But if I seal the res. and the water will overflow it, when I take the refill hood of, then a refill wont be possible at the res.!!! ARG!! So I MUST place the res. at higest point, or seal the res. and have an air trap right ?
Never thougt there would be that much trouble!.
But hey....see the koolance system...they have it "my way" with rad. high and res. low....WITHOUT AIRTRAP! ... How ?
