PlumbCheck: Install Validator

PlumbCheck is a mobile app that uses computer vision to help homeowners and contractors verify that rough-in plumbing connections match manufacturer specs. Users photograph the exposed valve pipes, and the app overlays the correct inlet/outlet positions per brand, flagging mis-wired connections before walls are closed. It also provides step-by-step guidance with manufacturer videos.
