What Is a Vacuum Breaker?

A vacuum breaker is a device designed to prevent backflow by attaching to the outlet of an outdoor hose tap. It's job is to prevent a process known as siphonage, which happens when a sudden drop in water pressure creates a vacuum in the water supply.

How Can Water Become Contaminated?

Many people are unaware of how frequently a garden hose can come into contact with substances that should never enter a drinking water system. If a hose is left in a bucket of detergent, a swimming pool, a muddy garden bed, a pond, or even a pet's water bowl, it can pose a contamination risk if back-siphonage occurs.

Are Vacuum Breakers Required in Queensland?

Yes—when there is a risk of contamination, Australian plumbing regulations mandate the installation of suitable backflow prevention devices. For most residential outdoor hose taps, an approved hose connection vacuum breaker offers the necessary level of protection.

Is Your Hose Tap Protected?

Many older homes either don't have a vacuum breaker fitted or have one that has been removed, damaged, or no longer functions correctly. Because they're exposed to the weather and frequent use, these devices can wear over time and should be inspected periodically.
