Engineering Recommended & Technical Data testing R-26 procedures For HDPE pipe Pressure testing Outside The Trench: If specified by the engineer, pressure testing may be conducted prior to pipe installation. After the pipe has been joined, fill it with water, carefully bleed off any trapped air. Subject the pipe to a hydrostatic test pressure that is times the system design pressure for a maximum of 3 hours. During this time, add water peri- odically to maintain the test pressure; this compensates for the initial stretching of the pipe . The line pressure tightness is determined by visual observation; therefore, it is not necessary to measure the make-up water. Examine every fused joint; any leakage must be repaired and then retested. NOTE: It shall be the responsibility of the contractor to ensure that appropriate safety precautions are observed during hydrostatic testing above ground.
