The more I think about the design of plumbing systems the more I realize I don't fully understand it.
For your answer I'd think you have to look in one of those fat, thick, little handbooks for residential or commercial plumbing design that Border's used to have. Barnes & Noble doesn't seem to be as good on this count.
For HVAC there's ASHRAE. Maybe there is a similar org. for plumbing design/engineering.
