FAQs

What is the primary function of the Watts LF288AM4 vacuum breaker?

Its primary function is to prevent backsiphonage, which is the reverse flow of contaminated water into a potable water supply, particularly in hot or cold water systems.

Is this vacuum breaker suitable for continuous pressure applications?

No, the Watts LF288AM4 atmospheric vacuum breaker is not designed for continuous pressure and should not be subjected to continuous pressure for more than twelve hours per ASSE Std. 1001.

What materials are used in the construction of this device?

The body is constructed from Lead Free* brass, and it features a durable chemical-resistant silicone seat disc for reliable performance.

Where should this atmospheric vacuum breaker be installed?

It must be installed a minimum of 6 inches above the highest point of the downstream piping. It is also crucial that no shutoff valves are placed downstream of the device.

Does this device protect against backpressure backflow?

No, atmospheric vacuum breakers are not designed, tested, or approved to protect against backpressure backflow. For backpressure protection, different types of backflow preventers are required.
