Drain Line Cleaner for A/C Condensate Lines Starter Kit with 4 CO2 cartridges

No complaints. Other than the cartridges are screw in. Some I've used are the base screws in and therefore punctures the cartridge. This one you remove the base and screw the cartridge in then reinstall the base.

Used for clearing clogged a/c condensate drain. Worked like a charm!

If you'd rather keep your nitrogen rig and hoses in the t.Make sure you have the cartridge threaded all the way in before pulling trigger.ruck, this little gun my be an easier way. Keep in mind this works best with residential size drains, the rubber end piece will fit 3/8 to 3/4 in openings and its rated at 800psi. I've found its important to make sure the red"O"ring at the base of the top piece is not crooked or rolled, you won't get a good cartridge seal unless the O ring is perfectly placed. If you can borrow the curved back cleanout piece that is packaged with Rector Seal SS1 safety switches, it works very well with the rubber cone on the end of the line. Overall construction seems good, fittings and hoses look robust.When buying new replacement cartridges, make sure they are the 16g threaded cartridges.Some company's don't like these, some company's will reimburse you for the cartridges so check with your office.I would recommend when reordering to buy more of the cartridges than you think you need, and when using this, always grab and extra cartridge or two from your truck just to have handy.

I used it to blow the condensate drain line on my ac unit. My drain line is about 40’ long and the co2 cartridge just does not have enough volume/pressure to push any slime out of a long pipe like this, even when the seal to the front end of the pipe is good.

This is super easy to use, I had a HVAC problem and I faced time my brother and was able to get HVAC line unclogged by myself by using this product. No HVAC experience. Awesome

It's strong enough to blow a wad of hair or something light out of a 1-1/2" diameter water pipe. I didn't know that 1 cannister = I full blast and then it's empty, but it comes with several cannisters, so that's ok. We'll probably use it once or maybe twice a year. It's good enough for what we need.

Lacks power, easily broken plastic housing

I first seen a device like this being used by an AC repair man. I ordered this to try to maintain my new AC unit myself. It's works great. Just like the pros.
