How are annual backflow test reports submitted to the City of Phoenix in 2026?
Unlike suburbs that charge third-party portal fees, the City of Phoenix accepts original, signed City of Phoenix Backflow Prevention Assembly Test Reports directly by email at [email protected] (or by mail to 438 W.

The test must be performed by a company on the active City of Phoenix Approved Backflow Tester Company List using a gauge calibrated within the last 12 months, and customers must keep copies of test records for at least 3 years.
What happens if I miss my City of Phoenix backflow test due date?
Under Phoenix City Code Chapter 37, Section 37-146, failure to test, repair, or submit records for a required backflow assembly can result in termination of water service after 10 days written notice (or immediate termination without prior notice if the Water Services Director determines a public health hazard exists). In addition, the City may impose a civil penalty of up to 1,000% (10x) per billing period on all water charges from the date corrective action was required until compliance is achieved.

Under Phoenix City Code Chapter 28 (Sections 28-12 through 28-15) and the Water Services Department Environmental Services Division (ESD) FOG BMP Manual, indoor hydromechanical grease traps (permitted for up to 4 fixtures with no dishwasher or disposal) must be completely pumped and cleaned every 30 days and never exceed 90 days.
