Purchases and restore

Use Restore Purchases in the app’s Settings if an existing purchase is missing. For a subscription, use Apple’s subscription management instructions. For a refund request, use Apple’s Report a Problem. Purchases and eligibility are tied to the Apple Account used with Apple.

About calculations

Drain, vent and water supply calculations use the tables and assumptions shown in the app. Confirm the selected code edition, local amendments, installation conditions and final design with the authority and a qualified professional.

Common questions

Which plumbing code does PipeFall use?

The app includes IPC based reference tables. Check the edition displayed in the calculation and your local amendments before using a result.

Can it replace a plumber or engineer?

No. It is an estimating and reference aid. A qualified professional must verify the design, installation and local code requirements.

Can I use it without a connection?

Core calculations run on the device. Purchases and restore may require Apple network access.
