Here's the rest of the cleaning rig:
12V power supply, washer pump and some hose and stuff...
The hose looking thing is a hose with a momentary switch on the end like on Jeopardy!... I've been hooking air to the brush line to blow the coil out in between flushings.
I'm using the carbonated water more for its effervescence than anything. The coil is about 3" thick so I figure it can't hurt having it bubble through there.
I'm getting BLACK water out of the drains. It's was like ink
