Is there a way to purge an auto of water that has got into the cylinders. This friend of mine has a press that I sold him and his chiller went out he kept running the press and now has water in the system. I warned him that he was going to screw it up and now he calls me to tell me one of the stroke cylinders was not working, I went by and sure enough froze solid. I broke the cylinder open and yes there is a rusty oily substance inside. I am helping him get his chiller going today. But wanted to know if there was a way to flush the system, or suggestion on what he should do short of replacing valves and cylinders as they fail.
