Sprinkler Head

Sprinkler Head

This is the part of your lawn irrigation system that rises up and sprays water. It connects to underground pipes and uses water pressure to push above the grass. You can adjust the nozzle to change how far and how wide the water sprays.

Origin

Sprinkler comes from the Middle English word sprenklen, meaning to scatter drops. The first automated sprinkler systems for lawns were patented in the 1930s.

How you'll see it used

  • The home inspector noted three broken pop up sprinkler heads in the front yard that were leaking water near the driveway.
  • Your monthly water bill suddenly doubled because a lawnmower snapped a sprinkler head and it gushed water for hours.
  • The landscaping quote included 150 dollars to replace four clogged rotor sprinkler heads and adjust the spray patterns away from the house.

What Is a Sprinkler Head?

A sprinkler head is the final piece of your lawn irrigation system. It sits underground when turned off. When your system turns on, water pressure pushes the head up above the grass. Water then sprays out of the nozzle to water your yard. The word sprinkler comes from the Middle English word sprenklen, which means to scatter drops. People have used automated sprinkler systems for lawns since the 1930s. Today, these small plastic or metal parts do the heavy lifting to keep your grass green.

Each head attaches to a network of underground PVC pipes. These pipes connect to your main water supply. You can easily adjust the nozzle on the top of the head. This lets you change how far the water shoots and how wide the spray pattern goes. You want the water to hit your grass, not your driveway or the side of your house.

Types of Sprinkler Heads

Not all yards need the same amount of water. You'll see a few different types of sprinkler heads around your property.

  • Pop up spray heads: These are the most common. They pop up 2 to 4 inches above the ground and spray a constant mist in a fixed pattern. They work best for small or medium lawns.
  • Rotor heads: These pop up and rotate back and forth. They shoot a single, thick stream of water over a long distance. You usually see these in large, open yards.
  • Impact sprinklers: These are the classic metal heads that make a loud ticking sound. They sit above ground or pop up, and they throw water in a strong circle. They handle dirty or hard water very well.

Why They Matter to You

Your sprinkler heads control exactly where your water goes. If they work right, your lawn stays healthy and your water bill stays normal. If they point the wrong way, you waste money watering the street. Bad sprinkler heads can also cause serious problems for your home. If a head sprays directly against your siding or foundation every day, the constant moisture will cause rot or mold.

Common Problems to Watch For

Sprinkler heads live a tough life. They sit in the dirt and face lawnmowers, foot traffic, and freezing weather. You should check them a few times a year. Just walk around your yard while the system runs and look for issues.

  • Broken plastic: Lawnmowers often clip the tops of these heads. A cracked head will gush water in a big puddle instead of spraying a mist.
  • Clogged nozzles: Dirt and grass clippings easily get stuck in the tiny spray nozzle. If a head barely trickles, you probably need to clean the filter inside it.
  • Sunken heads: Over time, the ground settles. A head might sink too low to pop up over the grass. You'll need to dig it up and add a small plastic extension piece to raise it.
Always turn off your irrigation system before you try to unscrew a sprinkler head. If you leave the water on, the pressure will blast dirt and water straight into your face.

What It Costs to Replace

Fixing a sprinkler head is usually cheap and easy. You can buy a replacement head at any hardware store. The parts cost 5 to 30 dollars depending on the brand and style. Digging out the old head and screwing on a new one takes about ten minutes. If you don't want to dig in the mud, you can hire a landscaper. A professional will usually charge 75 to 150 dollars for a service call to replace a few broken heads. Keep in mind that prices vary based on where you live.

Frequently asked

How do I adjust a sprinkler head that sprays the driveway?

Most spray heads have a small screw on the top center of the nozzle. You can turn this screw with a flathead screwdriver to lower the spray distance. You can also grip the base of the pop up stem and twist it to aim the spray away from the concrete.

Why is my sprinkler head leaking water when the system is off?

This usually means the underground valve that controls that zone is failing to close all the way. It allows a slow trickle of water to seep down the pipe and leak out of the lowest sprinkler head in the yard. You'll likely need to clean or replace the zone valve to stop the leak.

Can I mix different brands of sprinkler heads in my yard?

Yes, you can usually mix brands as long as they are the same type of head. You should never put a spray head and a rotor head on the same zone. They put out water at completely different speeds, which will leave parts of your lawn dry and other parts flooded.
