What is backflow prevention?

Many people become sick and some die each year as a result of drinking water that has become contaminated through unprotected cross connections. A cross connection is any connection between your drinking water supply and anything else that could allow the water to become contaminated or polluted.

The reversal of flow through an unprotected cross connection into the drinking water system is called backflow. Backflow prevention is the elimination of unprotected cross connections or protecting cross connections that can't be eliminated with an approved method of backflow prevention.The ultimate goal of backflow prevention is to protect your health and safety by protecting the quality of your drinking water supplies after they have been delivered to you.
