Description
The Watts 29YL78 Vacuum Breaker LF288AC prevents vacuum conditions from drawing water backward through compatible piping. It allows air into the water line when low pressure forms, separating the downstream water column from the upstream supply. The 1/4-inch connection provides the specified interface for compatible piping or equipment connections. The breaker installs on HVAC systems hydronic or water-service piping where backflow protection is required. This operation maintains the intended flow direction, reduces reverse water movement, and supports protection of connected water circuits during pressure changes or interruption of normal flow.
