QC Plumbing Checklists — Division 22 Overall Quality Controls & Checklist Download

What Division 22 Covers

Plumbing work extends from buried and concealed piping to the fixtures and equipment occupants use every day. Facility water distribution piping must maintain the approved material, joining, restraint, corrosion-protection, and cleanliness requirements from the utility connection through the building service. Facility sanitary sewerage depends on correct inverts, continuous slope, sound joints, stable bedding, accessible cleanouts, and properly installed drainage specialties and pumping equipment.

Supporting sections are just as important. Hangers and supports preserve piping alignment, drainage slope, movement allowances, and insulation integrity. General-duty valves must match the service, pressure, temperature, flow direction, and operating function while remaining accessible after insulation and finishes are installed. Heat tracing introduces electrical cables, controls, sensors, terminations, insulation interfaces, and testing requirements that must be coordinated before concealment.

Equipment and fixture sections complete the system. Commercial gas domestic water heaters require coordinated bases, anchorage, gas trains, venting, relief devices, piping connections, controls, service clearances, and functional testing. Commercial plumbing fixtures depend on accurate rough-ins, secure carriers, accessible valves, backflow protection, tempering devices, drainage connections, finish protection, and final flow and leak testing.

The general plumbing specification context also reinforces division-wide responsibilities for equipment accessibility, identification, testing, flushing, disinfection, operational verification, operation and maintenance data, and personnel instruction. These requirements cross individual section boundaries and are most effective when they are planned and documented as part of one plumbing QAQC program.
