Homeowner needs to fix a slow-flushing toilet caused by improper pipe slope in a confined crawlspace, but cannot easily re-plumb due to space constraints and existing pipe obstructions.

PipeSlope Solver

An augmented reality (AR) app that lets a DIYer visualize and plan toilet drain re-piping in confined spaces. The app uses phone camera to scan joists and existing pipes, suggests optimal slope paths, and generates a 3D cut list with step-by-step instructions. It replaces trial-and-error hacking with precise, constraint-aware design.
