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.
Whether your water district has requested that you schedule backflow testing or you need to have a new backflow prevention device installed and certified, American Plumbing Heating & Air Conditioning is the team for the job. We are certified to work throughout the counties of San Diego, Riverside, and Orange County.
It is critical to have your backflow preventer certified and tested, even if it is designated for a:
- Fountain

- Fire hydrant
- Lawn irrigation system

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.
