Unable to find a replacement ceramic shower stem valve for an old, unlabeled fixture, risking damage to beautiful Italian stonework to access the valve.

Existing solutions (local supply stores, online shopping) lack sufficient dimensions and fit information for obsolete or unmarked parts, forcing trial-and-error and risk of wall damage.

App Concept

ValveMatch Pro

An app that identifies obscure plumbing valve parts using photo recognition, 3D scanning, and a comprehensive database of discontinued and obscure models. Users snap photos of the valve and handle, and the app matches dimensions and notch patterns to the exact replacement part, providing purchase links. No more trial-and-error or wall demolition.

Key Features

AI photo recognition for valve and handle identification
3D measurement tool using phone camera to capture thread size and notch count
Database of current and obsolete valve parts with exact specifications
Direct purchase links to verified suppliers or 3D-printed custom parts

Target Users: Homeowners and DIY plumbers dealing with hard-to-find or unmarked plumbing valve replacements.

Revenue Model: $4.99 per identification, or $14.99/month subscription for unlimited identifications and discounts on purchases.
