Auto Pipe Routing & IPC Sizing

Based on fixture unit counts, the system routes supply and DWV pipes with correct slopes (1/4" per foot for drains) and pipe diameters according to IPC/UPC code tables. It also checks for conflicts between supply and drain lines during layout.

  • Drain slope and pipe diameter based on IPC tables
  • DWV routing with vent stack and cleanout placement
  • Supply line sizing by fixture unit demand

Use Cases

Plumbing Plan Examples & Use Cases

From whole-home rough-ins to focused bathroom remodels — here are common plumbing plan layouts.

Residential plumbing plan example

Residential Plumbing Plan

Whole-house water supply and drainage layout. Map hot and cold water lines to every fixture, size pipes by fixture unit count, and route vents through the roof on a single residential plumbing plan.

Bathroom and kitchen plumbing plan example

Bathroom & Kitchen Plumbing

Detailed wet-area layouts with sink, toilet, shower, tub, and appliance connections. Include trap arms, vent risers, and stub-out locations for accurate rough-in coordination.

Drain waste vent system plan example

Drain-Waste-Vent System Plan

Drain-Waste-Vent isometric and floor plan views showing pipe slopes, cleanout locations, vent stack routing, and main drain connections. This layout is commonly required for permit review in many jurisdictions.

Water supply plan example

Water Supply Plan

Hot and cold water distribution from the main line to every fixture. Size supply pipes by fixture unit demand, plan manifold locations for PEX systems, and specify water heater connections.

Radiant floor heating plumbing plan example

Radiant Floor Heating

PEX tubing loop layouts with manifold locations, supply and return headers, and zone valve wiring. Calculate loop lengths, spacing, and flow rates for even heat distribution across each room.

Plumbing riser diagram example

Plumbing Riser Diagram

Multi-story vertical pipe routing showing stack connections, fixture branches, and vent terminations. Coordinate between floors with elevation callouts, pipe material specifications, and vertical connection details.

Simple Process
