Backflow testing for Tucson homes
Most irrigation systems here have a pressure vacuum breaker (PVB) or reduced pressure (RP) assembly where the sprinkler line leaves the house. Because they sit outside, they're vulnerable to freezing and are commonly damaged when a system isn't blown out before winter.
For the full guide, including what you can safely do before a plumber arrives, see backflow testing explained.

Local conditions
Backflow testing in Tucson: what's different
Tucson Water requires testing of backflow devices on irrigation systems. Devices can crack on rare cold nights when exposed.
A certified tester checks each valve and reports results to the utility.
Many Tucson homes use drip irrigation and rainwater harvesting, which have backflow devices that must be protected from contamination and freezing. A device that fails its test usually needs new seals or springs; one cracked by a cold night is replaced. Monsoon season is also a good time to check irrigation lines and yard drainage.
