Catch errors before construction

AI Plumbing Plan Checker

Cross-reference drainage fixture units (DFUs) against pipe sizing and code requirements. Find riser diagram inconsistencies, fixture schedule mismatches, and piping capacity issues. Results in days, not weeks.

Best for: Plumbing engineers, MEP coordinators, GCs, Plan reviewers.

Why Plumbing Errors Cost So Much

Plumbing drawings define water supply, waste, and vent systems. DFU calculations must match pipe sizing, and code requirements vary by jurisdiction.

Plumbing coordination issues are especially costly because they often require field rerouting that affects multiple trades. Undersized condensate lines cause flooding and equipment damage.

Common issues that lead to costly rework:

  • DFU calculations that don't match pipe sizing
  • Condensate lines undersized for AHU count
  • Riser diagram inconsistencies between floors
  • Fixture schedule mismatches with plan callouts
  • Piping conflicts with structural beams and columns
  • Missing plumbing details and specifications
  • Coordination conflicts with architectural features
  • Code compliance violations (UPC, IPC, local codes)

What the AI Plumbing Checker Catches

AI reviews plumbing drawings to identify issues that manual review might miss—from DFU calculations to condensate line sizing.

DFU & Pipe Sizing Issues
  • DFU counts that exceed pipe capacity
  • Drainage pipe sizing undersized for fixture load
  • Vent pipe sizing inconsistencies
  • Storm drain capacity calculations
  • Cross-reference DFUs against code tables
Condensate & HVAC Coordination
  • Condensate line sizing for multiple AHUs
  • Condensate drain routing conflicts
  • Missing condensate trap details
  • HVAC equipment drainage coordination
  • Condensate pump sizing verification
Riser Diagram Issues
  • Riser diagram inconsistencies between floors
  • Missing riser connections
  • Incorrect pipe sizes in risers
  • Missing riser details
  • Riser-to-plan coordination errors
Fixture Schedule Errors
  • Fixture schedule mismatches with plan callouts
  • Missing fixtures in schedule
  • Incorrect fixture specifications
  • Fixture location conflicts
  • Fixture access requirement gaps
Piping Plan Problems
  • Piping conflicts with structural elements
  • Missing piping details
  • Pipe size inconsistencies
  • Piping routing conflicts
  • Missing pipe supports and hangers
Code Compliance Issues
  • UPC / IPC code violations
  • Florida Building Code plumbing requirements
  • Local plumbing code conflicts
  • Missing code-required fixtures
  • Accessibility plumbing requirements

Real Issues We've Caught

Actual issues found on real projects. Each one would have caused significant rework, change orders, or schedule delays.

Condensate Line UndersizedHigh

What AI Found: Five AHUs connected to single 3/4" condensate line. Code and best practice recommend minimum 1" line for this capacity.

Impact: Prevented condensate backup and potential equipment damage. Would have caused flooding during peak cooling.

DFU Calculation MismatchHigh

What AI Found: Waste line sized for 48 DFUs but fixture schedule totals 67 DFUs on connected branch.

Impact: Caught undersized drain before installation. Would have caused slow drainage and potential backups.

Riser Diagram Floor MismatchMedium

What AI Found: Third floor riser shows 4" waste stack but second floor shows 3" continuing down. Missing transition.

Impact: Prevented field confusion and potential code violation. RFI would have delayed rough-in.
