I'm planning on redoing the irrigation system in the back yard and considering extending it to cover the front yard as well. My only problem, the house is completely surrounded by a concrete patio. My best run would be from the rear beds to the front beds under about 30' of concrete. But the front beds are only 2 feet wide, so the target is pretty small.
Is it even possible to bore that distance under the concrete and get it in the front bed? Both beds are in a line and 2 feet deep. The soil is loamy with with no rocks. My method of attempting to do this would be with a water hose attached to the pipe i'm sending under the concrete. If it is not possible to hit the target with pvc pipe, would galvanized fair better?
