When sizing the water distribution system for a building, which CPC-recognized method bases pipe sizes on total demand expressed in water supply fixture units and available pressure?
a.Counting only the number of rooms
b.Matching the sewer pipe size
c.The fixture-unit sizing method using the code's sizing tables
d.Using the same size as the gas piping
Explanation
CPC 610.0 sizes water piping using water supply fixture units (WSFU), developed length, and available pressure applied to the code's sizing tables. This translates fixture demand into required pipe diameters. Choosing the correct sizing method on the plan ensures adequate flow without oversizing.
