If you don’t have a backflow prevention device on your irrigation system, you should have one. All irrigation systems are required to have a backflow prevention device. Although a dual check and double check sound the same they are very different. A double check backflow prevention device offers you the highest level of protection for you and your family from a potentially toxic situation. A double check is not meant for a situation such as this. Not sure if you have either – check near your water meter for a device that looks like this one. If you don’t have it, for the safety of not only your family but everyone around you, get one.
