Adjust the flow of water at the source. Opening the faucet to increase the water flow will increase the power and coverage of the stream, while decreasing the flow will confine the sprinkler coverage to a smaller area. Use a lower water flow when you want to avoid damaging delicate plants, like flowers and leafy shrubs, with a forceful blast.
Change the position of the diffuser pin. The diffuser pin is a large screw anchored to the base of the sprinkler head. If you want to decrease the distance that your sprinkler covers, screw the pin in a clockwise direction until it sits over the water nozzle. For a more concentrated stream that will go further, unscrew the pin all the way or remove it entirely.
Raise or lower the deflector shield. Swivel the flat metal square attached to the body of the sprayer head just beside the diffuser pin up or down. When the stream hits the downturned deflector shield, it will be redirected into a lower arc perfect for watering nearby plants and patches of grass.
This will allow the stream to travel in a higher arc and cover longer distances. Use the friction collars to alter the spray pattern. Twist the metal clamps that wind around the base of the sprinkler head into different positions to determine the movement of the sprinkler head. The closer together the collars are, the narrower the watering range. Make sure the trip pin stays within the range you want to set for the sprinkler. That way you can water the rose bushes outside your home without dousing the front porch or the garage door.
Flip up the trip pin for full degree coverage. If you want the sprinkler to rotate all the way around, simply lift the trip pin until it rests up against the sprinkler head. It will then be able to send out water in a smooth, radial motion. Adjust the distance control dial. Some impact sprinkler models feature a separate dial that allows users to manually set the desired spray distance.
If your sprinkler has one of these dials, turning it to the left will reduce the force of the stream, while turning it the right will pressurize it to send it further.
Method 2. Make sure you're using a water source with a pressure of at least 15 psi. Most residential areas have an average water pressure somewhere between psi.
However, yours might be lower if you get your water from a pump or well. Choose the right sprinkler head. Impact sprinkler heads are usually sold in a couple different materials—plastic and metal. Plastic heads are lightweight, making them easier to turn with a conservative water flow of around psi. While they tend to be slightly more expensive, metal heads will be better able to handle the strain of higher pressures. Clean your sprinkler periodically. A new sprinkler that has stopped performing to its usual standard may just be in need of a good cleaning.
Remove the sprinkler head from the base and disassemble it to gain access to the nozzle and swivel bearing. A mixture of vinegar and warm water can cut through heavy mineral and sediment deposits that have accumulated inside the sprinkler head.

Turn the garden hose on to your sprinklers, or the irrigation system for pop-up sprinklers, to observe the coverage and spray pattern.
Make additional adjustments as necessary to avoid watering driveways and walkways, and provide full coverage with no overlapping water spray from each nozzle.

Impact sprinklers are brass or plastic and have a characteristic ticking sound when they rotate from the end of one arc to the beginning of another.
Use a pulsating sprinkler on a riser to increase the distance of water throw in vegetable gardens or large landscaping beds. Connect multiple garden hoses in succession to stand-alone, in-line pulsating sprinklers to cover larger areas of your lawn.
Overlapping spray patterns can lead to fungus in your lawn and harm your turf grass. There are five general types of sprinklers: stationary, oscillating, impulse, rotary, and traveling. Impulse sprinklers, also called pulsating sprinklers, are ideal for watering larger areas. The slow, gentle watering they provide is the preferred method of lawn care professionals for watering private lawns, landscaping , and golf courses.
Pulsating sprinklers disperse water from a single jet, and are usually adjustable for watering in full circle and partial circle patterns. Most models are typically adjustable for the distance of throw as well. A freestanding pulsating sprinkler head can be connected to any standard, above-ground hose.
These sprinklers come in two basic designs: those with a sled base and those with a spike base. Pulsating sprinklers with sled bases, also called H-bases, are best suited for smaller areas and where water pressure isn't excessive.
