Backflow prevention systems play a critical role in protecting clean drinking water from contamination caused by reverse water flow. At Craig Fire Protection, we provide professional backflow prevention testing, inspection, installation, repair, and certification services for commercial, industrial, and residential properties throughout Arizona. Our certified technicians help ensure your water systems remain safe, compliant, and operating properly according to local and national regulations.
What Is Backflow Prevention?
Backflow occurs when water flows in the opposite direction within a plumbing or fire protection system, potentially allowing contaminated water, chemicals, debris, or stagnant water to enter the clean water supply. Backflow prevention devices are specifically designed to stop this reverse flow and protect potable water systems from contamination.
Backflow prevention assemblies are commonly installed on fire sprinkler systems, irrigation systems, commercial plumbing systems, and industrial water lines. These devices require regular testing and maintenance to ensure they function properly and comply with safety regulations.
At Craig Fire Protection, our team services a wide range of backflow prevention devices, including:
- Reduced Pressure Zone (RPZ) assemblies
- Double Check Valve Assemblies (DCVA)
- Pressure Vacuum Breakers (PVB)
- Fire line backflow preventers
- Domestic and irrigation backflow assemblies
Who Needs Backflow Prevention Services?
Backflow prevention services are required for many commercial, industrial, and residential properties throughout Arizona. Any property connected to a fire sprinkler system, irrigation system, chemical processing equipment, or commercial plumbing system may be required to install and maintain certified backflow prevention devices.
Properties that commonly require backflow prevention include:
- Commercial buildings
- Restaurants and food service facilities

In Arizona, local municipalities and water authorities often require annual testing and certification of backflow prevention devices to help protect public water systems from contamination.
Backflow Prevention Code Requirements
Backflow prevention systems must comply with national fire protection and plumbing standards as well as Arizona and local municipal regulations. Depending on the property type and fire protection system, multiple NFPA standards may apply.
Relevant standards include:
- National Fire Protection Association NFPA 13 – Installation of Sprinkler Systems for commercial and industrial properties
- NFPA 13R – Fire sprinkler systems for low-rise residential occupancies
- NFPA 13D – Fire sprinkler systems for one- and two-family homes
- NFPA 25 – Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems
- Local Arizona plumbing and cross-connection control requirements
Many municipalities in Arizona require annual certified testing of backflow prevention assemblies, documentation of inspections, and compliance reporting to local water authorities. Fire line backflow systems connected to sprinkler systems must also meet additional inspection and testing requirements.
Our experienced technicians stay current with Arizona code requirements and NFPA standards to help ensure your property remains compliant and protected.
