   The following rules shall be strictly adhered to by all persons performing any plumbing work in or upon any of the water mains, connections or appliances pertaining to the district, and any violation thereof or failure to comply therewith or to comply with the other ordinances and regulations of the district shall be considered a violation and breach of the condition of the plumber’s bond required in Chapter 50.
   (A)   Rule 1: backflow preventer. A backflow preventer shall be placed on all service lines prior to the meter.
   (B)   Rule 2: pipes to be blown out. Plumbers must first blow out the pipes before setting any meter, and the meter must in all cases be set without the use of red lead or any other substance for packing in the fittings and must be set level and made firm by resting on proper support.
   (C)   Rule 3: test and inspection of water pipes. No water pipes laid underground shall be covered and the trenches filed up by any plumber until after the water has entered into such pipes under pressure and the same pipes shall have been tested and found to be watertight, and said pipes and connections shall be tested and inspected by the district during normal working hours. The plumber shall give the district 48 hours’ notice prior to testing of the water pipes.
   (D)   Rule 4: water shut off by the district. In no case shall the plumber operate valves, whether they be curb valves or street valves, for any purpose.

In addition to the district’s remedies under the plumber’s bond as set forth in Chapter 50, the district shall have the authority to suspend the right of any plumber to make connections to district property for non-compliance with these rules and regulations. Such suspension shall take effect immediately and shall remain in effect until the alleged violation and suspension can be reviewed by the Board of Supervisors.
   (H)   Rule 8: review. The district shall review, and the Board of Supervisors shall approve, the plans and specifications of all extensions of the district water system.
