Hello, what if the checks appear to hold >1PSI, but slowly, over say 10 hours, bleed below 1 PSI? In other words, how long do the checks need to hold >1PSI to pass? Thank you!
Thanks for the question. If a check is not holding, then that is considered a fail. There is no documented time limitations. A leak is a leak, be it 5 minutes, or 10 hours.
Excellent demonstration 👏
Thank you for the compliment!
Very helpful to learn
what is the Difference between test number 1 and number 3 ?
do you close all all 5 valves on the gauge before starting Test #3?
Was this the actual test exam in Michigan?
This covers not only the exam, but in field testing in the state of Michigan.
