Step 1: How Kleer Drain Works

Picture of How Kleer Drain Works
I love this device, but it has some flaws.  First is the need for CO2 cartridges.  The Kleer Drain comes with a couple, but if you're like me, you'll use them all up in an hour or two.  Trust me... This thing is fun to use:)  

The same goes for the plastic disks, but they aren't so readily available.  The only place I was able to find them was on the manufacturer's website.  And they cost a gazillion dollars for a half dozen... And they only came with additional cartridges (which cost another half gazillion).

I think the company may be using the inkjet printer profit model... sell the printer at cost and make money on the ink.  I have no problem with that, but I don't want my fun eating up my savings, or discover I don't have the parts I need in an emergency.

Enough commiserating, lets hack a solution!
