joint type of joint.
PART 39 PVC PIPE LEAKAGE TEST
A. All PVC pipe shall be tested for leakage at 150 psi per AWWA C 605-97, measured at the lowest
point in the line. Any sections of pipelines indicating more than the allowable leakage shall be
repaired and retested until the leakage is less than the allowable indicated below. The leakage test
shall be for a minimum duration of 2 hours. The leakage test shall be made after backfilling. Any
visible leaks shall also be repaired.
