Gallo Drain Gun – AC Drain Line Cleaner Tool With Flexible Hose Pipe For HVAC Clogs - Includes 6 co2 Air Conditioner Drain Cleaner Cartridges

Did what it's supposed to. My ac drain line was severely clogged. The drip pan was filling up daily. Product cleared out the drain line, ac has been running without issues. Product is easy to use.

I have an in-ceiling AC in the bathroom of my condo. The main drain line goes behind the shower and drips without notice. When that line gets clogged the overflow drips directly into the middle of the shower. It's gross and annoying and something we deal with every summer when the temps rise. I've tried various methods to clean out the main line each summer from brushes, tablets, bleach, vinegar, but this place was built in the 70s so it's an uphill battle. This summer the overflow drip got REALLY bad and I couldn't stand it. None of the other methods were working so I started looking for new options. I didn't want to hire a plumber to blow out the line for $200 so I looked for something I could use to do it myself. I found this little air gun and decided I had nothing to lose. It did take a couple of capsules to get it to completely clear but I am so happy with the results! The capsule does freeze up if you use it in one shot. This is to be expected but it does make it take a little longer to finish the job. Assembly of the gun is really easy and it's very simple to use. The hose and angled tip made it really easy to maneuver around the pipes and pan and angle it just right. I highly recommend this product.

Terrible product! Do not waste your money! CO2 cartridges have less than one second and are definitely not strong enough to clear any clog! Do not waste your time or money! Again I repeat do not waste your time or your money!

So……first off, I live in south Florida. Anyone reading this review that also lives in that area knows that our hvac units run ALL day long in the summer months. This is because it’s hotter than the surface of the sun outside. One of the drawbacks to my AC running all the time, is the drain line gets clogged up with really nasty, slimy, different colored stuff. Usually, I can clear it with water, but, not this time. I bought this thing without high expectations but, it cleared out my drain line in under 3 seconds. First, it’s kind of cheap in terms of construction. But just about everything is, so whatever. Second, the co2 cartridge has to be screwed into the device prior to the handle. The handle doesn’t apply enough push for the little pin to pierce the top of the cartridge. No big deal there. The execution of this thing, however, was flawless. Administered co2 down the line and cleared out about 8 inches of I don’t know what!!! If it fails the next time I need it, I’m still saying it’s worth it. I’ll drop another $30 if need be.

Came home one day and saw some water leaking out of the secondary drain line for my HVAC system. Not knowing much I called my HVAC guy who came out and said my condensate drip line was clogged. I watched him as he took a container of some type of compressed air and blew out the drain line. He suggested that I run some vinegar or bleach down the line every couple of weeks to prevent buildup which I did but I also came on amazon and found this tool. Despite running bleach down the drain line every few months, this summer caused the drain line to begin clogging again. I got this out and blew out the line myself, taking care of the issue without the HVAC service fee. The tool is very easy to use but definitely feels pretty cheap. It does not feel like it is very well made but overall it does the job and I have not have any issues with it. Would highly recommend this to anyone having issued with their condensate drip lines or even if you are not, just having one on hand would be a good idea.

Bottom line: if you are only a homeowner and want to clear your clogged drain line, take this, a PVC pipe cutter, a straight-PVC coupling, and some PVC glue and give this a shot. If this doesn't work for you, that's when you *know* you'll need a professional HVAC technician with all the tools to get your drain line unclogged, and even then, you may need to just replace the whole entire drain line if the result is a blown-up drain line.This is a tool that worked wonderfully for the first time I tried it, but a rubber gasket meant that it would leak *every* time I put a new cartridge on. That means I cannot store it with a cartridge in, or else it will be depleted by the time I need it. It's also very difficult to screw it on, even with a tongue-and-groove plier. The tool has to puncture a CO2 cartridge to use the pressure inside, and that is difficult depending on how strong the seal is on the cartridge. It works when I need it, except for the most powerful of drain lines.The most recent instance had me go through three cartridges of these things without success. Eventually, I had to grab a tank of pressurized gas (around 300 PSI) and use a drain line blowout bladder on it to blow the clog out. This happening is very rare, but that means that this particular tool isn't the end-all solution for the toughest of drain lines. You will still want a nitrogen tank around just for the stubborn ones if you're a professional HVAC technician.
