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
- Gasses
- 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.- Tracy B.
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!" -
“The repairmen were prompt, professional and did a thorough check of possible areas that might be affecting the heating system.”- Kathy T.
Very Happy
"The heater in my home was working sporadically, so I contacted APH&AC. They were exceptionally courteous and fit me in their busy schedule for the same day. The repairmen were prompt, professional and did a thorough check of possible areas that might be affecting the heating system. They spent about 90 minutes (which far exceeded just the typical "here's the problem, here's your bill"). Once the issue was detected, they let me know the anticipated cost of the part and what the results would be. I was very happy with their work, professionalism, and courtesies and highly recommend this company."- Kathy T. -
“Andrew was amazing and was able to repair our A/C unit very quickly and efficiently.”- Nichol H.
Highly Recommend
"Andrew was amazing and was able to repair our A/C unit very quickly and efficiently. He was able to come within one hour of me calling in on a Saturday! Once he removed the A/C box, we were surprised with 3 fried rats!! He was able to remove them and fix our A/C. It's working great! We would highly recommend this company and Andrew!"- Nichol H. -
“I will be using American Plumbing for all my plumbing and air conditioning needs in the future.”- Rick E.
Friendly Attitude
"I had a tenant who needed immediate attention the evening before Thanksgiving. American Plumbing immediately dispatched a plumber who had gone home to relax on a wet and cold evening. David cheerfully set aside his evening meal to solve my problem. The job was done efficiently, with a friendly attitude, and at a fair price. Having used dozens of plumbers during more than 40 in north county, I will be using American Plumbing for all my plumbing and air conditioning needs in the future."- Rick E. -
“American Plumbing will be our new HVAC agency in the future, and I would recommend Nicholas to anyone!”- Patty S.
What a Relief!
"After 5 days of waiting on another HVAC company who was "waiting on the manual from the manufacturer" to even begin to diagnose what was wrong with our A/C unit, we called American Plumbing. What a relief! Nicholas C came out right away and within minutes showed us that one of the circuit boards had burn marks that indicated an obvious issue. He ordered the parts the same day, had them express shipped, and showed up within a day of receiving the parts to get us up and running again. Nicholas was friendly, professional, honest, and efficient. American Plumbing will be our new HVAC agency in the future, and I would recommend Nicholas to anyone! He helped us get back to full business. Thank you!!"- Patty S.
