Backflow Testing in Santa Ana

Helping You Maintain a Clean Water Supply in Southern California

One of the most important things you can do to protect the water supply at your business is backflow testing and backflow prevention. Backflow testing ensures that your backflow devices are working efficiently to keep contaminants out of your water. 

If you need help meeting backflow testing requirements, call Pacific Plumbing of Southern California. Our plumbers are trained and equipped to provide accurate backflow testing in Santa Ana and Orange County.

If you need backflow testing service, call (714) 699-9936 to set up an appointment. 

How Backflow Testing Works

Backflow happens when water flows in the opposite direction in the water system. This results in water that is not safe for consumption. Backflow testing is required by law. The process takes less than half an hour to complete and involves opening and closing the valves to identify any irregularities. Our highly skilled Santa Ana backflow testing plumbers will also test the water for contaminants to ensure that the device is working properly.

We perform backflow testing to ensure that:

  • The check valves are working to prevent backflow
  • The relief valves open when they should
  • The air ports in the backflow device open correctly

If a problem is noted with the backflow device, we will provide you with the results of testing and discuss what is wrong with the system. We take the time to fully explain the problem and any repairs that may be needed to ensure that your drinking water is protected. Our licensed plumbers in Santa Ana provide the necessary repairs to fix any irregularities, so you are in compliance with all regulatory requirements.
