Low flow rate (3.2 GPM) at hose bibs severely limits sprinkler irrigation coverage despite adequate static pressure (70 PSI), likely due to undersized piping and fittings.

Homeowner is measuring flow but cannot diagnose the specific bottleneck (meter, PEX size, or hydrant design) without invasive wall opening or professional help.

Workarounds Described

5-gallon bucket fill test to measure flow
trying different hose lengths and diameters

Implied Software Gaps

Automated flow testing and bottleneck identification without manual bucket test

App Concept

FlowPath Diagnoser

A mobile app + hardware kit that measures pressure and flow at multiple points simultaneously, then identifies the exact restriction (undersized pipe, valve, or fixture). Uses color-coded map of plumbing system to show where flow is choked.

Key Features

Simultaneous pressure/flow sensors that attach to hose bibs and main line
Automated plumbing map generation from photos and sensor data
Diagnostic report with specific bottleneck location and recommended fix
Integration with irrigation design to optimize zone sizing

Target Users: Homeowners and DIY enthusiasts with residential irrigation systems, especially those with low flow or uneven coverage

Revenue Model: $89.99 one-time for sensor kit + $4.99 per diagnostic report or $14.99/mo subscription with unlimited diagnostics and personalized recommendations
