A lot of those free design guides you find in stores and on the Internet get this wrong. That’s right, 100% overlap of watered areas is REQUIRED or you will get dry spots! This is known in the industry as “head-to-head coverage or head-to-head spacing”. That means each sprinkler throws water ALL the way to the next sprinkler in each direction. Sprinklers are intentionally designed to require 100% overlap of watered areas. Have Doubts? See for yourself, it only takes a couple of minutes to prove! Grab a piece of paper and draw circles on it so that all areas of the paper are inside a circle, but no circles overlap. Without this overlap it would be impossible to design sprinkler systems that provided uniform water coverage. This overlap may seem like a waste at first, but it is a very important necessity. The area watered by each sprinkler must overlap substantially the area watered by the adjacent sprinkler. This is important, read it carefully! Sprinkler Coverage:
