    Hydrostatic test of polyethylene pipe

    1- Keep in mind that the total hydrostatic test time on a plastic pipe system at a pressure above design pressure should never exceed 8 hours. If there was a piece of piping during which the design would recommend a longer time for it and the time was longer than 8 hours, at the end of the first 8 hours, the test should be stopped and the pressure inside the system should reach zero.
