A DIY homeowner is struggling to properly install plumbing for a garage conversion project, specifically fitting 3-inch pipe with correct slope through floor joists while avoiding ceiling bulkheads.

Workarounds Described

• trying different pipe sizes (4" then 3") through trial and error
• experimenting with different elbow types (long 90 vs standard 90)
• considering sawing through floor to gain height but uncertain about finished floor impact
• posting photos online to get community advice

Implied Software Gaps

• AR measurement tool for joist spaces and clearances before cutting
• Plumbing slope calculator that accounts for fixture types and distances
• 3D visualization of finished floor impact on plumbing installations

PlumbPlan Pro

An augmented reality mobile app that helps DIY homeowners and contractors visualize and plan plumbing installations in existing structures. It uses smartphone cameras to measure joist spaces, calculate optimal pipe routing with proper slope, and generate 3D visualizations showing potential conflicts before cutting begins. It eliminates the trial-and-error approach that leads to wasted materials and structural compromises.
