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.

  • 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
