Backflow prevention devices are critical for the health and safety of everyone under your roof. When you need your backflow prevention device repaired or a new one installed, American Plumbing Heating & Air Conditioning can help.

What Is Backflow—and Why Should You Care?

Backflow occurs when water flows in the wrong direction in your plumbing system, pulling contaminants like fertilizers, industrial chemicals, or wastewater into your clean, potable water supply. This can happen due to changes in water pressure from events like a burst pipe or firefighting activities.

That’s why local codes require functioning backflow prevention devices, especially for commercial properties and irrigation systems.

A Properly Functioning Backflow Prevention Device Protects Against:

  • Industrial fluids
  • Gases
  • Used water
  • Pesticides
  • Other hazardous substances

Don’t take chances with your family’s or customers’ health.

Signs You May Need Backflow Repair or Replacement

Not sure if you have an issue? Here are some common warning signs:

  • Water tastes or smells odd
  • Discolored or cloudy water
  • A recent drop in water pressure
  • Your annual backflow test failed
  • You've had recent plumbing issues or flooding

If you notice any of these symptoms, don’t wait. Backflow can lead to serious contamination fast.

    Above & Beyond Service
    "Way overdue in writing this review as it has been quite the year.  However, we are always very happy with the excellent service that we receive from American Plumbing Heating & Air Conditioning that I just need to recognize a company that goes above and beyond.

    This particular review is on Nick and Juan who installed our air conditioner during one of the hottest weeks of the year.  They were so professional and extremely knowledgeable about the unit that was being installed.  From an original visit to installation was seamless and complete in under a week.  They arrived wearing their masks and my home and yard were spotless when they left.  

    I also want to thank the office personnel as scheduling and payment were quick and easy.

    We definitely recommend American Plumbing Heating & Air Conditioning and will continue to do business with them!"

    "I highly recommend American Plumbing Heating and Air. After discovering a leak in our home, I called American Plumbing at 7:00 am on a Friday and spoke with Myra. She was fantastic and dispatched David to come to take a look. He arrived 30 minutes later and within 3 days, David and Ozzie were able to diagnose, repair and repipe our home. They were responsive, on time, and went above and beyond to fix our home. David and Ozzie didn't even break for lunch. Afterward, they did a spectacular job cleaning up and putting everything back they had to move. They even swept the garage! Thank you all so much for taking such good care of us!"
