Which sprinkler head type is most commonly used in residential settings?

The most commonly used sprinkler head type in residential settings is the pendent or upright sprinkler heads. These types of sprinklers are specifically designed for residential applications due to their effectiveness in providing adequate coverage and their adaptability to various ceiling heights and designs.

Pendent sprinkler heads, which hang down from the ceiling, are particularly effective at distributing water over a wide area when activated. On the other hand, upright sprinkler heads are positioned upright and are typically used in locations with high ceilings or in areas where the risk of exposure to waterlines is a concern.

Their design and functionality make them suitable for residential environments, as they can be installed in different locations in a home, including living rooms and kitchens, ensuring comprehensive fire protection.

In contrast, early suppression fast response (ESFR) sprinklers are intended for industrial use, where they can quickly suppress a fire in high-risk settings. Standard spray heads can be used in various applications but are less common in residential settings compared to pendent or upright varieties. Dry pipe sprinkler heads are generally utilized in environments where the risk of freezing is present and are not typically found in standard residential installations.
