When it comes to protecting your drinking water in Edgewood, backflow prevention isn’t just a recommendation — it’s a necessity. Whether you own a home, run a small business, or manage a rental property in the Tacoma area, knowing how backflow works and why prevention matters can help you avoid costly plumbing issues and serious health risks.
In this post, we’ll explain what backflow is, how it affects your plumbing system, and what you can do to keep your Edgewood home safe and compliant with local regulations.
🔄 What Is Backflow?
Backflow happens when the flow of water reverses direction in your plumbing system, causing contaminated water to enter your clean water supply. This typically occurs due to backpressure (when pressure in your plumbing system exceeds that of the main water supply) or backsiphonage (a sudden drop in water pressure, like during a water main break).
Example: If a hose submerged in a chemical solution is left connected to a faucet during a pressure drop, contaminated water can be sucked back into your home’s drinking water.
🚱 Why Backflow Prevention Matters in Edgewood, Tacoma
Edgewood homes are part of the greater Tacoma water infrastructure, which includes thousands of residential and commercial plumbing connections. Without proper backflow prevention, there’s a real risk of pollutants, pesticides, chemicals, or sewage infiltrating your potable water.
🔍 Potential contaminants include:
- Pesticides from lawn irrigation systems
- Cleaning chemicals from dishwashers or laundry systems
- Fecal bacteria from cross-connected sewer lines
- Heavy metals or industrial byproducts from nearby commercial facilities
🏡 Local Relevance in Edgewood:
Edgewood’s semi-rural neighborhoods, with larger lots and irrigation systems, are particularly vulnerable to backflow events if not protected. Homes with wells, sprinkler systems, or pools are required by law to install backflow prevention devices in many cases.
🛠️ What Is a Backflow Preventer?
A backflow preventer is a device installed on your plumbing system to keep water moving in only one direction. There are several types, but the most common in residential applications are:
- Atmospheric Vacuum Breakers (AVBs)
- Pressure Vacuum Breakers (PVBs)
- Double Check Valve Assemblies (DCVAs)
- Reduced Pressure Zone Assemblies (RPZs)
These devices are often installed near irrigation systems, hose bibs, or main water lines, and require annual testing in most areas—including Pierce County.
🧪 Tacoma & Washington State Requirements
In Washington State, including the Edgewood and Tacoma regions, the Department of Health mandates annual testing of backflow devices by certified testers.
💡 Did you know? The Washington State Department of Health recognizes backflow as a major risk to public water systems and enforces strict regulations to protect communities.
