Backflow assemblies keep you, your family and our water safe.

The easiest way to keep you and your family safe from the potential hazards of backflow is to not create cross connections. However, if you do have a cross connection to a lawn sprinkler system, boiler, pool, water feature, have an approved backflow prevention assembly installed. After installation, have the backflow assembly tested by a State Certified Backflow assembly tester. This test is required each year in order to comply with state health and plumbing codes. 

A permit is required to install a backflow device.

To submit a permit, provide the following item.

  • Permit application
