A plumbing code requiring vents to be nominally vertical in the attic forces impractical stack placement, complicating drainage design.

Workarounds Described

• places stack locations based on vent termination ease rather than drainage logic
• seeks inspector approval for exceptions

Implied Software Gaps

• Code-aware routing software that optimizes stack placement while ensuring vent compliance
• Digital tool to generate and submit code exception requests to inspectors

CodeNavigator Pro

An interactive code compliance tool that visualizes local plumbing codes and suggests compliant vent routing alternatives. It helps plumbers design optimal drain layouts while automatically flagging code violations and proposing workarounds like alternative fitting configurations or inspector-approved exceptions.
