CHAPTER 4
FIXTURES, FAUCETS AND FIXTURE FITTINGS

User note:
About this chapter: Plumbing fixtures are required to be installed for nearly every building as toilet facilities (water closets and lavatories) are
needed by the occupants of a building. Additional fixtures for washing, bathing and culinary purposes are also necessary where occupants
dwell in buildings. Chapter 4 specifies the minimum number and type of plumbing fixtures for buildings based on the description of use of the
building. Because fixture design and quality are paramount to ensure that plumbing fixtures operate properly, this chapter also specifies
numerous product and material standards for plumbing fixtures.
