Impact sprinkler heads sit on a rotating bearing, which allows them to pivot as water flows through them for full coverage.If you want to change the pressure, spray pattern, or arcs of the water in your impact sprinkler system, there are a number of ways you can do it.Control of the flow of water is the simplest solution.The different parts of the head can be adjusted to get the right strength and trajectory.
Step 1: The flow of water needs to be adjusted.
The easiest way to change the amount of water coming out of your impact sprinkler is to loosen the hose faucet where it is hooked up.The power and coverage of the stream will be increased if the faucet is opened to increase the water flow.If you want to avoid damaging delicate plants, use a lower water flow.
Step 2: The position of the pin needs to be changed.
The base of the sprinkler head has a large screw anchored to it.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.If you want a more concentrated stream, remove the pin all the way.A delicate spray or mist is created when the stream is broken up by the diffuser pin.The spray will be shorter and wider if the pin projects over the opening.
Step 3: The shield should be raised or lowered.
The sprayer head has a flat metal square attached to it.The stream will be diverted into a lower arcs when it hits the shield.Keep the shield up if you are trying to water from one end of the lawn to the other.The stream will be able to travel in a higher arcs.
Step 4: The spray pattern can be changed by using the friction collars.
The movement of the sprinkler head can be determined by twisting the metal clamps that wind around the base.The watering range is narrowed by the closer the collars are.As the sprinkler turns, a metal piece at the base of the head known as the trip pin will run up against the collar, causing it to reverse direction.Make sure the trip pin is within the range you want it to be.It is possible to water the rose bushes outside of your home without using the front porch or garage door.
Step 5: For full coverage, flip up the trip pin.
Lift the trip pin until it rests against the sprinkler head, and you'll be good to go.In a smooth, radial motion, it will be able to send out water.If your sprinkler system is located in the center of the area, getting the trip pin out can be helpful.
Step 6: The distance control dial should be adjusted.
Users can manually set the spray distance on impact sprinkler models.One way to reduce the force of the stream is to turn the sprinkler to the left and the right at the same time.It is easy to get the right coverage if the approximate distances are clearly labeled.If your impact sprinkler doesn't have a distance control dial, you'll get the best spray by tinkering with the water pressure, diffuser pin, and shield.
Step 7: Make sure the water source you use has a pressure of at least 15 psi.
The force needed to make an impact sprinkler system effective won't come from lower water pressures.You may be better off with a different method of irrigation if your sprinklers are falling short or don't seem to be putting out water at a high rate.You can find out how much water you need by calling your local water provider or using a pressure gauge that fits over the end of a garden hose.The average water pressure in most residential areas is between 40 and 60 psi.If you get your water from a pump or well, yours might be lower.
Step 8: The right sprinkler head is what you should choose.
Plastic and metal are used in impact sprinkler heads.Plastic heads are light and easy to turn with a conservative water flow.The metal heads are better able to handle higher pressures than the cheaper ones.Metal sprinkler heads are more durable and will last longer.If you don't know which type of head will work best for your home, consult with a home improvement or gardening expert while you shop for an impact sprinkler system.
Step 9: It's a good idea to clean your sprinkler occasionally.
A new sprinkler may need a good cleaning after it stopped performing.Remove the sprinkler head from the base and disassemble it to get access to the nozzles.Rub each piece with hot water and a bottle brush to remove any debris that may be preventing the sprinkler from moving.A weak stream with normal water pressure, turning to one side and stopping are some of the symptoms of a dirty sprinkler.A mixture of warm water and vinegar can cut through the heavy mineral deposits inside the sprinkler head.
