What size sprinkler do I need for my application?

There are several points to consider when ordering sprinklers: First, it is important to choose a sprinkler that will match your water source's capability. You will need to have an idea of the water source's output in terms of gallons per minute and pressure. All sprinklers have a range of output specified by the manufacturer. Second, determine the area size to be watered and choose a sprinkler that will effectively cover your area based on the performance characteristics of the sprinkler and your water source's output capability. Matching sprinkler size and capability to your water source is critical to achieving good sprinkler performance.
