I just finished my two loops yesterday. The first loop is great other than a (I will never buy again leaky primochill flowmeter) that leaks in multiple places. That first loop runs on two pumps in the bottom of the case.
The second loop I have running on this Duel 3.2 pump/res combo you're talking about. But, for the life of me I can't seem to get it primed.
Well, it was 2am and I got frustrated quickly. I filled the res and ran the pumps but the water doesn't move and it sounds like they are spinning dry. Round two here we go.. See what I can figure out
