Hello Chris, We use a high volume air compressor starting at about 50 PSI, Walk around and listen for the "Whistle" of the leak, If not found increase the air pressure and walk it again. WATCH the air pressure and slowly increase it between walks. Depending on the age of the system and what the pipe looks like inside how high they limit the pressure to. Yes you might cause a few more small leaks to appear but the disclaimer we have the customer sign first contains wording to allow repair of those at the customers expense also.
