A plumber cannot diagnose a persistent water sound on the hot side of a shower and lavatory after standard troubleshooting steps, with no obvious leak or cause.

Existing diagnostic tools (cartridge replacement, shutoffs, main shutoff, listening to water heater) failed to identify the source of the sound, indicating a need for advanced diagnostic equipment or methods.

Plumbing diagnostic app with acoustic analysis to identify noise source without manual trial-and-error replacement of parts

App Concept

PipeSound Detective

An acoustic diagnostic tool and app that identifies the source of mysterious water sounds in plumbing systems. It uses vibration sensors and spectral analysis to pinpoint the exact location and cause of noises, even when traditional troubleshooting fails.

Key Features

Vibration sensor that clips onto pipes to detect sound patterns
App with spectral analysis to differentiate normal flow from abnormal noise
Guided diagnostic workflow for step-by-step troubleshooting
Integration with plumbing knowledge base for common noise causes

Target Users: Experienced plumbers and service technicians diagnosing complex residential plumbing noise issues, typically solo or small firms.

Revenue Model: $199 per sensor plus $9.99/mo app subscription for analysis and cloud storage
