I've got a brand new heatercore that I've just modded to fit my 1/2" ID tubing to, and I want to flush it out to make sure there is nothing inside that might flow out into the loop and ruin my pump or clog up my block. Shaking it around I don't hear anything inside, but I really don't want to take the chance.

I assume I should flush it through both ways (intake to out and out to intake) a couple of times just to make sure, but my question is what should I use to flush it with? I don't want to connect the full loop back through the intake of the pump, because if anything does come out I dont want it getting into my pump, but at the same time I need some flow to keep the water moving. I think my only option is to connect tubing from the faucet to the pump and then the rad, and just have all the water dump into the bathtub or something, to insure that if anything does come out it doesnt go back into something that it would cause harm to. The only thing I am cautious about is what regular tap water will do to the inside of the copper core when flushing it. I'm sure that some water is going to end up getting stuck in the core, but I don't really want to risk galvanic corrosion. Should I maybe just get a couple gallons of distilled water and feed that through the pump/rad? If so, will there be enough force to keep moving the water through without any flow to keep it going?
