Labels you can store
Backflow Record is for naming the device on the record, not choosing it for you. That can help when you are comparing a reduced pressure principle assembly, a double check valve assembly, a pressure vacuum breaker, or a spill resistant pressure vacuum breaker. See the glossary and the double check guide for device names and record terms.
Height note for vacuum breakers
The 2003 EPA manual says a pressure vacuum breaker may be used under constant pressure, does not protect against backpressure, and is installed higher than the outlet it serves. The manual gives that height as at least 6 to 12 inches, and it describes a spill resistant pressure vacuum breaker as a variation meant to reduce spillage with similar installation limits. For more context, see the RPZ guide.
The app does not select hardware
The app stores the backflow test report as a record you fill in. It does not decide which assembly was used, and it does not turn the record into a supplier form. If you want to review the app sections first, visit features. The EPA manual also describes backflow as flow into potable water piping from another source, and backsiphonage as backflow caused by negative pressure in those pipes.
A report in Backflow Record is a record you fill in. It is not a substitute for a licensed tester or for the form your water supplier requires. It does not report an inspection result, and it does not mean a plumbing rule was met.
