A plumber discovered that both hot and cold supply lines to a shower valve are connected to the same red PEX tube, causing the shower to output only one temperature, and the entire PEX installation is illogical and must be redone.
No existing solution addresses the need for a tool that helps plumbers quickly identify and document cross-connected or incorrectly labeled PEX lines during installation or troubleshooting.
Implied Software Gaps
- A tool that can verify proper hot/cold supply connections without destructive testing
PEXFlow Inspector
PEXFlow Inspector is a mobile app for plumbers that uses a combination of thermal imaging and pressure sensors to map and verify hot and cold supply lines in real-time. It automatically flags cross-connections and generates a color-coded diagram of the plumbing layout, saving hours of manual tracing and rework. Unlike generic thermal cameras, it integrates with job documentation and provides step-by-step correction guidance.
- Real-time thermal and pressure-based line mapping
- Automatic detection of cross-connected hot/cold lines
- Color-coded diagram generation for documentation
- Integration with job management and invoicing software
