Want to avoid brown spots on your lawn? Head-to-head spacing is vital to getting an even amount of water and without over-watering in the process. But you have to make sure you have proper spacing? Below are a few tips to get spacing just right.
As the name implies, head-to-head means the spray from each sprinkler head overlaps the spray from the sprinkler head beside and across from it. If the spray is not overlapping this is called using a “stand alone” method and you will probably see those brown doughnuts due to insufficient watering. The actual distance between the sprinkler heads is determined through knowing what the water pressure of your system is, and what the gallons per minute of the nozzle will be as well. You can test these two things by performing a static pressure test and bucket test.
The most common type of spacing is called, “square spacing” because it looks like a square when you draw a line between four sprinklers and each of the squares that are formed will receive spray from four different heads. This is a great method to use for a landscape that is roughly square or rectangular. The other common type of spacing is called, “triangular spacing” because if you draw a line between three adjacent sprinklers it looks like a triangle. This method is great for large open areas, but is difficult to fit the spacing in smaller areas.
