Installation Guidelines
This atmospheric vacuum breaker (AVB) must be installed a minimum of 6 inches above the highest point of the downstream piping to ensure proper functionality and prevent backsiphonage.
It is crucial that no shutoff valves are present downstream of the AVB, as this can impede its operation and compromise protection.
The Watts 3 inch Lead Free Anti-Siphon Vacuum Breaker Backflow Preventer is designed to prevent the reverse flow of polluted water into the potable water supply due to backsiphonage. This device is suitable for both hot and cold water applications.
Construction
Features lead free brass construction for safe use in potable water systems.
Equipped with a chemical resistant silicone seat disc and a chrome hood for durability.
An atmospheric vent prevents spilling, even under low flow conditions.
Performance & Design
Designed with a full size orifice to ensure pipe size capacity and maximum flow with minimum pressure loss.
The lightweight, durable disc float is suitable for temperatures up to 180°F (82°C) and effectively closes the atmospheric vent to prevent spilling under all rates of flow.
Specifically designed to prevent spilling due to surges and other atmospheric conditions, ideal for equipment that uses small amounts of water.
Applications
Ideal for low flow, non-continuous hot or cold water health hazard applications, such as on laboratory equipment.
