Plumbing, Electrical, or other field serviceDiagnostics & Troubleshooting4HighPlumber$ explicit

A plumber with residential experience cannot identify and fix persistent water hammer in hot water lines, despite multiple interventions.

Existing solutions (arrestors, pressure valves) are generic and don't diagnose or locate the root cause (likely unsupported pipes in walls) without destructive wall cutting.

Workarounds Described

Opens and closes taps rapidly while wife listens for vibrations in roof space and subfloor
Drains entire system to temporarily eliminate water hammer for about a week
Replaces multiple components (tap washers, flickmixer, ministops, duo-valve, pressure valve, arrestors) by trial and error

Implied Software Gaps

A mobile diagnostic tool that uses sensor data to map pipe vibration and suggest precise fix locations

App Concept

HammerLocate Pro

A mobile app paired with a vibration sensor that plumbers can temporarily attach to pipes to systematically locate the source of water hammer without cutting walls. The app guides step-by-step diagnostics, logs test results, and suggests targeted fixes, saving hours of guesswork and drywall repair.

Key Features

Vibration sensor with magnetic clip for temporary pipe attachment
App guides user through valve closure tests and records vibration signatures
Heatmap overlay on house blueprint to pinpoint unstable pipe locations
Drain-down timer and air-bleed suggestion based on system age

Target Users: Residential and commercial plumbers diagnosing water hammer issues in single-family homes and small apartment buildings

Revenue Model: $49 one-time sensor + $19/mo app subscription, or $199 full kit with 3 sensors and lifetime app access
