     3. A water riser that serves a mobile home lot must be equipped with a shutoff valve.

     4. The manager shall take all necessary precautions to prevent the freezing of water supply lines, valves and risers, whether or not the mobile home stand is occupied. The manager shall protect the risers from the heaving and thawing of the ground if the mobile home park is in an area where periodic freezing is encountered. Where ground frosts occur, the shutoff valves must be protected.

     5. Inlets and outlets of fixtures with base attachments which may cause a cross-connection must be protected by a standard nonremovable device for the prevention of backflow or by a standard vacuum breaker that is installed at least 6 inches above the highest point of usage and is located on the discharge side of the last valve.
