What really worries me is that i did the "radiator dance" with hot tapwater and poured it into a white plastic bowl to look for gunk and then ran each rad with the pump and res combo to check for leaks before putting it in the case. At that point i ran it with LCMS grade MilliQ water... Maybe i should write EK support to see what they have to say about it...
One should never flush a Radiator with tap water for two reasons.
First you could burst your Radiator. Not all systems put the same psi out of the tap.
Secondly, it's getting to where tap water brings with it, high mineral content. My washing machine tub is coppery in color suggesting a high Iron imbalance. You'd be better off not flushing at all. No I don't and am not recommending that. Just pointing out that you're removing one or more deposits from the radiator, only to introduce another one or more deposits in place of that.
5gal bucket or twp, flex tubing and a filter of some sort that can catch smaller microns a spare pump. Connect the pump to the inlet from one bucket then run the next tube from the radiator to the 2nd bucket. Fill the pump bucket and watch the magic happen. Make sure to prime the pump and don't let it run dry.
