    UNDERSTANDING PRESSURE AND LEAKAGE TESTING Uni-Bell PVC Pipe PE100

    HDPE has a lower modulus of elasticity than all other AWWA pressure-pipe materials. This means that it continues to swell and stretch under test pressures, despite a “conditioning” period for HDPE that is not needed by other materials.

    Also, AWWA permits legacy pipe systems like PVC and Ductile Iron to have allowable leakage the day the are put in the ground. HDPE pipe uses fusion to create a leak-fee joint and AWWA says it is a "leak-free" pipe in C-906-15. Use this leakage calculator to see how much your city is losing each year.
