Finally Rested Up
I ended up being at work from 6:30 am Monday until 9:30 AM Tuesday. Someone else took over for me, and I went home. We finally found the problem around 8:30 AM using a helium test. You fill the system with helium and use a helium detector to lead you back to where it is escaping the system. I am so glad that is over, and I am so going to pull out the helium test sooner than after 12 hours of searching next time! Back to work tomorrow. Happy 4th of July!
