WebSelection of pipe size. This water pipe sizing procedure is based on a system of pressure requirements and losses, the sum of which must not exceed the minimum pressure available at the supply source. These pressures are as follows: 3.1. Pressure required at the fixture to produce required flow. See Sections 604.3 and 604.5. 3.2. Web1 is selected with a 42°F entering-water temperature.
