Why Backflow Certification Matters

Backflow occurs when water flows in the wrong direction, potentially pulling contaminants like pesticides, fertilizers, or soil into the public water supply. Arizona requires backflow prevention devices on irrigation systems to protect against this risk — and these devices must be tested and certified regularly.

Professional certification ensures:

• Compliance with local and state regulations

• Protection of your property and the community’s water supply

• Early detection of device failures before they cause problems

• Peace of mind knowing your system is safe and approved
