No easy way for a homeowner to verify a plumber's installation against manufacturer instructions without tearing into walls, and no consumer-friendly diagnostic tool exists to validate diverter valve plumbing connections.

App Concept

PlumbCheck: Install Validator

PlumbCheck is a mobile app that uses computer vision to help homeowners and contractors verify that rough-in plumbing connections match manufacturer specs. Users photograph the exposed valve pipes, and the app overlays the correct inlet/outlet positions per brand, flagging mis-wired connections before walls are closed. It also provides step-by-step guidance with manufacturer videos.

Key Features
  • Snap photo of rough-in valve pipes; AI compares to manufacturer schematics
  • Overlay showing correct inlet/outlet positions per brand (Delta, Moen, Kohler, etc.)
  • Step-by-step video guide for common cartridge and valve installations
  • Report generation showing compliance vs. deviations
Target Users: Homeowners and DIYers doing bathroom renovations, plus small plumbing contractors wanting a self-check tool
Revenue Model: $9.99 per use or $19.99/month subscription for pros with unlimited scans and reporting
