Backflow FAQs

Your Role in Backflow

Property and business owners are required to install and maintain backflow prevention devices where they are needed. It is also required to have the backflow device tested annually by a Certified Backflow Tester. 

Please reference WAC 51-56-0600 or WAC 246-290-490

When Do You Need a Backflow Preventer?

A backflow device is required where there is any possibility of a cross connection between the public water system and a non-potable water source. Examples include; sprinkler systems,  boilers, and other water-using equipment.

Skipping Testing Risks

If a backflow device is not tested annually, Orchard Avenue can take action, starting with a $250.00 fine and termination of water service. We will make every effort to work with our patrons to avoid these actions from being taken, but we must ensure your drinking water is protected.

Backflow Testing Time!

Prevent Cross Connection

Cross connections provide pathways for contaminants to enter the drinking water supply.  

Backflow Risks

Backflow can happen at any time. This means contaminates can be introduced to the water system. Some contaminates are: pesticides, E. Coli, metals and more!

Potential Cross Connections

Anything connected to your water system can cause a cross connection. 

Examples: a hose submerged in water, sprinkler systems, boilers, swimming pools, water softeners and more!

Fire Hydrant Use

Using Orchard Avenue's fire hydrants will lead to a fine. Improper use can cause backflow due to the change in pressure.
