Vacuum Leak Detection
Like any job, leak detection can be made easier by having the right tools, looking in the right places, having patience and using a great deal of common sense. Leaks can be inherent in the materials of construction, created during the manufacturing process, be introduced during maintenance or repair, or occur over time due to corrosion, wear, fatigue or stress.
The most obvious place to look for a leak is in and around the last place that was repaired or serviced. Begin by asking the question, “What was the last area worked on or modified? ” (e.g. thermocouples, power feedthroughs, door “O” rings, etc.). It is incredible how many leaks are found and corrected by simply asking questions before one begins leak detection in earnest.
