Hydrostatic testing of ductile iron pipe shall conform to AWWA Standard
C-600, Section 13 and AWWA Standard C-603, Section 19, respectively.
The pressure test shall be performed by increasing the hydrostatic

period of one hour. Any pipe, fittings, or valves found defective
shall be replaced. Prior to performing the test, all air pockets and
bubbles must be eliminated. Hydrostatic test pressure shall be 250
PSI for ductile iron pipe.
