Backflow Prevention Installation

Protecting Your Drinking Water

Quality of drinking water is important to everyone and there are ways to keep your water supply safe. The “Protecting Your Drinking Water” article deals with cross connections associated with automatic sprinkler systems. This article also covers the installation of backflow prevention assemblies, the testing procedures required for a backflow assembly, and the training required of all testers for state certification.

Backflow Prevention Alternatives for Home Irrigation Systems (Irrigation Safety)

Irrigation systems make watering lawns and gardens easier and save time, but water that may be contaminated by weed killers and/or fertilizers can be back-siphoned (backflow) into your drinking water. Irrigation systems not protected by approved backflow prevention assemblies could endanger the health of a household, neighborhood, or community.

Please note that all irrigation systems - new or existing - must be equipped with an approved backflow prevention assembly. Only properly installed, state-approved backflow prevention assemblies meet the plumbing code and provide health protection for your family and neighbors. Your local water utility can give you a free list of state-approved assemblies and certified testers.
