Mainline, lateral, and wiring are routed within the same trench with a minimum two-inch clearance maintained between pipes. Solvent weld plastic piping is snaked within the trench to allow for thermal movement. Wire is run beneath and beside the mainline, taped, and bundled at ten-foot intervals. A twenty-four-inch loop is tied in all wiring at changes of direction of thirty degrees or greater, and untied after all connections are made. Sleeving below all hardscape elements utilizes Class 200 PVC twice the diameter of the enclosed pipe or wire bundle.
