Pressure Vacuum Breaker

Help reduce vacuum and prevent backsiphonage of contaminated water into the water supply with these breakers. Commonly used in residential applications, these breakers are often installed on a bibcock or flush valve to help prevent contaminated water from flowing back into the public water system.

Install these breakers in heating and plumbing applications for excellent resistance to corrosion and chemicals.

Prevent vacuum from occurring in enclosed tanks, which can lead to unintended siphonage, potential collapse of storage containers, or filter and instrument damage with these breakers. They are constructed of durable plastic material that can withstand corrosion caused by ultrapure liquids and some chemicals.

Screw these devices directly onto a faucet where hoses are attached to reduce vacuum and prevent backsiphonage into the water supply. Designed for use in irrigation, swimming pools, laundry facilities, and other applications that use portable hoses.

These vacuum breakers have 2 check valves with an atmospheric port in-between for added protection against contaminated backflow into the water supply. Connect to faucets in laboratory sinks and other applications with increased contamination risk.

Designed for extra protection against backsiphonage into the water supply, these dual check valves also feature a manual drain port to prevent freezing. Connect to faucets on outdoor service sinks, dispensers, and frost-proof hydrants.

Use these vacuum breakers on indoor factory machines or chemical dispensers to protect the water supply from contamination due to backsiphonage and to prevent spillage, typically during startup operation.
