A plumber struggles to fit a DWV bathroom setup with proper slope in limited subfloor space while avoiding joists.

No specific software mentioned, but the problem of fitting DWV in tight spaces with proper slope is a design challenge; existing CAD or plumbing design software may be too complex or not tailored for quick, code-compliant layouts in constrained spaces.

It replaces manual sketches and mental math with instant, code-verified plans.

Key Features

Augmented reality (AR) scanning of subfloor dimensions and joist positions
Automatic DWV layout generation with slope calculations per code
Library of standard fittings and pipe sizes for quick drag-and-drop
Exportable diagrams for permits and client approvals

Target Users: Residential plumbers and apprentices in the US who install or repair DWV systems in tight crawl spaces or basements

Revenue Model: Freemium with a $29/mo pro subscription for unlimited projects and code exports
