You don't have to lie to get your answer lolI have a brand new Across International vacuum chamber and a Yellow Jacket 15-micron 6 CFM vacuum pump and for some reason I cannot get more than -25.1 inHG ( -.085 MPa, or -12 PSI)
Ive left it on for 8 hours and it wont budge past that pressure point. Need help, i have like 2,000 grams to purge
