Cannot stop a Toto wall-hung toilet from constantly dripping after replacing the main plunger/flapper and seal.

Lack of accessible, model-specific diagnostic guides for concealed-tank toilets, forcing users to rely on general plumbing knowledge.

App Concept

ConcealedToilet Fix

A diagnostic app that guides users step-by-step through troubleshooting Toto wall-hung toilets and other concealed-tank models. Uses model-specific diagrams, common failure patterns, and replacement part identification to eliminate guesswork.

Key Features

Model-specific diagnostic flowcharts
Visual guides with exploded diagrams for concealed tanks
Parts identification scanner using phone camera
Video tutorials for common repairs

Target Users: Homeowners and DIY enthusiasts with Toto wall-hung toilets (or other concealed-tank models) who lack specialized plumbing knowledge

Revenue Model: $2.99 per diagnostic guide download or $9.99 annual subscription for unlimited access to all model guides

Part of App Idea

High-end TOTO toilets are unreliable due to frequent clogs and broken slow-close seats, and proprietary parts make repairs difficult and expensive.
