Hi there - we bought our house about 10 years ago, and the previous owners had installed an underground irrigation system. I recall seeing the valve box in the yard (green cover), but now grass has grown over it, and over the years I've forgotten the exact location.

Every year I think about trying to locate the box, but i've admittedly just put my head in the sand and have chosen not to think about it! I feel like a irresponsible owner! Luckily we haven't had any issues with the system, but I think I should locate the valve box anyways.

Any suggestions? I've thought of walking up and down with a sharp stick, and poking every few inches in the yard...
