  • What is backflow and why is prevention important?

    Backflow occurs when water flows in the reverse direction, potentially allowing contaminants to enter your clean water supply. Backflow prevention devices protect drinking water and help ensure your system meets local safety regulations.

  • How often does a backflow device need to be tested?

    Most municipalities require backflow devices to be tested annually. Regular testing helps ensure the device is functioning properly and keeps your property in compliance with local water authority requirements.

  • Do residential properties need backflow prevention?

    Yes, many residential properties require backflow prevention, especially those with irrigation systems, pools, or secondary water sources. Sanford Water Works can evaluate your system and recommend the appropriate solution.
