Description
Midland 3/4" Vacuum Breaker
Midland 3/4" Vacuum Breaker is designed to help protect potable water systems from backsiphonage by preventing contaminated water from being drawn back through a hose connection.
Designed for installation on compatible hose bibbs, sillcocks, and outdoor faucets, this compact vacuum breaker uses standard 3/4" hose thread connections for quick installation. When water flow stops and a vacuum condition develops, the device is designed to admit air and interrupt the siphoning action.

How It Works
Normal Water Flow
During normal forward flow, water passes through the device to the connected hose or accessory.
Vacuum Condition
If supply pressure drops and backsiphonage begins, the vacuum breaker is designed to open its air inlet.
Siphon Interruption
Admitting air helps break the siphoning action so contaminated downstream water is less likely to be drawn into the potable water system.
Construction Details
The vacuum breaker uses a compact threaded body designed for installation directly onto compatible 3/4" hose thread outlets.
Its internal mechanism automatically responds to pressure changes by admitting air when a vacuum condition develops downstream.
Corrosion-resistant construction helps support dependable service in residential and commercial outdoor water applications.

Backsiphonage vs. Backpressure
Backsiphonage
Backsiphonage occurs when supply pressure drops below downstream pressure, creating a vacuum condition that can draw water backward into the potable water system.
Backpressure
Backpressure occurs when downstream pressure becomes greater than supply pressure. This vacuum breaker is specifically described for backsiphonage protection, so application requirements should be verified before installation.
Our valve, fitting, and industrial product specialists can help review your valve size, FIP connection requirements, pressure rating, handle configuration, media compatibility, and application before you order.
