Polyethylene Water/Sewer - JM Eagle

• The piping system is so designed that it cannot be filled with a liquid.• The piping system service cannot tolerate traces of liquid testing medium.The testing medium should be non-flammable and non-toxic. The test pressureshould not exceed the maximum allowable test pressure for any nonisolatedcomponent in the test section.Leaks may be detected using mild soap solutions (strong detergent solutionsshould be avoided), or other non-deleterious leak detecting fluids applied tothe joint. Bubbles indicate leakage. After leak testing, all soap solutions orleak detecting fluids should be rinsed off the system with clean water.4.10 High-Pressure ProcedureFor continuous pressure rated pipe systems, the pressure in the test sectionshould be gradually increased to not more than one-half of the testpressure, then increased in small increments until the required test pressureis reached. Test pressure should be maintained for 10 to 60 minutes, thenreduced to the design pressure rating, and maintained for such time as requiredto examine the system for leaks.4.11 Low-Pressure ProcedureFor components rated for low pressure service the specified rated test pressureshould be maintained for 10 minutes to one hour, but not more than onehour. Test pressure ratings must not be exceeded. Leakage inspectionsmay be performed during this time. If the test pressure remains steady(within 5 percent of the target value) for the one-hour test time, no leakageis indicated. Pressure testing of gravity-flow sewer lines should be conductedin accordance with ASTM F1417, Standard Test Method for InstallationAcceptance of Plastic Gravity Sewer Lines Using Low-Pressure Air.HDPE WATER/SEWER PIPING SYSTEM TECHNICAL & INSTALLATION GUIDE21
