How does the forum treat ESFR sprinklers when there is a wall added in the warehouse which creates the heads on one side to be too far away but when you add a new line it puts the ESFR sprinklers too close together? Some times there is that perfect storm where you can’t move the existing line over because over spacing / under spacing. In the past we have staggered the ESFR sprinklers on the new line to make the 8ft away on the diagonal.
