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.

-
“He ended up recommending equipment that is much stronger, more efficient (DC vs AC), and it is seamlessly integrated with the rest of our smart home.”- Thomas B.
Quick and Honest Work
"My wife had started the process of getting bids for a new AC system on the house. The bids she was getting were pure insanity. We had American Plumbing out to do our tankless water heater, and I knew they did AC. I also had Nick from American out earlier to our house to replace a capacitor on our old failing system, and he was quick and honest about the job. I wanted to hear his take on our job. He ended up recommending equipment that is much stronger, more efficient (DC vs AC), and it is seamlessly integrated with the rest of our smart home. All for about $8k less than the other bids we were getting. I even got a roll-around AC unit for my garage/shop as part of the deal.- Thomas B.
Side bonus. My hummingbirds no longer fly away the second the AC fires up." -
“Took less than an hour!”- Jeannette L.
Very Nice and Professional
"After contacting three other plumbers and getting elusive responses, I contacted American Plumbing and had a Technician out the next day. The kitchen sink had been clogged several days after Thanksgiving, as well as a shower drain. Took less than an hour! David was very nice and professional."- Jeannette L. -
“You have two very wonderful men in your employment.”- Pat & Tom
Andrew and Reuben are wonderful!
"We want to thank Andrew and Ruben for coming here to repair our backflow device. We got a letter threatening to discontinue our service if we did not have it fixed in 30 days, and your team was able to fix it in 5! It means so much to us to have this matter resolved properly, you have two very wonderful men in your employment. Thank you for all you did to help us last week!"- Pat & Tom -
“It was a pleasure to watch them solve the problem. They were quick, neat, funny, and kind, and patient with my father's chit-chat.”- Rosalinda R.
Highly Recommended
"Keep it in the family. My sister has used their services; she highly recommended them. They did not disappoint.- Rosalinda R.
As a business etiquette consultant, I teach customer service, so I'm always aware of phone manners, courtesy, and communication.
When I called, Myra, answered the phone. Her tone of voice was so welcoming and cheerful. She listened and understood the urgency my 93-year-old father had to address the leaky sink. I didn't feel like just "another call". Thank you, Myra!
And then, David and Ozzy showed up. It is so nice to see people who enjoy their profession and have a happy disposition. They both seem to complement each other, exchanging thoughts and solutions, with enthusiasm. It was a pleasure to watch them solve the problem. They were quick, neat, funny, and kind, and patient with my father's chit-chat.
I already told a neighbor about them. Thanks, Myra, David, and Ozzy!" -
“They were amazingly efficient, friendly, professional, and even re-inspected their own work to make sure everything was 100% perfect.”- Chris A.
Perfectionists!
"This company was referred to us by another plumbing contractor in San Diego.. so that says something right there. Justin came in and handled our laundry list from our home inspector. He reviewed all the work, the charges associated with it and helped to navigate what really needed to be done. They were amazingly efficient, friendly, professional, and even re-inspected their own work to make sure everything was 100% perfect. This is a high-quality company offering great services and fair pricing on all work performed. We are excited to have found our new local plumbers for any and everything in our home"- Chris A.
