Backflow Testing & Certification in Oceanside
Serving San Diego, Riverside, & Orange County
A backflow prevention device is designed to protect your water supply from backflow pollution and contamination. Because this system is critical to your health, it is important to ensure it is installed, tested, and repaired by licensed, bonded, and certified professionals. At American Plumbing Heating & Air Conditioning, our Oceanside plumbers are approved to perform backflow inspections and can even certify your system on the same day.
Importance of Backflow Certification & Testing
Local, state, and federal regulations require your backflow prevention devices to be certified and tested after being installed on your property. Every backflow preventer must comply with specific health and safety codes to ensure the quality of your water.

“Thank you all so much for taking such good care of us!”- Trina
Spectacular Job
"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!"- Trina -
“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. -

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 -
“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. -
