all steps above to prepare for gauge monitoring test
CLOSE
both cylinder valves turning clockwise
MONITOR
gauges on both regulators for five minutes
If the readings do not change, the test is complete. If any readings change, there is a leak on that side of the system.
Follow gauge leak analysis to diagnose
