Leaks are tagged and the location of each is noted and included in a report. An approximate dollar value is assigned to each leak so that justification can be made for repair of the system. A systematic program of repairing the leaks should be implemented as soon as possible, preferably as the leak survey is performed. A leak survey usually identifies the most common leak areas:
Compressed air leaks can be very costly. The charts below show typical costs associated with leaks of various sizes.
