Had it fixed this afternoon. Took maybe 5 minutes. Turned out to be a small check valve on the circulation pump line, not just a straight fitting like I thought it was.
The hard plastic valve cracked halfway around where the softer plastic line connected to it. It could have been from icing, the valve is right next to the skirt. We've had plenty of sub zero nights, and days where it would barely get above zero. If I put just the right pressure against it, it wouldn't leak, so maybe its been cracked for awhile, and it finally shifted just right.
Anyway it's up and running. 2014 Limelight Flair, purchased in October.
