Why Is My Sprinkler Head Spraying Sideways?

Quick Answer

A sprinkler head that sprays sideways is usually caused by a clogged or damaged nozzle, an improperly adjusted spray pattern, a cracked sprinkler head, low water pressure, or physical damage from lawn equipment. In some cases, the sprinkler itself isn’t the problem—low pressure or a partially clogged irrigation system can cause the spray pattern to become distorted.

Before replacing the sprinkler head, inspect the nozzle and determine whether only one sprinkler or the entire irrigation zone is affected.

Signs Your Sprinkler Head Is Spraying Sideways

You may notice:

  • Water spraying onto the sidewalk or driveway
  • A fan-shaped spray pointing in the wrong direction
  • Uneven watering around the sprinkler
  • Water shooting from the side of the sprinkler body
  • Reduced coverage in the intended watering area

These symptoms can waste water and leave parts of your lawn under-watered.

Why Sprinkler Heads Spray Sideways

Sprinkler heads are designed to distribute water in a controlled pattern. When the nozzle, body, or internal components become damaged or obstructed, the water is forced in unintended directions.

Sometimes the problem is as simple as a nozzle that has been bumped out of alignment. Other times it indicates internal damage or pressure problems elsewhere in the irrigation system.

Common Causes

Clogged Nozzle

Dirt, sand, grass clippings, or mineral deposits can partially block the nozzle opening.

Instead of producing a uniform spray pattern, water exits unevenly and may shoot sideways.

Signs include:

  • Weak coverage
  • Uneven fan pattern
  • Water spraying at unusual angles

Cleaning the nozzle often restores normal operation.

Damaged Nozzle

A cracked or chipped nozzle changes the direction of water flow.

Common causes include:

  • Lawn mower impact
  • Weed trimmers
  • Age
  • Freezing temperatures in colder climates

Replacing the nozzle is usually inexpensive and often solves the problem.

Incorrect Spray Pattern Adjustment

Many spray heads allow the watering arc to be adjusted.

If the adjustment has been changed accidentally, the sprinkler may appear to spray sideways even though it’s operating normally.

Verify that the spray pattern matches the area being watered.

Low Water Pressure

Low pressure can cause the spray pattern to collapse or become distorted.

Possible causes include:

  • Underground pipe leaks
  • Irrigation valve problems
  • Too many sprinkler heads on one zone
  • Pump problems

If several sprinkler heads have poor spray patterns, investigate the irrigation system before replacing individual heads.

Cracked Sprinkler Head

Cracks in the sprinkler body allow water to escape before reaching the nozzle.

Instead of producing a controlled spray, water may shoot from the side of the head or around the riser.

Replacement is usually the best solution.

How to Diagnose the Problem

Ask yourself:

Is only one sprinkler spraying sideways?

If yes, inspect the nozzle and sprinkler head.

Are multiple sprinklers spraying sideways?

This usually indicates a pressure or system-wide problem.

Is water coming from the nozzle or the side of the sprinkler body?

  • From the nozzle → Clean or replace the nozzle.
  • From the body → Inspect for cracks or damage.

Has the sprinkler been hit recently?

Damage from lawn equipment is one of the most common causes of sideways spray.

Can You Fix It Yourself?

Most homeowners can repair a sprinkler spraying sideways by:

  • Cleaning the nozzle
  • Replacing the nozzle
  • Adjusting the spray pattern
  • Replacing a damaged sprinkler head

If multiple sprinklers are affected, inspect the irrigation valve and water pressure before replacing components.

Frequently Asked Questions

Why is my sprinkler spraying the sidewalk?

The nozzle may be clogged, damaged, or incorrectly adjusted. The sprinkler itself may also have been rotated or moved.

Can low pressure make a sprinkler spray sideways?

Yes. Low pressure can distort the spray pattern and reduce the distance water travels.

Should I replace the whole sprinkler head?

Not always. Many problems are caused by the nozzle, which is inexpensive and easy to replace.

Why did my sprinkler suddenly start spraying sideways?

The most common causes are debris inside the nozzle, accidental impact from lawn equipment, or a damaged sprinkler head.
