OK, I've started my test run with my WC rig, and I have a few questions. In certain areas it 'feels' like the water isnt flowing, but when I clog it (via making an uber kink) the pipe becomes clear instead of foggy [Its probably foggy because of my additives]. Is the water still flowing, or is my paranoia justified? Does it matter which barb I plug the outflow / inflow into the heatercore? How about the reservoir? I'll upload a picture of the test setup in a little while to help give everyone a better picture of it.
