Tom your explanation of contamination makes sense. Here is the crazy story of my coach... I purchased right at 1 year ago. As I learned about the air systems. I realized the main air tank by the 120v compressor was installed upside down, meaning the drain valve was on top. When we recently pulled the tank to correct the situation, we found a little air in a water tank :-( it was only 2 weeks after correcting the air tank install that the solenoid failed. I have not rebuilt it yet, but suspect rust as you said.
