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.
