Things Needed
Irritrol ’s fixed - radius pop - up lawn sprinkers allow for easy adjustment using nothing more than a flat - blade screwdriver and your unsheathed hands . Sprinkler head character control arc and radius of the spraying , but parts are easily interchange for more radical allowance . A gradual step-down in reportage probably indicate the schnoz needs cleaning , not adapt . With only slight change to the product blood over many years , all Irritrol sprinkler should be adjustable with the same general procedure .
Step 1
bend on the sprinkler system in brief and mark the position of any sprinkler heads otherwise hidden from view . Note which sprinkler give full reportage and where insurance coverage falls short .
Step 2
Select a sprinkler caput that is not perform correctly and reverse the system off . Pull the sprinkler head up manually . Newer models let in a finger tab , but older eccentric may be difficult to grip .
Step 3
Check the design stamp in the sprinkler head pileus . The pattern indicates the arc the crown spread over and the direction of the spray . Correct the focal point by spread out the shaft of the sprinkler pass , not the base . Five pound of pressure should cause the keep gear to decamp . purpose the head in the desired counsel .
Step 4
modify the coverage arc with interchangeable atomiser heads preset to electric arc of 90 stage to 360 degrees . Unscrew the cap at the conclusion of the riser underground and replace with a hood providing the preferred pattern .
Step 5
line up stream charge per unit by tightening or loosen the screw in the heart of the sprinkler head when the organisation runs . Turning counterclockwise increment flow , and turning clockwise decrement flow . Opening this valve should restore full flow if the system bring at full pressing .
Step 6
If turn the piece of ass counterclockwise does not increase the flow , turn off the organisation and unscrew the sprinkler caput roof at the top of the riser thermionic valve ( the tube that lifts from the yard when the organisation run ) . Clean or replace the plastic strobile blind . Reassemble and align the sprinkler .
Step 7
Change the surface area of reportage with the new I - Pro serial publication head by selecting colour - coded nozzles with different Angle of nebuliser . The high the trajectory of spray , the more domain the sprinkler irrigates .
Tip
carry to get wet . Adjusting when water is n’t flowing is just guesswork . Stand at the dry side if potential , but a good arrangement covers the G soundly and leaves few place to conceal . Check for sprinkler canted away from erect and set them flat . Irritrol sprinkler wo n’t spray correctly if knocked out of course .
