Um not really a method actually dnt really check. If I think I have a leak I will just redo all seals.......if anyone does have a exact method for doing it would like to know

If you spray alcohol or acetone at the suspected leaks, the vacuum gauge will show a rise when it sucks them in.
I like our 5 year old CPS 6.2 cfm single stage. It has never missed a beat and we have used it for many different experiments, besides its duty operating a Terpenator or vacuum oven.

Yes, I am under 100 feet elevation and it pegs the gauge. It was factory tested at 65 microns and I only want about -29.5" Hg, so as to not boil away the cannabinoids.

We used acetone in vacuum casting and heat treat industry, but when the liquid is sucked into the vacuum, it boils and expands rapidly. That causes the vacuum gauge reading to rise.

If the gauge is reading -25" Hg, and the solvent is sucked into the chamber, the vacuum gauge reading should change to read something between 20 and 25" Hg. In this case zero being atmospheric pressure and -29.92" Hg being full vacuum.
