A double check valve test form is the record of a test on a double check valve assembly. The 2003 EPA Cross-Connection Control Manual describes that assembly as two checks with test cocks and shutoff valves. The blank you submit is the one your water supplier or local program uses.
What the manual says the hardware is
The manual describes backflow as flow into potable water piping from another source, and backsiphonage as backflow caused by negative pressure in those pipes. It lists double check valve assemblies among the basic means used against backflow and describes them as two checks in one body with test cocks and two shutoff valves, spring loaded, and used in lower hazard settings.

The form
The form is the record page for the assembly you are documenting. It usually captures the device location, the assembly details, the test results, and the tester notes that your water supplier or local program asks for. Backflow Record stores that information for later use.
If you are comparing related device records, the RPZ testing procedure guide can help you see how the format differs. For common questions about records and wording, check the FAQ.
This page is not the test
This page does not perform a test and does not replace the steps in your device manual or local program instructions. The 2003 EPA manual says each check in a double check assembly needs about 1 psi to open, and that criterion belongs to the manual, not to this app.
Use this page only to organize the report you fill in after the test, then submit the blank your water supplier uses. Backflow Record is built to keep that record together in one place.
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.
