Elmer and Sean flushed cooling water loop over the weekend.  Flow through the system is much better.  We have been able to run 5 etches so far without any water flow problems.  
-
But we did have one chamber overpressure on the 3rd etch.  This was one of the problems we were addressing before the water issue.
-
Also, we currently can't load wafers from either loadlock.  Sean was calibrating the loading when the water shut system down.
