    The main water line pipe is what brings water from your local utility company into your home. In most cases, a homeowner won't be accessing these pipes themselves. However, main water line pipes need to be installed below the frost point for their geographical region so they won't freeze in the winter. Since frost points can vary, homeowners should call their local building officials to discover the building codes for their region.

    On the Other: Sprinkler Pipes

    Sprinkler systems are normally run using PVC pipes, which can freeze and crack in the winter if they are not drained properly. Even still, they are not required to be installed below the frost point. It is recommended that sprinkler pipes be installed at least 8 inches below the surface to prevent accidental breakage.

    Bottom Line

    Since the main lines are already installed whenever a home is purchased, the only outside water lines most homeowners have to worry about are the ones used for their sprinkler systems. If the homeowner installs their sprinkler water lines at least 8 inches below the surface, and they drain the pipes before the first frost hits, the pipes will withstand the winter and remain in good shape come spring. Also, it is important to remember to call 811 (Call Before You Dig) prior to digging so you can have your utilities flagged out on your property.
