Murrieta Backflow Testing, Installation & Repair

1. Scope & Authority

The water utility serving Murrieta enforces a Cross‑Connection Control and Backflow Prevention Program to protect its potable water system from contamination by backflow or cross‑connections. This program is implemented under the authority of California’s Code of Regulations, Title 17, and local utility or municipal rules. The utility inspects customer premises for potential hazards, mandates the installation of backflow prevention devices where required, and enforces ongoing testing, maintenance, and compliance as a condition of water service. 2. Responsibilities of Property Owners

Installation & Maintenance: Property owners must install and maintain approved backflow prevention assemblies at their service connection or on‑site plumbing locations when cross‑connection hazards are identified by the utility. Devices must be correctly sized, placed so as to remain accessible, and installed in compliance with the utility’s specifications.

Annual Testing: Each backflow prevention device must be tested at least once per year by a certified backflow prevention tester. Tests are also required at installation, after repairs or replacement, or when a device is relocated or modified. Test results must be submitted to the water utility for verification and recordkeeping. Repairs & Replacements: If a backflow prevention assembly fails testing, the property owner is responsible for prompt repair or replacement. After work is performed, the device must be retested and must pass before being placed back into service. 3. Scenarios Requiring Backflow Prevention Assemblies (BPAs) Backflow prevention devices are required wherever there is risk of contamination or cross‑connection. Typical scenarios include irrigation or landscape systems, fire protection / sprinkler systems, swimming pools and spas, properties with auxiliary or alternate water sources, commercial or industrial facilities with processes that may introduce hazardous substances, and temporary service connections (such as construction water lines). The exact type of device (e.g. reduced pressure, double check, vacuum breaker, etc.) depends on the hazard classification determined by the utility.

4. Testing & Maintenance Requirements

Mandatory Testing Events: All installed backflow prevention assemblies must be tested at least once per year by a certified tester. Additional tests are required at the time of installation, after repair or replacement, or if relocated. Certified Testers: Only persons holding valid certification recognized by the utility or regulatory authority may perform backflow testing. They must maintain credentials, use properly calibrated equipment, and follow accepted testing procedures. Submission of Test Reports: Certified testers are required to submit completed test reports in the format required by the utility. Property owners are responsible for ensuring that testing is conducted and reports are submitted on time. Failure to submit reports or conduct required testing may result in enforcement or penalties. Repairs / Replacements: If a device fails testing, it must be repaired or replaced immediately. After repair or replacement, the assembly must be retested and must pass before being placed back into service.

5. Approved Devices & Certified Testers

Approved Devices: Only backflow prevention assemblies meeting recognized design and performance standards may be installed. The required type (for example, reduced pressure principle, double check valve assembly, pressure vacuum breaker, or air gap) must match the hazard level assessed by the utility. Devices should be testable (unless expressly allowed otherwise) and appropriate for their intended application.

Certified Testers: Testing, maintenance, repair, and reporting may only be conducted by individuals with valid certification recognized by the utility or oversight authority. Testers must maintain credentials, use calibrated equipment, comply with approved testing protocols, and are the only permitted parties to submit test reports accepted for compliance. 6. Enforcement & Penalties

Non‑Compliance: Failure by a property owner to install, test, maintain, or properly report on required backflow prevention assemblies constitutes a violation of the cross‑connection control program. The utility may issue notices of violation or require corrective actions. Water Service Interruption & Restoration: The utility may discontinue water service to properties that do not comply with backflow prevention requirements. Service will not be restored until all required devices are correctly installed, tested, repaired (if needed), and documented to the utility’s satisfaction.

Penalties: Additional penalties may apply for late test submissions, failure to act on compliance notices, tampering with or bypassing backflow devices, or repeated non‑compliance. The utility may withhold new service connections, permits, or final inspection approvals until full compliance is achieved under the cross‑connection program.
