Boiling Water at 70 Degrees F

I was able to boil water at 70 degrees F today.  This is the first test to see if the pump can reach appropriate levels of vacuum. 

Once a few bubbles rose to the top, the water broke into a vigorous boil within seconds.

It is important to note that the chamber pressure will not go lower than the pressure required to boil the water.  The boiling of the water replaces water vapor being evacuated form the chamber.
