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

This has made life so much easier for cleaning out the drain on AC condensers.

It's def good to have your own if your job requires you to unclog narrow pipes. Easy to use and seems like it'll last forever if not abused.

No where near quality of the swoosh brand and the red lock switch doesn’t even work.

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.

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.
