Sec. 19. (a) A deflection test must be performed on each flexible pipe following the elapse of thirty (30) days after the placement of the final backfill.

(b) The pipe must not exceed a deflection of five percent (5%) or greater.

(c) The diameter of the rigid ball or mandrel used for a deflection test must be no less than ninety-five percent (95%) of the base inside diameter of the pipe to be tested, dependent on what is specified in the corresponding ASTM standard. The test must not be performed with the aid of a mechanical pulling device.

(d) All gravity sewer pipe must be tested using one (1) of the following leakage test types:

1. (1) A hydrostatic test must be performed with a minimum of two (2) feet of positive head. The rate of exfiltration or infiltration must not exceed two hundred (200) gallons per inch of pipe diameter per linear mile per day.

2. (2) An air test must conform to one (1) of the following methods:

   1. (A) ASTM C828-90*, Standard Test Method for Low-Pressure Air Test of Vitrified Clay Pipe Lines, for clay pipe.
   2. (B) ASTM C 924-89*, Standard Practice for Testing Concrete Pipe Sewer Lines by Low-Pressure Air Test Method, for concrete pipe.
   3. (C) ASTM F1417-92*, Standard Test Method for Installation Acceptance of Plastic Gravity Sewer Lines Using Low-Pressure Air, for plastic pipe.

(e) All force mains must be pressure and leak tested in accordance with one (1) of the following methods:

1. (1) AWWA standard C600-93**, AWWA Standard for Installation of Ductile-Iron Water Mains and Their Appurtenances.
2. (2) AWWA standard C602-89**, AWWA Standard for Cement-Mortar Lining of Water Pipelines-4 In. (100 mm) and Larger-In Place.
3. (3) AWWA standard C603-90**, AWWA Standard for Installation of Asbestos–Cement Pressure Pipe.
4. (4) AWWA standard C605-94**, AWWA Standard for Underground Installation of Polyvinyl Chloride (PVC) Pressure Pipe and Fittings for Water.
5. (5) AWWA standard C606-87**, AWWA Standard for Grooved and Shouldered Joints.

If an AWWA standard is not available for the particular installation, the installation procedure recommended by the manufacturer must be followed.
