The 5 Steps To Repairing Faulty Sprinkler Spray

Sprinklers that aren't spraying properly can result in dead spots in the lawn. Examples of faulty spray include inconsistent flow, spraying in the wrong direction, spraying weakly, or failing to spray at all. 

1. Test for Issues

Repairs can't proceed until the location of the exact problem is identified. This is done by running each sprinkler zone individually and checking the heads to see which ones are malfunctioning. Landscape flags are then placed next to any sprinkler head that is spraying weakly, failing to pop up, or spraying unevenly or out of alignment. The flags allow the problem heads to be found easily once the water is shut off.

2. Clean the Heads

Sometimes the simplest repair is to simply clean out the sprinkler valve heads. Dirt, grass, and other debris can get lodged in the spray openings. This obstructs the flow of water so it may not spray out properly. The heads can be removed and rinsed out, and dirt can be poked out with a toothpick. After cleaning, the heads are replaced, re-aligned, and tested to make sure they are working well.

3. Replace the Valve

If cleaning fails or if the valve heads are badly clogged with dirt, then it's time to replace the heads. Fortunately, sprinkler heads aren't very expensive or difficult to replace. Just make sure that the style of the new sprinkler heads matches the old one. New heads will need to be properly aligned to ensure that the spray is properly covering the lawn area targeted by the sprinkler. 

4. Repair the Line

A broken line often has other issues beyond weak or non-existent spray from the sprinkler heads. You may notice a soggy area on the lawn, which will be near where the line leak is located. If you aren't sure where the possible leak may be, it is likely along the stretch of line just ahead of the first sprinkler in the zone that is malfunctioning. The line must be dug up and replaced with a new length that doesn't have any damage.

5. Verify the Pressure

Pressure issues can be spotted easily — the first few sprinkler heads will likely spray with more force, and then the force will gradually reduce as you move further down the line. In some cases, the pressure fluctuates, which causes the force of the spray from the heads to fluctuate. Pressure issues can be fixed by replacing the pressure regulator on the line.

About Me

New Landscape Makes a Yard Feel New Again

Hi. My name is Martha. My husband Leo and I are empty nesters. The last of our three kids moved out of the home about eight years ago. Since that time, we have talked a great deal about retirement and what we wanted to do with our house. The house is slightly too large for just the two of us, but we already have two grandchildren and from the way our kids talk, we are in for plenty more. We have decided to stay in our home since it has plenty of room for our family to come and stay with us from time to time. The one thing we really wanted to change is the backyard. Leo retired last year, and I’ll be retiring in about six months. We are already talking with the landscape contractor, and I’m excited to share some of our plans with you!
