Plumber needs to diagnose intermittent water leak from shower drain line behind a ceiling with limited access, without clear root cause visible.

Existing diagnostic methods rely on manual visual inspection and trial-and-error; no tool to non-invasively detect intermittent leaks in concealed drain piping.

Implied Software Gaps

Non-invasive diagnostic tool that uses thermal and acoustic sensing to locate drainage leaks through finished ceilings

App Concept

LeakSight Pro

LeakSight Pro is a handheld thermal-acoustic leak detector that plumbers use to pinpoint intermittent water leaks in concealed drain pipes without destructive access. It combines infrared thermography and acoustic sensors to detect temperature and sound signatures of water escaping under use, providing a precise leak location on a smartphone app.

Key Features

Thermal imaging to detect cool spots from evaporating water
Acoustic sensor to capture leak sounds during shower use
Smartphone app overlays leak probability map on wall/ceiling photos
Cloud-based case library to compare with similar leak patterns
Non-invasive, no need to cut multiple access holes

Target Users: Plumbers and maintenance technicians in residential and multifamily building service, especially those handling drainage system diagnostics

Revenue Model: $149/month for device rental and subscription app, or $1,299 one-time purchase with $29/month app access
