    Backflow Testing

    Why does your backflow preventer need to be tested every year? It’s a question we hear often from frustrated businesses and homeowners. It may seem like a huge waste of time and money to have your backflow prevention device tested annually, but there is a good reason.

    Backflow preventers are devices that ensure that your water only flows in one direction through your pipes. Without a backflow preventer, a sudden increase in pressure in your plumbing system or a sudden pressure drop in the water supply line could cause your water to flow backward into the public water supply. This has the potential to introduce hazardous contaminants into the public water supply. No one wants that! .


    Backflow is just what it sounds like – It’s when water in your building or home begins to flow backward into the public water supply. This can introduce contaminants into the public water supply system, hence why having a backflow prevention device is so important.

    A backflow prevention device works in such a way that it allows water to flow in one direction only, preventing it from flowing backward and contaminating the public water supply.. Your backflow prevention devices must be properly tested and maintained annually by a technician that is certified by the county health department to ensure that it is functioning properly.


    In Southern California, many cities require that commercial properties have a backflow prevention device installed and that backflow testing be performed by a technician that is certified by the jurisdiction’s health department. Why? This is the best way to ensure that public drinking water is not contaminated. Most cities require annual backflow testing, if not more frequent testing depending on the location and the specific industry.

    For residential customers, backflow devices must only be installed in certain circumstances. If your plumbing system is connected to one of the following devices, you’ll likely be required to have a backflow device installed as well:

    • Sewer ejection pump
    • Septic tank
    • Groundwater well
    • Graywater system
    • Rainwater collection system
    • Recycled water system
