NOT marking the vertical tolerance of a water line caused an accidental hit which, in turn, caused a resident's basement to flood.  This is a common because the VERTICAL TOLERANCE is not marked.  A Utility Depth Marker provides the exact measurement of the vertical tolerance and prevents this type of damage.
