A-A Backflow Testing and Maintenance, located in Torrance, is a superior service provider for property managers, industrial plant managers, government, commercial, maintenance providers, residences and others that need to comply with the annual testing of backflow devices required under California state law. We are the backflow company for your needs!

We use County approved procedures to provide HONEST tests to insure that your device meets the required standards. You are welcome to witness any test!

We work on all approved devices and can replace any obsolete device with one that is on the most current approved list.

Backflow devices are designed to maintain water quality by keeping pollutants and contaminates from entering the drinking water supply. Water Districts are required by the EPA and the State of California to implement a Cross Connection Control Program. We help reduce your liability by making sure your device is working properly.

Some examples of pollutants and contaminants are irrigation water, pesticides,  cleaning agents, water conditioners for boilers, X-ray developer, fire supply lines,  soda machines, etc.

We test and service the following types of backflow devices:

  • Pressure Vacuum Break PVB
  • Spill Resistant Vacuum Break SPVB
  • Double Check DC
  • Reduced Pressure Principle RPZ
  • California Water has additional field personnel and is requiring backflow installations for meter protection. Letters are being sent out weekly.
  • California Water tests are going to be mailed soon and will be due June 15, 2016
  • Government and school jobs - we are DIR-PWC registered and can do prevailing wage jobs
  • Los Angeles County Health Department will now accept copies of their test form. In addition the following changes are being made
    1. The $31 fee per device will now be enforced by the County Tax Collector. This is a per device fee that must be paid to avoid a tax lien and does not have to do with testing.
    2. The County will now enforce the testing requirement by turning off water service for non-compliance.
  • Golden State Water has sent numerous letters that require installation of new backflow devices.
