Hello, I want to plant a tree near our front door and I have encountered an old pipe with a red and white wire in it. Not sure what it operates. Maybe there was some sort of night lamp next to the driveway? Anyhow, I did a real good job on the pipe, which is brittle. The green funny is part of the sprinkler system. The brown pipe with the wires in it is angled toward the stone bench on the porch, and otherwise heads out into the yard. There is a water meter way out near the curb, otherwise I have no idea what the wires do, if anything. Any ideas anyone?
