Hi, Guys
Since my Yak had been dormant since October, I wasn't particularly alarmed when preparing for the first fire-up of the year I noticed the emergency air bottle had drained as empty as the main bottle. Although I didn't recall that happening last year, I figured it just all bled off from being down so long. But now both bottles are nearly depleted after just a couple days when I refill. Obviously there's a major leak somewhere. What I'm more interested in is why is my emergency air venting? When the main bottle emptied in the past the emergency bottle always remained at 100%. Does that mean a shuttle valve is mispositioned? Leaking emergency valve? I went through all 3 shuttle valves and actuators last year as well as the "equalizing valve" in the rear floor. The system was pretty tight when I parked it last Fall. There is no audible hiss - and my airport gets pretty quiet at times. Still battling compressor issues, but....one thing at a time I guess. Anyone who's "been there" and is willing to share would be most appreciated.
Thanks!!

Check for a leak coming out of the external air fill port after you refill the bottles. It very well could be some crud inside the main and emergency check valves causing them not to close properly.
