Help. I’m doing my 1 mins leak test. Buddy with me stands up and moves behind me during test. He’s moving around lots while testing. Is it normal to lose air pressure beyond 4 psi? Hasn’t done it when he’s not in truck with me. I’ve heard it could be messing with the Leveller valve ?? or something else causing it?
Help!! I’ve got air loss
