we bought this house and the lady who owned it before us had the lawn resodded 3 times. now she's gone, there's no telling who installed the sprinkler system, and i can't find the water shut off valve. i also can't find any of the solenoids(sp?). parts of the back yard stay wet all the time even when it hasn't rained for a long time. i'm guessing either a stuck solenoid or a leak. either way i need to find the water shutoff and digging up the yard is not an option. any ideas how to find the water shutoff valve or should i just bite the bullet and pay a professional to do this? thanks, bo
