What a day: I started out up front tracing the blue plastic air line coming from the 110 compressor. I got all the way back to the wet tank and I noticed the top of the wet tank had a check valve, Hmm so I stopped there and figured I would replace that as I did the 2 front tanks. Most was under the impression that there was no check valve on the wet tank I kinda thought why not, so it turns out there is. It is connected to a T with air lines on both ends. Well I put a wrench on that bugga and broke the T right off the tank. Oh s--t now what. Call someone? The coach is up but won't stay up gotta work fast so I fought to get the other lines off and drop the tank planning to go to town to get necessary check valve and fittings. Was able to remove th broken nipple from the tank. Well you know how it is when you go to Napa to get something for an emergency. We don't have one here but in Summerton there is one. Off to Summerton I go. Got back and the drivers side was all the way down while the passenger side was still up. Believe me when I say it was a very tight and trying time getting it all back in place. Starting at 8am and finishing around 3pm. So fired up the coach and raised it back up to get back under to check for leaks. all was ok. But that was not the source of my leak, Hmmmm. So continued to chase that blue line back to the engine compartment noticing that it elbows in to the main feed line from the compressor. But wait, is that another check valve? And is there a possible check valve in that elbow?
See Picture. So it seems that the 110 compressor runs direct to the inlet line at the dryer so it goes through the dryer before going out through the heavy black plastic line then into the wet tank. Will dig into that/those check valves in a few days, hoping that that is where I will find my leak!!!!
So does anyone think there is a check valve at the blue compressor line? Blow up the pic it looks like there might be and wouldn't that be necessary to stop any back pressure to the 110 compressor but there also is one at the compressor so maybe not. I will find out soon.  Yea I know about putting blocks under the coach. Also had a full tank of air, oops. I knew it did not control the air bags.
