Adjusting Sprinkler Heads – A Quick Guide from Mr. Lee at Lee’s General Landscaping

Landscaping

Hey there, neighbors! Mr. Lee here from Lee’s General Landscaping, your friendly Seattle yard guy. Today, let’s talk about something that often gets overlooked—but can make a big difference in your water bill and plant health: adjusting your sprinkler heads.

Whether you’ve got dry patches on your lawn, puddles forming by your walkway, or your rhododendrons are getting soaked when they shouldn’t be, chances are your sprinkler heads need a little love.

Why You Should Adjust Your Sprinklers

Sprinkler systems aren’t “set it and forget it.” Over time, heads can shift, clog, or start spraying the wrong direction. Around here in Seattle, we see a lot of this due to soft soil, growing plants, or good ol’ seasonal shifting.

A quick adjustment can help you:

  • Save water (and money)
  • Avoid soggy or dry spots
  • Keep plants healthy
  • Prevent water runoff and sidewalk stains

Common Sprinkler Head Issues in Seattle

Here’s what we usually run into when servicing irrigation systems:

1. Heads Spraying Sidewalks or Fences

Wasting water, staining fences, or making your walkway slippery? The angle just needs a little tweak.

2. Mismatched Spray Patterns

Some heads spray a full circle, others a half or a quarter. If the pattern’s off, you’ll get uneven watering.

3. Blocked or Buried Heads

Grass and mulch love to grow over sprinkler heads. You gotta dig ’em out and raise them up sometimes.

4. Low Water Pressure

This one’s tricky—it could be the valve, the line, or the head itself. But start simple by checking the nozzle.

How to Adjust a Sprinkler Head (The Mr. Lee Way)

Alright, here’s a simple method to get things tuned up:

🛠 Tools:

  • Flathead screwdriver or rotor key
  • Garden gloves (optional but handy)
  • A sharp eye

Steps:

  1. Turn on your sprinkler zone (one at a time if possible).
  2. Watch the spray — Is it reaching too far? Not far enough? Hitting the wrong area?
  3. Adjust the angle — Most spray heads have a nozzle you can twist left or right.
  4. Dial in the range — Use your screwdriver to shorten or lengthen the spray distance.
  5. Check overlap — Make sure each head overlaps slightly with the next for full coverage.

Pro Tip from Mr. Lee: Water early in the morning (before 10 a.m.) for best results. Less evaporation, less wind, and your plants will thank you.
