Donald has made some valid points here but I would question why it takes three days for this system to pump down to 1e-6. This system seems to me to be suffering from some other malady. Have you had a leak detector on it, or, better still a RGA, to find out what is in this system?

Regards and, as always with Vacuum systems, good luck.
