What is the difference between residential and commercial sprinkler heads?
Residential sprinkler systems are typically less complex than commercial sprinklers. They are usually connected to the domestic water supply and may have smaller sprinkler heads that blend in with the home’s aesthetics. The standards and requirements for residential fire sprinkler systems can be found in NFPA 13D. The most common types of fire sprinkler systems are wet, dry, deluge, and preaction, each with its own unique characteristics and applications. Let’s take a closer look at how these systems operate and the key differences between them.Types of sprinkler systems permissible by NFPA 13, Standard for the Installation of Sprinkler Systems, are wet, dry, preaction, and deluge. Other types of extinguishing systems, such as clean agent or water mist, are addressed by other standards.We have provided a detailed comparison of four of the most common types of commercial fire sprinklers: wet pipe, dry pipe, deluge, and pre-action systems. Understanding these systems is the first step in making an informed decision to protect your commercial property.

Which type of sprinkler head is best?
Matching Sprinkler Heads to Landscape Conditions Turf areas usually work best with sprays or rotors, while shrubs often benefit from drip or micro-irrigation to reduce water waste and prevent plant damage. Different types of sprinklers are most effective to water different planting areas of the home grounds. For grass, pop-up and rotor sprinkler heads are generally used. Other types include drip emitters and micro- spray heads for shrub areas, flowerbeds, and vegetable gardens.
