I'd say drain it. Left my fist ever water cooled rig at my parents house for a couple of weeks whilst on honeymoon. When I returned I had to strip it down and clean the blocks and renew the hose. It was a total mess although I dont know what caused it. Distilled water with a UV blue dye. Can only put it down to the dye. One of the reasons I dont use anything in my water now other than a silver coil.
