Richard,
If cold weather can make fittings leak then that may be part of my issue as we have been cold. Not sure why the push connectors failed as I am just not that familiar with them & how they work. The check valve on my compressor has a hose that goes out the bottom of the coach. It has leaked air before when rust from the air tank got stuck in it. It is not leaking out the hose now though. I will bypass the compressor as you suggest, pressurize the system & check the check valve as you suggest. That will allow me to see if it is leaking back into the compressor and I'm not hearing it there, right? Thanks for the idea!
As a side note: My experience is that "no two Newells are alike". I spoke with Tuga about his air tank in the RF compartment on his '99 Newell and he doesn't have one. His coach was built not that long before mine. I'll inquire from Newell why mine has that particular tank and what it serves.
