When a sprinkler system is designed, it should incorporate “head-to-head spacing.” This means the spray of one head should reach the closest heads around it to ensure an even distribution of water. These requirements are based on hazard level as well as pump flow calculations and may need to be adjusted based on any obstructions that may be present in the area of the sprinkler head. The process of cold soldering occurs when one sprinkler sprays water on another and cools it down so much so that the second sprinkler’s heat sensor is thrown off and delayed or deactivated.
