Too many microns not enough pull...Lol! @the_hvac_technician offered some help to correct a members vacuum set up. Anyone that has used large diameter hoses, pulled cores, avoided gauges and installed the micron gauge on the system side, etc etc has seen the advantages. He is now the app's Chief Of Vaccum Police haha, and will challenge your set ups in a professional manner as a way to help.
