Be Responsible....
As a consumer, you have a responsibility to maintain your plumbing system to keep the water safe for drinking. If you have any type of cross connection which could pose a health risk to others, you should eliminate it. A cross connection is a link between a potable water source and a non-potable water source. During a backflow incident, a cross connection could put toxic chemicals, bacteria or other pathogens back into our drinking water system. It is very important to your health and the health of others to follow all Department of Health rules and regulations to ensure clean and safe drinking water for our community.

What is Backflow? The undesirable reversal of flow of water and other liquids, gases or other substances in the distribution system of the potable supply of water.
What is Backpressure? Any elevation of pressure in the downstream side piping system that would cause a reversal of the normal direction of flow.
What is Backsiphonage? A form of backflow due to a loss of system pressure, pulling water backwards.
When does a backflow device need to be tested? A device needs to be tested upon initial installation, when it is moved, when there has been a backflow incident, and after a repair has been made. In the State of Washington, it is required that they be tested at least annually.
Why is Annual testing required? Backflow assemblies are a series of valves and checks that need to be tested and maintained on a regular basis to ensure they are working properly. Without all components of the device working in conjunction with each other, it may not do it's job in the event of a backflow incident. The State requires annual testing of these assemblies to keep people safe.
Why do I need a backflow device? Water that is used for irrigation, in a boiler, or fire sprinkler system is usually connected directly to a potable water supply line. If there were a backflow incident, fertilizers or animal fecal matter could be pulled back through the irrigation lines into your drinking water. A properly working backflow device will eliminate that risk. Backflow assemblies are a reliable safeguard for you and your family.

Types of Backflow Assemblies
Reduced Pressure Backflow Assembly - RPBA provides the most protection against backpressure and backsiphonage conditions. It consists of 2 spring loaded check valves that close under no flow or backflow conditions, and 1 relief valve that will discharge water during an incident. This assembly is used for either high or low health hazards.
Double Check Vavle Assembly - DCVA provides protection against both backpressure and backsiphonage conditions, but is only used in low health hazard applications. It consists of 2 spring loaded check valves that close during no flow or backflow conditions.
Pressure Vacuum Breaker Assembly - PVBA provides protection against backsiphonage only, and consists of 2 check valves and a poppet that closes to stop water flow when pressure drops in the line. It can be used for either high or low health hazards.
Spill Resistant Vacuum Breaker Assembly - SVBA is used to protect against backsiphonage only, but can be used for either high or low health hazards. It consists of one check valve and a float valve that closes under backsiphonage conditions.
