Protect your home’s water supply and conform to City of Lynden and Whatcom County codes with a durable outdoor faucet vacuum breaker from Westside Building Supply.
Keep Your Outdoor Water Safe
An outdoor faucet vacuum breaker is a simple addition that helps protect your home’s drinking water. Installed on an exterior faucet, it prevents contaminated water from being pulled back into your plumbing when water pressure changes. It’s a small part that can make a big difference during everyday tasks like watering the lawn or rinsing outdoor equipment.
A vacuum breaker also conforms to Washington’s Cross Connection Codes that require backflow prevention for outdoor faucets, irrigation, swimming pools, fire sprinkler systems, wells, and other connected water supplies. Most cities in Whatcom County, including Lynden, Ferndale, Bellingham, Nooksack, Blaine, Everson, and Sumas, require backflow prevention.

How a Vacuum Breaker Prevents Backflow
A vacuum breaker opens automatically when water pressure drops. Instead of allowing water to flow backward through a connected hose, it draws in air to stop the reverse flow.
That extra layer of protection matters because hoses are often connected to sprinklers, buckets, pools, or garden sprayers. Without a vacuum breaker, water containing dirt, fertilizer, or cleaning products could be pulled into your household plumbing during a sudden pressure loss.
Types of Outdoor Faucet Vacuum Breakers
Choosing the right outdoor faucet vacuum breaker starts with understanding how each style is used.
Hose connection vacuum breakers screw directly onto a standard outdoor faucet and are a popular choice for most homes because installation is quick and replacement is simple.
Atmospheric vacuum breakers are commonly used on irrigation systems or outdoor plumbing that stays above ground. They provide reliable backflow protection but must be installed in the correct position to work properly.
Freeze-resistant models are designed to handle colder weather better than standard versions. They still need proper winter preparation, but they can help reduce damage caused by freezing temperatures.

Frequently Asked Questions
Can hard water damage a vacuum breaker?
Yes. Mineral deposits can collect inside the device over time, making it harder for the internal parts to move freely. Periodic cleaning or replacement may be needed in areas with hard water.
Why do some vacuum breakers have tamper-resistant screws?
Many models include breakaway or tamper-resistant screws to discourage removal after installation. This helps keep the device in place and maintain backflow protection.
Can a vacuum breaker reduce water pressure?
Under normal conditions, the difference is minimal. A noticeable drop in pressure may indicate mineral buildup or a worn-out vacuum breaker, which should be inspected.
Is a vacuum breaker required on every outdoor faucet?
Local plumbing codes vary, but many jurisdictions require backflow protection on exterior hose connections. Checking local code requirements before replacing an outdoor faucet can help avoid future corrections.
