How to Find Sprinkler Heads Covered by Grass: 7 Easy Methods
It’s time for a search and rescue
Dirt, grass, and overgrown landscaping can bury your sprinkler heads over time. Your lawn and plants won't get enough water if you have a sprinkler head that’s gone missing. You might even experience flooding or uneven watering across your yard, killing off your plants and making your property look sloppy. Luckily, there are a few ways to find buried sprinkler heads to help keep your yard in pristine condition. Learn all about how to find sprinkler heads covered by grass and plants.
Why Find Missing Sprinkler Heads?
A well-working sprinkler system keeps your lawn lush, green, and healthy. If a sprinkler head is missing, it can lead to flooding, fungi growth, uneven watering, brown blades, and dormant grass. Finding a missing sprinkler head can save you money on your water bill and time caring for your lawn in the long run.
How Much Does a Sprinkler System Inspection Cost?
An average sprinkler system inspection costs $50 to $100 per hour. Beyond finding buried sprinkler heads, a pro can ensure your system has even water pressure and works optimally to save on your water bill.
Signs of a Buried Sprinkler Head
You may have a buried sprinkler head if you notice:
Flooding in a particular area of your yard
Uneven watering across your yard
A dry or brown patch on your lawn
A zone in your yard that seems like it should have a sprinkler head but doesn’t
Higher than usual water bills when your sprinkler system is running
Uneven or low water pressure across sprinkler heads
Sprinkler zones that won't turn on
How to Find Sprinkler Heads Covered by Grass
You can find sprinkler heads in a few ways without digging up large portions of your lawn. Try these methods to find buried sprinkler heads.
Look and Listen for Pooling Water
Cap your sprinkler heads or switch off the valves that lead to the known heads. Turn on your sprinkler system and wait 20 to 30 minutes to allow a substantial amount of water to run, then turn the system off.
Walk around your yard and look for areas that pool with water, or use a soil moisture probe to find oversaturated spots. You can also listen for the sound of rushing or trickling water underground. The sound can lead you to where water might be streaming from a missing head.
Mark any areas that you suspect might have a buried head. Insert sticks or flags into the ground to help narrow in where the missing head might be.
Consult Your Irrigation System Map
Most sprinkler systems come with a system map or diagram that shows the location of each sprinkler head and supply line. Look at your system map to identify the existing sprinkler heads. It may be helpful to put flags or sticks near the current heads. Looking at the map and your lawn with the current heads, try to locate where the missing heads likely are.
Measure the Distance Between Two Active Sprinkler Heads
Measure and write down the distance between two active heads with a tape measure. Measure the distance on a few sets of heads to determine if there is an average. The average distance can give you an idea of how far apart the heads are, helping you estimate where a buried sprinkler head might be. In most cases, sprinkler heads are evenly placed in a pattern on your property. Knowing the pattern and distance can help you identify where missing heads are.
This method can be more challenging if you have an extensive irrigation system with custom zoning. You might be better off hiring a pro or using a metal detector.
Look at Grass Growth and Health
When sprinkler heads are missing, the surrounding section of grass won't receive the water it needs. Notice areas with dry, brown, or wilting grass and plants on your property. A missing sprinkler head is likely nearby. You can also look for areas with a mix of green and dormant or dead grass. The sprinkler head might be partially blocked and only watering some of the soil.
Pull a Garden Rake Across Your Lawn
If a sprinkler head is buried near the surface, a garden rake can help you locate it. Hold a garden rake against the lawn, dragging the rake slowly across the surface. Try not to drag the rake too deep as it can damage your grass.
If you’ve narrowed down the area you believe the missing head is in, this method can be particularly helpful. You will feel or hear when the rake hits a sprinkler head. Mark the location with a flag or stick.
Use Metal Detector
Running a metal detector across your yard is a simple way to find a sprinkler head. If you hire a professional to help find sprinkler heads covered by grass, they’ll likely use metal detectors as almost all sprinkler heads contain metal. Using a metal detector to find a sprinkler head is quicker if you've limited the area you need to search. Consider using the other methods in this guide to narrow down the area first and save time.
You may need to adjust the sensitivity settings on your metal detector by putting it over one of your known heads. You want to ensure the device detects other heads. As you go, mark each possible sprinkler head location with a flag or stick.
Contact a Sprinkler System Pro
No matter your method, it can be hard to find buried sprinkler heads, especially if you're moving into a new house and are unfamiliar with the landscaping. Contact a local sprinkler installer to locate the sprinkler head and dig it out. You can save time by hiring a pro, allowing you to fix the issue and get your lawn up and green again sooner.
Tips for Maintaining Your Sprinkler System
Keep your irrigation system in great shape and working properly by following these expert maintenance tips.
Create a map of your irrigation system or take photos for future reference to ensure you can find all your sprinkler heads in consecutive years.
Clean your sprinkler heads once per year, ideally in the spring.
Install smart technology or a rain sensor to prevent oversaturation.
Check your sprinkler system once a month for clogged or leaking sprinkler heads. Unclog any sprinkler heads with a small piece of flexible wiring.
Repair or replace sprinkler heads and parts when you notice leaks and other issues.
Watch for areas of your lawn that are overwatered and adjust your system.
Monitor the system’s water pressure and use a water pressure regulator or booster pump to restore even watering.
Winterize your sprinkler system every fall if you live in a climate that experiences freezing temperatures.
DIY vs. Hiring a Pro
You can find most missing sprinkler heads yourself with the right tools and enough time. But it can be tricky and time-consuming, especially if you have a large yard or custom zoning. Consider hiring a local sprinkler installer to identify buried sprinkler heads, dig them up, and optimize your system for the season.
Sprinkler system repair work costs between $50 and $100 per hour on average. The investment is well worth it, especially if you can increase your lawn’s health and save on water bills.
Frequently Asked Questions
You can find a sprinkler head without digging by using a metal detector. Because most sprinkler heads contain metal, a metal detector can identify heads buried by grass, dirt, or plants. Narrow your search area by looking at your sprinkler system map or by turning on the water, watching for flooding areas, and listening for water trickling underground. Mark areas with possible missing sprinkler heads with flags or sticks, then use your metal detector in those spots.
Yes, you can find sprinkler heads with a metal detector. Run the metal detector over a known sprinkler head, then adjust your device’s sensitivity settings so that it can detect other heads easily. Run the metal detector over any areas where you believe a missing head could be and pin the missing head with a flag or stick.
