I was a little wary of spending $30 on this gadget, which looks like a cross-between a plunger and a pogo stick. But Home Depot had one of those videos running next to the set-up, which showed clogged sink after clogged sink giving up its precious bolus of greasy hair to the explosive force of a CO2 cartridge unleashing its entire payload at once. Watching the guy on the demo using the device, with its rifle-like kickback and puff of condensed carbon dioxide gas, mesmerized me. The next thing I knew, I was racing home with my new KleerDrain.
I could hardly wait to use it on a slow-draining sink in the bathroom. I duct taped the overflow drain on the sink, and inserted a CO2 cartridge into the Kleer Drain. I screwed on the rubber cone and then pressed it into the drain opening.
WHAM! A shower of gray grime flew out of somewhere and splashed against the walls, mirror and ceiling. I wiped the junk off my face and turned on the faucet. The water whooshed down the drain, ending with a nice sucking sound, like it was wishing there were more water it could dispose of.
I think I’m in love. Time to stock up on more CO2 cartridges. Link
UPDATE Chris sez: Just a quick note regarding your drain cleaning story. I own a device called a Profi Pipe Cleaner. It is basically the same thing, but you pump it up and pull the trigger to release the blast, rather than having to buy CO2 cartridges. It has much the same effect, as did watching the demo on QVC.
