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 โ no data collection, no ads, no sign-in. 3-day free trial, then $1.99/week. Cancel anytime.

Turn your iPhone into a practical pipe-slope gauge for plumbing, drainage, sewer, and DWV work. PipeGrade helps plumbers, contractors, installers, and DIY users plan runs, measure grade, and keep organized field records. Measure live slope with the motion sensors, calibrate flat and side-edge placements separately, check direction and stability, lock readings, and save them to a pipe run. Calculate slope, fall, horizontal run, or end elevation, then generate station and invert-elevation schedules. Organize projects with notes and field photos, and export field-ready PDF or CSV reports. Supports metric and imperial units, including percent, degrees, in/ft, mm/m, and 1:X. Project data stays on your device unless you choose to export or share it. No account, ads, or subscription. An optional one-time Lifetime Pro purchase unlocks the complete workflow. PipeGrade is a field calculation and documentation aid, not an approval, certification, or substitute for local codes. Verify final work using calibrated equipment and the methods required by your authority and project documents.
