How far apart can residential sprinkler heads be spaced at maximum?

The maximum spacing for residential sprinkler heads is typically 12 feet, which allows for adequate coverage and effective suppression of fires. This distance ensures that the spray pattern from each head can overlap with adjacent heads, providing a more uniform distribution of water. Proper spacing is critical to achieve the desired effectiveness of the sprinkler system while also adhering to building codes and safety regulations.

In residential settings, spacing too far apart could result in dry spots that may not receive adequate water in the event of a fire, undermining the system's effectiveness. Conversely, having them too close together could lead to wasted water and possible system inefficiencies.

Understanding spacing also helps sprinkler fitters design systems that comply with National Fire Protection Association (NFPA) standards and local codes, ensuring safety and reliability in fire protection systems.
