New 2025 Backflow Prevention Regulations Are Changing How Sacramento Homeowners Protect Their Water Supply
Sacramento homeowners are facing significant changes in backflow prevention requirements as California implements stricter water safety regulations throughout 2025. These new rules, designed to protect municipal water supplies from contamination, affect both residential and commercial properties across the region.
Understanding California’s New 2025 Backflow Prevention Standards
California’s Cross-Connection Control Policy Handbook (CCCPH) has introduced significant changes to backflow testing requirements that took effect July 1, 2024, with additional provisions coming into force in 2025. Beginning July 1, 2025, California mandates that all backflow assembly testers and cross-connection control specialists be certified through a program recognized by the State Water Resources Control Board (SWRCB). By July 1, 2027, those certification programs must also be ANSI-accredited, ensuring a standardized level of competency and regulatory compliance statewide.
What makes these regulations particularly important for Sacramento homeowners is that backflow testing is no longer a routine task, it’s now a regulated requirement with stricter oversight across California. This shift represents a fundamental change in how water safety is managed at the residential level.
What Sacramento Homeowners Need to Know
While single-family residences are not generally required to have a backflow device, there are specific situations where Sacramento homeowners must comply with the new regulations:
- ADU Construction: Backflow prevention devices are now non-negotiable for ADUs. These protect the municipal water supply from contamination. Expect requirements for backflow devices on irrigation lines, potable water supplies, and where sewer connections are shared with the main house.
- Secondary Water Sources: All secondary sources of water, such as wells or plumbing systems that are exposed to potential contamination or poorer quality water, require an above ground backflow prevention device.
- Irrigation Systems: Properties with irrigation systems may require backflow prevention, especially if they connect to the municipal water supply.
- Fire Sprinkler Systems: For residential property, it is important for owners to alert CCWD if any changes are made, such as digging a new well or adding a fire sprinkler system.
New Installation and Testing Requirements
The 2025 regulations bring several key changes that homeowners must understand:
Above-Ground Installation Mandate
As of July 1, 2024, all commercial below ground backflow devices will be required to be replaced with above grade devices whenever there is a change in ownership, change in use or modification made to the building, in compliance with new regulations enacted by the State of California. Additionally, all new or replacement residential backflow devices are required to be installed above ground.
Certified Testing Requirements
Only certified Backflow Prevention Assembly Testers can perform these tests. Starting July 1, 2025, testers must hold certification from a California-recognized organization to comply with updated regulations. Backflow devices are required to be tested annually from the date of installation, or any time the device has been repaired, replaced, or relocated. This annual test is the responsibility of the customer.
Documentation and Reporting
Proper documentation is crucial for compliance. Test results must be submitted to the water provider within 10 days of testing using their approved format. Beyond test results, California regulations require documentation of system surveys, hazard assessments, and device installations. All records must be available for inspection by water system representatives or regulatory agencies upon request.
Cost Implications for Sacramento Homeowners
The new regulations come with financial considerations that homeowners should plan for. Backflow prevention devices are supplied and installed by CCWD and paid for by the customer. Additionally, the installation of the double check valve will reduce your pressure by approximately 6-9 pounds per square inch and the reduced pressure device will reduce your pressure by 9-14 pounds per square inch. Either device will also reduce your water flow due to the reduced pressure.
Simple Prevention Steps for All Homeowners
Even if your property doesn’t require a formal backflow prevention device, homeowners occasionally install washing or chemical feeding equipment (such as a plant fertilizer sprayer) on hose bibs. This equipment can create backflow that could contaminate both the home’s water supply and the public supply. Installing hose bib vacuum breakers on all hose bibs is an easy and inexpensive way to prevent harmful contamination.
