What Is a Backflow Preventer—and Why Should Carbonado Homeowners Care?
If you’ve never heard of a backflow preventer, you’re not alone. Many Carbonado homeowners don’t realize they need one—until it’s too late.
A backflow preventer is a critical device in your plumbing system that stops contaminated water from flowing backward into your clean water supply. Backflow can occur when there’s a sudden drop in water pressure (such as during a water main break or when firefighters use a hydrant), and contaminated water from garden hoses, toilets, or irrigation systems can be siphoned into your drinking water.
According to the Centers for Disease Control and Prevention (CDC), backflow is a real risk that can lead to serious health hazards if not properly addressed.

Real Risks of Backflow in Carbonado
Backflow isn’t just a big city problem—it’s a rural and suburban issue too, especially in towns like Carbonado with mixed-use properties, wells, irrigation systems, and older plumbing infrastructure.
Here are a few real-life scenarios where backflow can happen:
- Hose backflow: A garden hose submerged in a pool, pond, or bucket of soapy water can siphon that contaminated water into your plumbing during a pressure drop.
- Sprinkler systems: Lawn irrigation systems without proper backflow protection can allow fertilizers, pesticides, or animal waste to back up into your drinking water.
- Boiler systems: Backpressure from heating systems can force tainted water into your clean supply.
Why Backflow Prevention Is Required (and Smart)
Local and national plumbing codes—including the Washington State Plumbing Code—require backflow preventers in certain situations, particularly when cross-connections exist. This means if you have:
- An irrigation system
- A fire suppression system
- A swimming pool
- A well or auxiliary water supply
You likely need a backflow prevention device installed and tested annually.
💡 Pro Tip: Want to know if your home already has a backflow preventer installed? Our Carbonado plumbing experts can inspect your system and let you know exactly what’s needed.
How a Backflow Preventer Works
Think of a backflow preventer like a one-way valve for your plumbing system. It allows clean water to flow in but automatically stops water if it tries to flow in the opposite direction. There are different types depending on your plumbing setup, including:
- Air gaps
- Double check valve assemblies (DCVAs)
- Reduced pressure zone (RPZ) assemblies
Each is suited to different levels of risk and usage. For most residential homes in Carbonado, a DCVA is often sufficient, while properties with higher hazard systems may need an RPZ.
Annual Testing: It’s Not Just for Commercial Properties
In Washington State, annual backflow testing is often required by local municipalities and water purveyors. While some homeowners think this only applies to businesses, residential homes with irrigation or cross-connections are included.
Testing ensures the device is working properly, and the inspection must be done by a certified backflow tester.

The Health Risks Are Too Big to Ignore
If backflow happens and there’s no preventer installed, the contaminated water can include:
- Pesticides and lawn chemicals
- Fecal bacteria
- Industrial or agricultural waste
- Soap, grease, and other pollutants
This can cause serious illnesses, especially for children, older adults, and immunocompromised individuals. It’s a public health issue that affects not only your home but also your neighbors.
