If you are on a city water line, there is most likely a backflow prevention device in your home. These devices ensure that the water in your home lines does not backflow into the main water supply. In most cases this is not an issue. The pressure from the main water supply is usually much greater than your home water lines, preventing backflow. However, it certain circumstances, this may not be the case so a backflow preventer can stop your water from entering the city water supply. In many cities, there are codes requiring homeowners to install and maintain a backflow preventer in their home, or face a penalty.
Why is a Backflow Preventer Needed?
You may be wondering why backflow prevention is such a big deal. What difference does it make if your water goes back into the main water supply? It is a way to avoid accidental contamination. For example, if the pressure is reduced from a main line break or other situation in the water supply, a suction can occur pulling water from every area of your home, even your irrigation system. This can inadvertently pull contaminants like fertilizers and pesticides into the community water system.
Meeting Local Backflow Prevention Codes
If you are not sure what the codes are in your city regarding backflow prevention, talk to your local sewer service provider. They can educate you on what is needed to meet city codes. This can involve installing a backflow preventer, having backflow testing and annual inspections. Most experienced sewer service providers can provide the needed installation, testing and inspections to ensure that your home is following the backflow prevention codes for your city.
