Adjusting the spray angle, also known as the arc, on a sprinkler head typically involves interacting directly with the sprinkler head or its nozzle. This process allows you to control the coverage area of the water spray.
Different types of sprinkler heads, such as rotors and spray heads, have varying methods for adjusting the arc. However, the adjustment point is usually located on the top or side of the sprinkler head itself.
Understanding Sprinkler Head Adjustment
Most adjustable sprinkler heads require a specific tool, often a small flathead screwdriver or a specialized sprinkler adjustment tool provided by the manufacturer. The adjustment mechanism is usually a screw or a collar located near the top of the sprinkler head or on the nozzle.
Common Adjustment Points
- Rotor Heads: These often have a screw that controls the water stream break-up and sometimes influence the arc. The arc adjustment itself is frequently done by rotating a collar or using the tool to turn a specific slot or keyhole on the head while it is running or popped up. You might also need to set a fixed 'left' or 'right' stop point before setting the arc range. As seen in instructional content, adjustment often focuses on this nozzle, potentially interacting with a part to the left, to change the spray arc.
- Spray Heads (Adjustable Nozzles): Nozzles on spray heads often have a collar or ring at the base that can be rotated by hand or with a tool to expand or reduce the spray arc. Some might have a small screw on the top that primarily adjusts the spray distance but can also slightly affect the pattern.
Steps for Adjusting the Arc
While specific steps vary by model, here is a general approach:
- Identify the Adjustment Point: Locate the screw, slot, or collar on your specific sprinkler head model. Refer to the manufacturer's instructions if available.
- Use the Correct Tool: Obtain the appropriate adjustment tool.
- Make Small Adjustments: Turn the screw or collar incrementally. A small turn can make a significant difference in the arc.
- Test the Coverage: Turn on the water to observe the new spray pattern and coverage area.
- Refine as Needed: Continue making small adjustments and testing until the desired arc is achieved, ensuring overlapping coverage with adjacent sprinklers.
For example, in some heads, focusing on this nozzle the left refers to a specific screw or tab you interact with on the left side of the nozzle or head to widen or narrow the spray pattern. Always make adjustments carefully to avoid damaging the sprinkler head components.
