Sizing water supply lines

The link below has information on pipe sizing for water to residential homes. For more information, you should pick up a plumbing code book that applies to your location. This link has the average situation that most people would encounter. Keep in mind that differences in length of pipe, lower pressures and local plumbing code does make a difference. Engineered systems with manifold and PEX piping would have altogether different sizing.
