Facility Piping Systems Handbook, Second Edition

This chapter describes various interior plumbing systems and provides the system design criteria necessary for accurate and cost-effective sizing of equipment and piping for each of the systems. For a continuation of some of these systems outside of a building on the site, refer to Chap. 6, Site Utility Systems, for potable water supply, sanitary drainage, and storm water disposal.
Plumbing systems directly affect the health and safety of the public, and thus are distinguished from other piping systems by the following general requirements:
The design, materials, and installation of the systems are directly regulated by a plumbing code.
System design must be approved by an authorized code official charged with the responsibility of ensuring plumbing code compliance.
A permit for installation of the systems must be obtained from the authority having jurisdiction.
The systems shall be installed by an individual duly licensed by the authority having jurisdiction for determining the competence of an individual to obtain a plumbing installation license. This may not be required in some jurisdictions.
The installed systems must be inspected and approved by an authorized code official charged with the responsibility of code enforcement.
The basic plumbing systems are
Sanitary drainage
Sanitary vent
Storm water drainage
Potable water
Fuel gas (Refer to Chap. 13.)
Plumbing codes establish minimum acceptable standards for the design and installation of the various plumbing systems and for the components that compose them. There are six regional building codes that, along with their associated plumbing codes, have...
