DiversitechGG-1 Drain Gun with Flexible Hose Pipe for A/C Condensate Lines, Air Conditioner Cleaner, Clears HVAC Clogs, Charcoal Grey

Professional hvac tech here. It works great when nothing else does. It EATS CO2 though so be ready to blast 2-5 cartridges for hard to get clogs. Buy them in bulk. They pretty much are just one short blast per cartridge.

👍👍👍👍👍👍👍

The product listing doesn't specifically mentions that it doesn't come with at least one cartridge.This is one of the more scammy listing's I've seen on Amazon.Also, as others have mentioned, it doesn't seal the cartridge correctly.Will be returning this.AVOID!

Didn't have any issues. Easy to use. Worked to unclog my condensate line.

With this product you can save money by blowing out your own drain line. Saving you a service call as well as other fees for a simple procedure!!

I’ve had lots of problems with clogging of my ac condensation pipes and this tool allows my to blow out the clog and keep things working properly. It’s the same thing the pros use - so this saves me a lot of time waiting for service visits and of course the cost of DIY is much better! After I blow the lines I follow with a little bleach to keep these clean. I do this once a month during the summer.

The lower cartridge housing cracked after only a month of use. Not cool. Especially for what they cost…. #diversitechgg1draingunfail

Works as designed , an essential

Bought 2 units, both leaked out the entire cylinder in less than a minute. The original version was far superior. Not recommended.
