Fill out the online survey here: Backflow Cross Connections Survey
A cross connection is defined as an actual or potential connection between a public water supply and a source of possible contamination or pollution. All properties have potential cross connections. This can lead to serious health hazards when a backflow condition occurs. Backflow can happen when the flow of water into your home or business is reversed by a sudden drop in pressure. Water pressure can suddenly drop because of heavy usage, fire hydrant use, or a broken water main.
You can prevent backflow, and contamination, from happening to your water supply by installing a backflow prevention device. Common backflow prevention devices include:
Installing a backflow prevention device is not a fix-it and forget-it solution. There are testing requirements you need to follow. City Ordinance #5401 requires backflow prevention devices to be tested as listed below. Note: Hose bibs and anti-siphon faucets are not testable
So, how do you know if you already have a backflow prevention device installed at your home or business? If you have an underground sprinkler system, you likely have a pressure vacuum breaker (PVB) style device. Commercial properties are more likely to have reduced pressure zone (RPZ) or double check valves, we don’t typically see these homes. If you’re not sure, you can contact the Department of Utilities Water Department at 402-727-2613.
Now that you’ve identified if you have a backflow prevention device, which style you have, and what the testing requirements are; you’re likely wondering how do you get it tested and when? City Ordinance #5401 states, “All tests shall be done by a Backflow Preventer Test and Repair Technician, Grade VI Water Supply Operator, certified by the State of Nebraska Department of Health.” Your plumber can help you with this. The Department of Utilities is required to keep records of these tests and will issue reminder notices when testing is due.
