Anyone familiar with water meters ? UPDATE

I dug a 4' hole thinking it was my sprinkler junction that was leaking and found no wet soil or leak .
I did have some water in my crawl space but it had been raining and snowing hard for a few weeks so it was difficult pinpoint the cause . That is what prompted me to dig up the sprinkler feed . It is right next to the foundation where the main lin enters the house. I will go back under the house and check it again today. But at a rate of .5/gals per minute I should have 4' of water under there after 2 months !
