2 GENERAL REGULATIONS This part of the Uniform Plumbing Code is broader in scope, in that it provides the general regulations, instructions, and requirements for the installation and construction of plumbing systems. It requires that sewage or liquid wastes be disposed of by means of plumbing fixtures connected to a drainage system and terminating into a public or private sewer. It prohibits depositing any substance into the drainage system that could cause damage to the system. Additional regulations require that design, construction, and workmanship be in conformity with accepted engineering practices. Included are restrictions prohibiting plumbing systems, or parts thereof, from crossing property lines. The questions in this examination will test you on your knowledge of the aforementioned regulations and also on your understanding of protection of materials and structures, the installation of hangers and supports, and the proper method for trenching, excavating and backfilling. 1.
