A required submittal element (cut sheet, schedule, calculation, sample) is missing, leaving the package unreviewable as submitted. This guide covers how it shows up specifically in Division 22 Plumbing submittals.

What to look for in Division 22 Plumbing

Commonly required items in Div 22 specs:

  • Plumbing riser diagrams
  • Isometric drawings for waste/vent systems
  • Fixture schedule with rough-in data and GPM/GPF ratings
  • Water heater performance data at design conditions (input, output, recovery, efficiency)
  • Backflow preventer product data and test certification
  • Pipe material and fitting schedule
  • Valve schedule with size, type, and service
  • Insulation schedule for piping
  • Seismic bracing calculations and anchorage details
  • O&M manuals for equipment
  • Warranty documentation
  • Grease interceptor sizing calculations
  • Domestic hot water demand calculations
  • Expansion tank sizing calculations
  • Plumbing fixture spec sheets showing code compliance (ADA, WaterSense)

How severe is it?

Default grade: Fix and Resubmit. The sub completes the package and resubmits before the PM can fully review.

Deviation Check assigns a default per category and escalates or de-escalates based on the spec, always showing its reasoning. See the Division 22 severity rules.

What the PM should do

Stamp the submittal Revise and Resubmit. Mark the deviation, return the relevant spec passage as a redline, and have the sub correct and re-send before fabrication or installation.

Frequently asked questions

What documents are most commonly missing from an incomplete Division 22 Plumbing submittal package?

Fixture schedules with rough-in data and GPM/GPF ratings, water heater performance data at design conditions (input BTU/hr, recovery GPH, thermal efficiency), and backflow preventer product data with test certification are the most frequent omissions. Seismic bracing calculations and anchorage details, grease interceptor sizing calculations, and expansion tank sizing calculations are also commonly absent, leaving the package unreviewable without a resubmittal.

Why can a project manager not fully review a Division 22 Plumbing submittal that is missing the domestic hot water demand calculations or insulation schedule?

Without demand calculations, the reviewer cannot confirm the water heater storage capacity in gallons, recovery rate, or first-hour rating actually serves the design load. Without the insulation schedule, compliance with ASHRAE 90.1 Table 6.8.3 pipe insulation thickness requirements cannot be verified. Both omissions leave core performance questions unanswered. The sub must complete the package and resubmit before the PM can approve, reject, or recommend any action.
