I recently had all my mold inspection stuff stolen out of my vehicle. I bought a new/used pump on Ebay(see picture) and it seems to run great, however, it doesn’t want to go all the way to 15psi. I can twist the pressure knob and make the pressure/suction drop down to nothing but then when I twist it to go back up, it always stops at 10psi.
I really don’t want to waste the time or money on sending it back if there’s a way I can fix it myself.
Has anybody ever run across this problem? Is it possibly an adjustment setting causing it to stop at 10psi or is it some sorta defect within the pressure gauge?
The pump didn’t come with any directions or pump settings info so I was wondering if any of you might have some experience with these pumps?
