Mount Everest is about 9.000 m? For this altitude the absolute pressure is about 0,3 bar » saturated temperature is about 70ºC (start of water boiling).

Hi Gary,

That sounds like a trick question. Water will freeze at 0, which will make vac system very hard. Make sure pipework is above 0 when pulling a vac, the warmer the system/pipework the better.

or blow heated ofn through the system the warm it up
