Thanks Michael,

Do you have a recommendation on a check valve that I should be looking for or are the all pretty much the same (as long as they are the correct size).

Any ideas on the Air Control Valve?

By the way, I have completed my inspection under the coach, no leaks. I checked all tanks for pin hole leaks and didn't find any. Rechecked the six packs and all connections. No other air leaks that I could find except those in the compressor bay.
