PlumbingDiagnostics & Troubleshooting3MediumHomeowner$ implied
Homeowner needs to diagnose and fix toilet drainage issues caused by improper venting in a 1940s house.
Existing AAVs only admit air, but the problem requires expelling air (venting upstream or downstream) to allow drainage; no simple diagnostic tool exists for homeowners to identify correct vent placement.

App Concept
VentWise Pro
A mobile app and sensor kit that helps homeowners and DIY plumbers diagnose toilet drainage issues by detecting airflow and venting needs. It guides users on optimal vent placement and type (AAV vs. roof vent) based on system layout and test results.
Key Features
- Smart P-trap sensor that measures air pressure and flow direction
- Step-by-step diagnostic wizard for identifying venting issues
- AR overlay showing recommended vent locations on house plans
- Digital gas detection for sewage gas (H2S, ammonia) to ensure safe venting
Target Users: Homeowners aged 30-60 with older houses (pre-1980) experiencing toilet drainage issues; DIY plumbers and handymen
Revenue Model: $99 for sensor kit + $9.99/mo subscription for app diagnostics and AR guidance
