Usual crock from you. (A) Explain why a pressure gauge on a quick couple does not indicate the status of the main line, And (B) You must walk the site in bare feet. I've found leaks that a cold call walk-through never found, only a compressor and water could find the air bubbles or the noise of the compressor indicating a break.
