Plumbing Fixtures
CSI Division 22, Plumbing
The visible plumbing components a building's occupants actually use, such as sinks, toilets, faucets, and showers, installed near the end of construction once [[concept-rough-in-plumbing|rough-in plumbing]], walls, and flooring are complete, and selected for both function and code compliance (water efficiency ratings, accessible-height requirements).
Why it matters
Accessible fixture requirements, such as mounting height, clearances, and operable controls, are specific, code-mandated dimensions, not general guidelines, and a fixture installed at the wrong height or without adequate clearance can fail an accessibility inspection even if it functions perfectly.
On a real project
A restroom designed for accessibility installs a toilet at the specific height code requires for an accessible stall, with grab bars and clearances positioned to the code's exact dimensions rather than a standard residential layout.
Who this matters most to
A Plumber installs fixtures to the manufacturer's connection requirements and the project's accessibility and plumbing code requirements. A Facilities Manager deals with fixture maintenance, repair, and eventual replacement throughout the building's life, relying on records of exactly what was installed.
Where this goes wrong
A plumber installs a standard-height toilet in a restroom stall designated as an accessible unit, missing that the accessibility code required a different mounting height for that specific stall. The error isn't caught until a final accessibility inspection, requiring the fixture to be removed and reinstalled at the correct height before occupancy can be approved.
