How are the NFPA 13 design requirements . NFPA 13 permits several options for sprinkler piping in all types of systems (16.3), including copper tubing and steel and nonmetallic pipes. Submittals shall include an elevation detail denoting the difference of elevation of the riser from the Water supply capacity is determined through a flow test. For projects in the City of San Diego, a very tall building is a building that is more than 500 feet in building height, as defined by the CBC. Where the combined sprinkler system demand and hose stream allowance of Chapter 12 and Chapters 14 through 20 exceeds the requirements of NFPA 14, this higher demand shall be used. Unlike NFPA 13, NFPA 13R works to make the installation of the sprinkler system more affordable and accessible for residential occupancies by targeting the areas of highest fire risk to life safety with sprinkler systems. The capacity of municipal waterworks, according to NFPA 13 (5.2.2.2), is measured with a fire hydrant flow test and presented as a water supply curve. Where the combined sprinkler system demand and hose stream allowance of Table 11.2.3.1.2 exceeds the requirements of NFPA 14, this higher demand shall be used. NFPA 13:15.2.5 states that water supply connections from penstocks, flumes, rivers, lakes, or reservoirs shall be acceptable, arranged to avoid mud and sediment and shall be provided with approved double removable screens or approved strainers installed in an approved manner.
