It is the responsibility of the water customer to ensure that the backflow prevention assembly is in proper operating condition at all times. Backflow prevention assemblies must be tested annually. The City of Healdsburg sends notices to customers reminding them when the annual test is due.
The customer must contact a City of Healdsburg recognized tester to perform the test. If any repair work (including repairs resulting from freeze damage) or maintenance is performed on the assembly, a city recognized tester must re-test the assembly immediately and submit the test results to the City.
