plied with the valve. Lead Free* valves shall be constructed using
Lead Free* materials. Lead Free* Water Detector Shutoff valves
shall comply with state codes and standards, where applicable,
requiring reduced lead content. A water detector pad shall be
installed on the floor beneath the water heater or in a drain pan
supplied by the contractor. The water detector pad shall be
