Discover our Certified Backflow Prevention Services

Clean water is essential to your home or business — and keeping it protected is just as important. At Albano Contracting, we provide professional backflow prevention, testing, and repair services throughout Nassau and Suffolk County. With over 24 years of experience and proper licensing, our team ensures your water supply stays safe, compliant, and free from contamination risks.


If you're a homeowner, property manager, or business owner, it's your responsibility to prevent cross-contamination between your plumbing system and the public water supply. That’s where backflow prevention comes in.

What Is Backflow — and Why It Matters

Backflow occurs when contaminated water reverses direction and flows back into the clean water supply. This can happen due to pressure changes in your plumbing system — often caused by burst pipes, heavy water use, or equipment malfunctions.


Without a working backflow prevention device, pollutants like chemicals, fertilizers, and waste could enter your drinking water. This poses serious health risks to your family, employees, or customers — and can also result in fines or utility service interruptions if you’re not in compliance.

Backflow Repair and Maintenance

If your device fails inspection, we’ll troubleshoot and repair it quickly — restoring functionality and helping you pass retesting with minimal disruption.

Compliance Reporting

We provide the documentation needed to stay compliant with your town, village, or water district requirements. We take care of all the paperwork so you don’t have to.

Who Needs Backflow Prevention?

Backflow prevention isn’t just for large commercial buildings. Local regulations require it in many residential and small business settings, especially if your property has:

  • Irrigation or sprinkler systems

  • Pools or spas

  • Fire suppression systems

  • Boilers or heating systems connected to potable water

  • Commercial kitchens or food prep areas

  • Industrial or chemical operations

If you're unsure whether your property needs a device or inspection, we’ll be happy to review your setup and advise you.

FAQs About Backflow Prevention

  • What is a backflow prevention device?

     It’s a mechanical valve system that keeps contaminated water from flowing back into the clean water supply. It's typically installed where your plumbing connects to the public water main.


  • How often is testing required?

     New York regulations require annual backflow testing by a certified professional. We also recommend additional checks after major plumbing work.


  • What happens if I don’t test or repair my device?

    You could face fines or have your water service shut off until you're in compliance. More importantly, your drinking water could be at risk.


  • Can you submit the test results to the water authority?

    Yes. We file all necessary paperwork and certification forms on your behalf.
