The point of your backflow system is to keep the water in your irrigation system from entering your potable water system The water used in your sprinklers often contains traces of pesticides fertilizers and other contaminants Simply put it isnt safe for human consumption

When your backflow preventer is working properly it only allows the water in your irrigation system to travel in one direction out towards your landscaping and never in towards your drinking water

However like any mechanism backflow systems require maintenance to ensure theyre working smoothly This is especially important in areas that get dry hot summers where homeowners will rely on irrigation systems to keep their lawns healthy Most towns and municipalities require periodic testing to keep drinking water safe For example

Cary North Carolina requires that a backflow prevention assembly receive annual testing
Raleigh North Carolina requires that irrigation systems be tested every three years by a city approved contractor
