What height should a sprinkler head be set at?
The correct height for a sprinkler head is to have the top of sprinkler head just above the soil surface. No more than a quarter of an inch above the ground level. This lowers the tripping hazard, and a lawn mower can go past it without causing any damage.
How do you program a sprinkler head?
Impact Sprinkler Head Adjustment All you have to do is rotate the head to increase or decrease the arc. Turn the head clockwise to increase the arc or counterclockwise if you want to reduce the arc. Use an adjustment ring (pictured below) to get a better grip on the nozzle.
How do you adjust a spray head?
To adjust a stationary sprinkler head, find the spray radius adjustment screw on top of the nozzle. You may need to adjust it slightly to point the water spray in the direction of your lawn that you want it. Turning it clockwise can also help lower the water pressure on a spray head that is shooting too much water out.
How do you change sprinkler angles?
Turn off the water, lift the gear-driven pop-up sprinkler out of the ground and rotate the head clockwise as far as it will go. Turn the adjustment screw on the sprinkler head counterclockwise as far as it will go with a flat-head screwdriver. This zeros the spray pattern.
What is the maximum height of sprinkler head?
The maximum ceiling height shall be 40 ft. The minimum operating pressure shall be either 30 psi or 60 psi based upon the applicable storage and ceiling height for the installation as follows: 30 psi for storage heights up to 25 ft.
How Low Should sprinklers be?
Basic Depth Requirements In most areas, burying the pipes 8 to 12 inches below the surface is adequate. This measurement is from the top of the pipe to the surface of the soil, which means your trenches must be slightly deeper to accommodate the pipes.
Should I flush sprinkler head ground?
If the old riser fitting came out with the old head, remove it and screw it onto the new head. Then test-fit the new head by screwing it into the water line. The top of the head should be flush with the ground, not sticking up into the grass.
How do I make my sprinkler spray further?
Using a wrench or a screwdriver, rotate the screw – clockwise to increase distance and counter-clockwise to decrease distance. While turning the adjustment screw, be sure to do so in small increments until you reach your desired distance.
How do you adjust a Rainbird spray?
If you have a Rain Bird sprinkler model that has an adjustable head (the 18/15/12 AP series), you can use your fingers to twist the collar. It can be adjusted from 0-360 degrees.

How do you rotate a sprinkler system?
Sprinkler Adjustment Steps Turn off the water and lift the sprinkler tube out of the ground with pliers. Look for a marker or marks on the edge of the nozzle. Rotate until the mark is aligned with the correct angle to cover your yard. Turn the entire sprinkler until the angle is corrected.
What is the range of a sprinkler head?
With an average throw around 45 feet, an impact sprinkler head is ideal for larger open spaces.
How far can sprinkler heads spray?
For example, an upright sprinkler in an ordinary hazard environment can be as far as 15 feet from an adjacent head. That same head can be up to half that distance—as far as 7.5 feet—from a wall.
How far can a sprinkler head be off a wall?
Sprinkler heads must be a maximum of 12-15 feet apart, depending on the hazard rating of the space (it ranges from Light Hazard to Extra Hazard 1&2), and at least half that distance from the nearest walls (typically 7.5 feet away).
How is sprinkler height measured?
The size of a sprinkler is determined by the height of the stem – the part that pops up. The part that stays in the ground is called a canister and should NOT be measured to determine size. Do NOT measure the entire sprinkler, either, meaning the canister and the pop-up.
How deep should a sprinkler trench be?
Dig for Your Sprinkler System The trenches will be relatively shallow, usually 6 to 12 inches deep, depending on your area’s freeze cycles and frost severity. The trench must also be deep enough to allow the sprinklers to retract underground to prevent breakage from lawn machines.
Should irrigation valves be buried?
Valves can be grouped together in manifolds, or installed individually – and valves should always be buried inside a plastic irrigation valve box. Never bury a valve directly in the dirt.
Do I need to turn off water to replace sprinkler head?
Turn Off Water System – Before beginning your installation it is so important to make sure that your water system is shut off properly. If you don’t get your water shut off before the installation process you will have water spraying everywhere.
Why is my sprinkler head not rotating?
The most common reason for a sprinkler to stop rotating is the accumulation of debris in the filter. When in operation, water turns a small turbine in the base of the sprinkler, which drives a series of gears that cause the head to rotate. The Hunter gear drive mechanism is sealed from dirt and debris.
How do you adjust Rainbird sprinklers?
How do I make my sprinkler head pop up higher?
Press the pop-up riser on the sprinkler head down firmly, but gently, with your foot so that it is pushed all the way back down into the body (you may get wet doing this!) Then release it so it pops back up.
What are sprinkler risers?
Fire sprinkler riser is like a bridge between your water supply and the sprinkler pipes in your building. That’s where water gets onto the building for fire extinguishing purposes. In actual sense, sprinkler riser is the main component of the sprinkler system.
How do you fix a sprinkler head that does not rotate?
How to Do It Disassemble the sprinkler head. Take off the filter at the bottom of the head. Rinse the filter in a bucket filled with clean water to wash out debris. If this doesn’t work you’ll need to have the sprinkler head replaced. If it does work, make sure the head is properly adjusted when you re-install it.
