What color is the entire siamese connection of a non-automatic sprinkler system painted?

In New York City, the entire siamese connection of a non-automatic sprinkler system is painted aluminum. This specific color coding is established to denote that the connection is intended for fire department use, allowing quick identification during an emergency. The aluminum finish helps with visibility and can withstand various weather conditions, ensuring that the connections remain functional and recognizable when needed for firefighting efforts.

The other color options such as red, white, and yellow are associated with different types of systems or components in fire protection. Red is typically used for standpipe systems, white is often reserved for indicating water supply systems, and yellow may indicate other specific uses or hazards. Knowing the correct identification colors is crucial for safety and effective response in emergencies.
