One who has (through experience) acquired a complete understanding of designing
piping systems.
Pipers can be divided into two (2) classes: Contracts and directs. Real
pipers are usually contractors, traveling from job to job seeking the highest current wages. Directs usually hang around after the contractors have left. They fix the mistakes, pick up the pieces, and pull the job together - usually at less wages.
This damn design is all f**
ked up. Must have been one of them
contract pipers.
