HDPE may be used for water service pipe only up to the water meter. Particular care shall be taken to avoid sharp edges in contact with the pipe and provide for expansion and contraction. All service connections larger than 2” (two inches) are required to be pressure tested at 150 lbs (one hundred fifty pounds) psi for 1 (one) hour with no loss of pressure. AWWA approved Polyethylene (PE) B72.1 – D2239 material is required for water services. All fire protection lines shall have detector check valves.

  6. Where pressure reducers are required, the pressure reducer (supplied by plumber) will be located on the house side of the meter and before the second valve. Meters will be marked with pressure reducer notation.
  7. Connection, access, and meter fees must be paid, and a copy of the plumbing permit supplied, before delivery of the water meter will be made.
