kit is a great value for the money.
Color: Red
RedRock Gallo Drain Gun AC Drain Line Cleaner Tool is an absolute to keep the HVAC Drain Line Clear. Our inside AC began dripping even though we cleared it with a cup of warm vinegar every month. After investigating the AC system, we researched the problem on the internet that led us to Amazon. I am very happy with Amazon as we watched HOW TO videos and ordered the Condensate Blaster. It arrived the next day. With one use, the blockage was released and our AC is running fine now . I am glad we ordered the five cartridge kit as we will continue to use the Red Rock Gallo Drain Gun AC Drain Line Cleaner Tool once a month. The kit is easy to put together and easy to use. This tool is more than worth the cost as it saved us over $200 for our AC man to come out and do what we did! The kit keeps the blaster and cartridges together in a durable package. The tool is small enough to use it in a tight area. It is made of sturdy material that is necessary for the strong blaster. ... show more

  • Drain gun works!

This is easier to use than I thought. It works well and it took care of my plugged A/C drain. Thanks

  • Not strong enough to do anything. Total waste of money
Color: Black
Would leave 0 stars if possible. An absolute waste of time and money. Used all 5 cartridges and managed to accomplish nothing. All the carts worked, but the amount of pressure they generate is FAR too low to do anything. There is no way these can blow out any clog and anyone that claims otherwise is misleading you. These are not strong enough to do anything. Great idea if all 5 carts were consolidated into a single burst, but each single cartridge will not help you. The good news is you wont need to order replacement carts because the whole kit will be going to the landfill. What a waste. The rubber end wont fit into a normal drain line, it is too big. Just what a waste, I feel like a sucker for even trying this nonsense. ... show more

  • This would work on a minor clog.
Color: Black
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

  • A Handy Tool for Clearing AC Drain Line Clogs
Color: Black
Living in Florida, keeping the A/C drain line clear is part of regular home maintenance, and this tool makes the job much easier. The Gallo Drain Gun is simple to use and provides a quick burst of CO₂ to help clear minor clogs from the condensate drain line without having to take everything apart. The kit comes with several CO₂ cartridges, so you have everything needed to get started. The gun feels well made, is comfortable to hold, and the cartridges install easily. It's much more convenient than trying to clear the line with makeshift tools, and it can save you from dealing with water backups caused by a clogged drain. If you live in a humid climate where A/C systems run frequently, this is a useful tool to keep on hand for preventative maintenance. It's a worthwhile investment for homeowners looking to maintain their system and potentially avoid unnecessary service calls. ... show more

  • Works. Loses Pressure Really Quickly - So Be Fast.
Color: Red
It works. Just make sure you have everything apart and are ready to use it within seconds after screwing down on the cartridge since it will start losing pressure pretty quickly. I would also recommend wearing gloves to avoid any kind of accidental "freezer burn".

  • Works, but finding the proper refill cartridges is next to impossible...
Color: Black
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
