ドレインガン | CO2カートリッジ4個付属 | A/Cコンデンセートライン用

Worked like a charm!

I needed an effective means to ensure that the condensate drain line for my AC unit was clear of any obstructions. The Gallo Drain Gun was an excellent choice for this job, and I was able to blast a burst of pressure through the drain line, and any residual stuff in that line was blown free. This gun will accept either unthreaded or threaded CO2 cartridges, and mine came with six threaded ones. Be advised though, that once activated by the trigger, The CO2 pressure only lasts about 3 or 4 seconds, so you need to hold the hose & adapter firmly against the end of the pipe you are unclogging. One thing I would change, is the tapered rubber hose nozzle. While it will work well with 1/2" and 3/4" pipe I.D.s, I really had to carefully align it to work with my 3/8" O.D. copper drain line, since the end was too large to insert into the approx. 1/4" I.D. of the copper line. The next time I use it, I'll insert a mini-funnel into the open end of that 3/8" line, and that should do the trick. All in all, I'm very happy with this unit!

This is the worst piece of garbage that I ever purchased from Amazon, which almost always has great products. Not one of the 6 cartridges punctured properly and didn't have enough power to do anything. I watched the video several times before using the product. It is a very simple concept but it just didn't work! Obviously I still have a clogged line.

The product is good after using 3 cylinder it’s not working now so please send me the replacement This is per your procure to replace a new one I spoke with the seller and they are good with their warranty Great service

Worked perfectly after using went outside where drain line is and could tell it went all the way through approximately 20 feet. Very easy to install and use
