    Pressure testing of drinking water pipes | Norva24

    Water is pumped into the water pipe to create an operating pressure of 15 bar. The preliminary test, as this is called, lasts for 30 minutes, and is automatically logged by a computer. In this period, the pressure is maintained at a constant of 15 bar, and then a test of the fall in pressure is performed to measure if there is too much air in the pipe.
