Plumber needs to relocate a shower drain in a mobile home but is constrained by a metal beam and joists, preventing proper pipe routing and vent installation.

Workarounds Described

• asks forum for advice on cutting pipe through joists
• relies on manual measurement and trial-and-error

Implied Software Gaps

• interactive drain routing design that accounts for mobile home metal beams and joists
• code-compliant venting suggestions for tight wall cavities

DrainRite Planner

DrainRite Planner is a mobile app that helps plumbers design drain and vent routing in tight spaces, especially mobile homes. It uses 3D modeling of joists, beams, and walls to suggest optimal pipe paths and fittings, reducing guesswork and rework. Unlike static code books or forum advice, it provides interactive step-by-step guidance for complex retrofits.
