Testing of Backflow Preventers

*** Notice *** Cross Connection (Backflow) Program *** Notice ***

If you are a homeowner who has a lawn irrigation system on your property, you have probably recently received a letter requiring the backflow preventer to be tested. The testing of these devices is necessary and required by Federal, State and local laws to assure that the device is working properly. Notices are sent based on when your sprinkler system was installed or last tested.

The backflow preventer, as its name indicates, prevents contaminants from back flowing into the City's water system and being distributed to you and your neighbors. The types of contaminants from a residential lawn that could get into the irrigation piping would include such things as animal fecal matter, fertilizer, insecticides, mosquito larvae or anything else that gets deposited onto the lawn. Below is a link to a short video that will help you understand this issue. On that same link are related videos and other useful information. The City would encourage you to price shop. Each company that does this testing sets their own fees and they do vary. They range from as low as $50 to as high as $150.

For more information please watch this short video.
