Home Sprinkler Safety

Home Sprinkler Safety
While sprinkler systems make it easy to water lawns and gardens, they also pose a potential risk. Without the proper plumbing equipment, water can flow backward (backflow), allowing contaminated water from your sprinkler system to flow into your home’s drinking water supply and water mains.

Install a backflow preventer, to keep your water drinkable.

All sprinkler systems must be equipped with a properly installed, state approved backflow preventer to meet the requirements of Oregon plumbing code requirements. The City provides home sprinkler safety information by issuing a no fee permit. Also, all sprinkler systems fed by public water systems need a plumbing permit before installation.

Annual testing is needed for all assemblies, except atmospheric vacuum breakers, to ensure safe operation and health protection.

Learn more about keeping your water drinkable on the Water Distribution Division webpage.
