Tired of flipping through code books on the job just to size a drain? PipeFall turns fixture counts and pipe runs into code-referenced sizes in seconds. Here's how it works: pick your code, add your fixtures or enter your run, and PipeFall returns the minimum pipe size, the required slope, and a pass-or-fail check against the exact table it used. Done. No accounts. No uploads. No tracking. Everything happens on your iPhone. Whether you're roughing in a bathroom, sizing a building drain, or checking a trap arm before the inspector arrives, PipeFall is built to be the fastest way to get the number right the first time. It covers drainage fixture unit sizing, water supply sizing with Hunter's curve, drainage slope and fall in every common format, vent and trap arm checks, pipe offsets and rolling offsets, pipe volume and weight, and thermal expansion. Every table is based on the 2021 International Plumbing Code, so the sizes match what the inspector checks against. You can even set your iPhone on the pipe and use it as a slope level, then send the reading straight into the calculator. Every result is referenced to the code table behind it, so you can always show your work. Save jobs, group your calculations, and export a clean PDF for the file or the client. PipeFall runs 100% offline — no data collection, no ads, no sign-in. 3-day free trial, then $1.99/week. Cancel anytime.
