In designing a plumbing and drainage system, architects and engineers should bear in mind that adequate pipe space must be provided in order that the system may be installed in an efficient and economical manner. Whether in walls or partitions or beneath floors, sufficient pipe space must be provided to eliminate complicated and undesirable construction and the use of unnecessary fittings which add to the cost of labor and material without increasing efficiency of the system.
