Keep Your Treasure Valley Lawn Green, Not Drowned
In Meridian and across the Treasure Valley, a healthy, vibrant lawn is a point of pride for any homeowner. Our hot, dry summers make an efficient sprinkler system not just a convenience, but a necessity. But what happens when that system stops working correctly? A malfunctioning sprinkler can lead to frustrating brown patches, swampy areas, wasted water, and surprisingly high utility bills. Knowing how to spot the signs of trouble can save you time, money, and your lawn’s health.
Whether it’s a sputtering head, a persistent leak, or uneven coverage, sprinkler problems rarely fix themselves. This guide will walk you through the most common sprinkler issues we see in the Meridian area and provide practical steps for diagnosis. For reliable, expert solutions, the local team at Barefoot Lawns has the experience to get your irrigation system running perfectly.
Common Sprinkler Problems and How to Address Them
An irrigation system has many moving parts. Over time, wear and tear, soil shifting, and the dramatic Idaho weather can take their toll. Here are some of the most frequent issues homeowners face.
1. Clogged or Dirty Sprinkler Heads
The Symptom: Water sputters out, sprays in an erratic pattern, or doesn’t come out at all from one or more heads.
What’s Happening: This is often the simplest problem to fix. Dirt, small pebbles, or grass clippings can easily get lodged in the sprinkler nozzle or filter screen. Over time, hard water deposits common in our region can also cause blockages.
What You Can Do: Carefully unscrew the sprinkler nozzle. Clean it and the small filter screen inside with a brush and water. If mineral buildup is the culprit, soaking the parts in vinegar can help dissolve it. If cleaning doesn’t solve the issue, the head itself may be damaged and need replacement.
2. Low Water Pressure
The Symptom: The sprinkler heads don’t pop up fully, or the water spray is weak and doesn’t reach its intended distance, leading to dry spots.
What’s Happening: Low pressure can stem from several sources. The most common is a leak in the underground supply line. A cracked pipe, even a small one, can release enough water to significantly drop the pressure for the entire zone. Another cause could be a partially closed backflow preventer valve or a crushed pipe from tree roots or vehicle traffic.
What You Can Do: Check your backflow preventer to ensure both valves are fully open. Walk the lawn between sprinkler heads looking for unusually green or soggy patches, which can indicate an underground leak. Locating and fixing these leaks often requires professional expertise and tools. For persistent pressure issues, a professional sprinkler service is your best bet.
3. Leaking Control Valves
The Symptom: You notice constant wet spots around a single sprinkler head even when the system is off, or water continuously trickles from heads in one zone.
What’s Happening: The control valve is like a faucet for each sprinkler zone. If a valve is leaking, it’s usually because debris is trapped inside, or the internal diaphragm has worn out. This allows water to constantly seep through to the sprinkler heads.
What You Can Do: Identifying and cleaning or rebuilding a valve can be a complex task, often involving shutting off the main water supply and disassembling the valve manifold. Due to the risk of causing more damage, this is a repair best left to experienced technicians.
4. Incorrect Spray Patterns & Coverage
The Symptom: Your lawn has distinct dry, brown patches next to lush, green areas. Water is spraying onto your driveway, fence, or house instead of the grass.
What’s Happening: Sprinkler heads can get knocked out of alignment by mowers or foot traffic. Over time, the ground can settle, changing the angle of the head. Sometimes, the wrong type of nozzle is installed for a specific area, leading to poor coverage.
What You Can Do: You can often adjust the spray direction and arc of rotor and spray heads by hand. However, optimizing an entire system for head-to-head coverage to ensure every inch of your lawn gets watered properly is a science. A professional audit can diagnose these inefficiencies, potentially saving you water and improving lawn health through better lawn aeration and water absorption.
Did You Know? Water Conservation Facts
- A single broken sprinkler head can waste up to 25,000 gallons of water over a six-month watering season.
- A tiny leak in a sprinkler pipe, just 1/16th of an inch in diameter, can waste over 6,000 gallons of water in a single month.
- Proper irrigation promotes deep root growth, making your lawn more resilient to drought and pests like grubs. Our Grub Control services are even more effective with a well-watered lawn.
The Importance of Seasonal Sprinkler Maintenance in Meridian
Idaho’s distinct seasons demand a proactive approach to irrigation. Simply turning your system on in the spring and off in the fall isn’t enough to prevent costly damage.
Spring Start-Up
Turning on your system after a long winter requires more than just flipping a switch. A proper spring start-up involves slowly pressurizing the main line to prevent water hammer, checking every zone for leaks or damage that occurred over winter, cleaning all heads, and setting the controller for efficient watering schedules. This preventative check ensures you start the season right.
Fall Winterization (Blow-Out)
This is arguably the most critical service for any sprinkler system in the Treasure Valley. When temperatures drop below freezing, any water left in the pipes can freeze, expand, and crack pipes, valves, and sprinkler heads. A professional blow-out uses a high-volume air compressor to force every drop of water out of the system, protecting your investment from expensive freeze damage. This is a crucial part of any complete landscape maintenance program.

Frequently Asked Questions (FAQ)
How often should I have my sprinkler system checked?
We recommend a professional inspection at least once a year, ideally during your spring start-up. This allows a technician to catch small issues before they become major, expensive repairs and ensures your system is optimized for the upcoming season.
What are the signs of a hidden underground leak?
Look for unexplained soggy spots in the yard, areas of grass that are much greener than the rest, eroding soil, or a sudden, unexplained increase in your water bill. A constantly running water meter when all faucets are off is another clear indicator.
Is a professional sprinkler blow-out really necessary in Idaho?
Absolutely. The ground in Meridian and Boise freezes every winter. Failing to remove all water from your sprinkler lines is one of the most common and costly mistakes a homeowner can make, often leading to cracked pipes and manifolds that require extensive digging and repair.
Can you also help with pest problems found during sprinkler checks?
Yes. A healthy, properly watered lawn is less susceptible to pests. If we notice signs of insect damage during a visit, we can recommend our effective, family-safe pest control solutions to protect your yard.
