Golden State Water's cross-connection control program in Stanton
Golden State Water Company's West OC system implements a cross-connection control program under California Title 17 that requires annual backflow preventer testing for enrolled service connections in Stanton. The program is administered by Golden State Water's Engineering and Operations department, which identifies connections that present cross-connection hazards, requires appropriate backflow prevention assemblies to be installed and maintained on those connections, and tracks annual testing compliance by reviewing test reports submitted by certified testers on behalf of property owners.
Most Stanton property owners first encounter this requirement when they receive a notice from Golden State Water requesting annual backflow test documentation. The notice identifies the property address, the service connection requiring testing, the device type that must be tested, and the deadline for submitting a passing test report signed by a California-certified backflow prevention assembly tester (BPAT). If you have received such a notice and need to schedule the test, call (855) 575-2890. We hold current BPAT certification and file test reports directly with Golden State Water on behalf of Stanton property owners.
Which Stanton connections require annual testing
The specific connections in Stanton that have been enrolled in Golden State Water's cross-connection control program include commercial and industrial service connections, irrigation system connections (particularly those with chemical injection capability), fire suppression system connections, and some multi-family residential connections above a certain unit count or configuration. The program is specific to the individual connection's hazard assessment rather than a blanket rule by property type, which is why some businesses receive notices while others in similar locations do not.
If your Stanton property has an irrigation system connected to Golden State Water's supply and you have not received a testing notice, it is worth confirming with Golden State Water's cross-connection control department whether your connection has been assessed. New connections (recently installed irrigation systems, fire suppression systems, or commercial service upgrades) are required to be reported to the utility, which then determines whether a backflow preventer is required and initiates the testing program for that connection.
The Stanton annual backflow testing and filing process
When you call to schedule annual backflow testing for a Stanton property, we confirm the device type, location, and accessibility, then schedule the test visit at a time that minimizes disruption to normal water service. The test requires briefly isolating the backflow preventer to connect test gauges, which interrupts flow to the downstream connection for 10 to 20 minutes during the test sequence. For commercial properties with irrigation systems or non-critical connections, scheduling the test outside of peak business hours is preferable but rarely necessary.
After completing the test, we document the results on the required Golden State Water test report form, note any test parameters that approached but did not exceed the failure threshold (which helps predict when the device may need service before the next annual test), sign the form with our BPAT certification, and submit the completed report to Golden State Water within the required filing window. We provide a copy of the filed report to the property owner for their records. The complete documentation includes the test date, device make and model, test results, and tester certification number.
When a Stanton backflow preventer fails the annual test
A device that fails the annual test has an internal component (check valve seat, relief valve diaphragm, O-ring, or check valve spring) that is no longer operating within the performance tolerances required by the device's approval. In most cases, the failed component can be identified by the specific test parameter that produced the failure reading, and the repair is straightforward for common device types. We carry repair kit components for Watts, Febco, Wilkins, and Ames devices in the sizes commonly found in Stanton's commercial and irrigation connections.
For a device where repair is impractical (due to age, discontinued parts, or multiple simultaneous failures), we recommend replacement with a new device of the same type or an equivalent approved model. New device installation requires a permit from the City of Stanton for modifications to the service connection, which we include in the replacement scope and price. After repair or replacement, we retest the device and file the passing test report with Golden State Water before closing out the service call.

Frequently asked questions
Golden State Water sends annual testing notices to Stanton properties with service connections that have been enrolled in the cross-connection control program. These typically include: commercial and industrial service connections; irrigation connections with chemical injection devices; fire suppression system connections; and multi-family connections above a certain unit count. If your property has received a notice from Golden State Water requiring annual backflow testing, the notice will specify the device type, the testing deadline, and how to submit completed test reports.
Golden State Water typically issues annual testing notices with a compliance deadline of 90 days from the notice date for initial compliance or recertification. Properties that miss the deadline receive a follow-up notice before any service interruption action is taken, but the timeline tightens with each successive notice. We recommend scheduling the test within 60 days of receiving the notice to allow time for device repair if the device fails the test on the first attempt.
A device that fails the annual test must be repaired or replaced before a passing test report can be filed with Golden State Water. We repair failed devices on the same visit when parts are available for common device types (Watts, Febco, Wilkins, Ames), or schedule a return visit with the specific parts required. After repair, we retest the device and file the passing report with Golden State Water. Operating a commercial connection with a known failed backflow preventer is a violation of the utility's cross-connection control program and can lead to service interruption.
Annual backflow testing for a single device at a Stanton commercial property runs $75 to $150, including the test, documentation, and Golden State Water report filing. Properties with multiple devices are priced per device at a reduced rate when tested on the same visit. Backflow preventer repair when a device fails the test adds $150 to $400 for standard commercial devices. For property management companies with multiple Stanton properties, we schedule batch testing visits to address all properties within the same compliance window.
