App Concept
PlumbCheck Recirculation Advisor
A mobile app that helps homeowners and plumbers design and verify correct hot water recirculation plumbing configurations for multi-tank systems. Users input their tank setup (number, series/parallel, pipe runs) and get a diagram and checklist ensuring code-compliant, efficient routing.
Key Features
- Interactive plumbing diagram builder for up to 4 tanks
- Step-by-step installation checklist based on input configuration
- Automatic detection of common mistakes (e.g., return line placed between tanks instead of before first tank)
- Integration with local plumbing code databases
Target Users: Homeowners and plumbers in residential settings with multiple water heaters, particularly those retrofitting or replacing aging systems.
Revenue Model: Freemium with $4.99 one-time fee per diagram; pro subscription $9.99/month for unlimited diagrams and code updates.
