What to check for Buckeye
Buckeye explicitly carves out engineered fire lines as the place where a double check assembly is used instead of the default RP.
- Due basis: Buckeye says the city sends annual test due notices to backflow assembly users and requires annual testing at hazardous cross-connections under city code and ADEQ rules.
- Notice or device clue: Look for the utility name, service address, assembly serial number, account or notice ID, and due date.
- Who is affected: Buckeye customers with hazardous cross-connections, including multifamily, commercial, industrial, dedicated irrigation, and engineered fire-line services.
- Acceptance rule: Use the listed submission method and keep proof that the report was filed with the utility.
