>By the way, I have conducted this experiment in the real world with steel pipe and significant temperature changes. I live in the great state of Georgia and I have personally witnessed the pressure increase dramatically with the control valve on the system completely closed (i.e. no possible way any water entered the system!). I have also confirmed the system pressure decrease as the temperature decreases in the same situation with no evidence of any water discharging from the system.
Sounds kind of like the problems encountered at the 2 hour test, during temp changes prior to Fire Marshal showing back up huh? R/ Matt Matthew J.
