Identifying and addressing common sprinkler issues to keep your Treasure Valley lawn green and healthy.
A lush, vibrant lawn is the pride of any homeowner in Caldwell, Boise, or anywhere in the Treasure Valley. Given our hot, dry summers, a reliable sprinkler system isn’t a luxury—it’s a necessity for maintaining a healthy landscape. But what happens when you notice dry, brown patches, soggy spots, or a sudden spike in your water bill? These are often the first signs that your Boise lawn irrigation system needs attention. Ignoring these issues can lead to wasted water, damaged turf, and costly repairs down the road. This guide will walk you through the most common sprinkler problems and help you decide when a quick fix is possible and when it’s time to call in the professionals.
Common Sprinkler Problems and Their Solutions
1. Clogged or Dirty Sprinkler Heads
The Symptom: The sprinkler head doesn’t pop up, sprays erratically, or water just bubbles out from the base. Dry patches in your lawn can also indicate a clogged nozzle is preventing proper water distribution.
The Cause: Dirt, sand, and other debris can easily get lodged in the small filter or nozzle of the sprinkler head after lawn maintenance or due to shifts in the soil.
DIY Check: For many pop-up heads, you can unscrew the top nozzle, lift out the filter basket, and rinse them both with clean water. Use a small wire to gently clear any persistent debris from the nozzle opening before reassembling.
2. Broken or Damaged Sprinkler Heads
The Symptom: You might see a geyser of water shooting into the air or a head that is visibly cracked or crushed. This is a frequent issue, often caused by lawnmowers, foot traffic, or vehicles.
What to do: Replacing a sprinkler head is often a manageable task. After turning off the water, you’ll need to dig around the broken head, unscrew it from the riser pipe, and screw on a new, compatible head. However, if the riser pipe below is also damaged, the repair becomes more complex.
3. Low Water Pressure
The Symptom: The sprinkler heads mist water instead of spraying, or they don’t pop up all the way. Water may just dribble out, leading to poor coverage.
The Cause: Low pressure can stem from several issues, including a partially closed backflow valve, a leak in the mainline pipe, or even tree roots crimping the line underground. It could also be a system design issue where too many heads are on a single zone.
Professional Help Needed: Diagnosing the root cause of low pressure can be tricky. Professionals have the tools to check for hidden underground leaks and assess the system’s design, ensuring an effective and lasting solution.
4. Leaking Control Valves
The Symptom: A specific zone won’t turn off, or you notice constant puddling and sogginess around the valve box, even when the system is off. This leads to significant water waste.
The Cause: A worn-out diaphragm or solenoid inside the valve is usually the culprit. Debris can also get trapped inside, preventing it from sealing completely.
When to Call an Expert: While some valve components can be replaced, working with valve manifolds can be complicated. For reliable sprinkler repair in Boise, it’s best to have a technician from Barefoot Lawns diagnose and repair the valve correctly.

The Importance of Seasonal Maintenance in Caldwell & Boise
The Treasure Valley’s climate demands seasonal attention for your irrigation system. Proper spring start-ups and fall winterizations are crucial for longevity and performance.
Spring Start-Up
Turning your system on after a long winter requires more than just flipping a switch. A professional start-up service includes slowly pressurizing the main line to prevent damage, checking each zone, adjusting head spray patterns for optimal coverage, and setting the controller for spring watering schedules. This ensures your lawn gets what it needs from day one.
Fall Winterization (Sprinkler Blow-Out)
In Idaho, winterization is non-negotiable. Freezing temperatures can cause leftover water in your pipes to expand and burst, leading to catastrophic damage. A professional sprinkler blow-out uses a high-volume air compressor to force all water from the pipes, heads, and valves, safeguarding your system against the harsh Idaho winter. Attempting this without the right equipment can result in an incomplete blow-out or damage to your system components.
Did You Know?
A single broken sprinkler head can waste over 6,000 gallons of water in a single month. That’s not just bad for the environment—it’s a significant hit to your wallet. Regular inspection as part of a comprehensive Boise landscape maintenance plan can catch these issues early.

Frequently Asked Questions
How often should my sprinkler system be inspected?
It’s best practice to have your system professionally inspected at least once a year, ideally during the spring start-up. A quick visual check by a homeowner every few weeks during the watering season can also help spot obvious problems like broken heads early.
What are the signs of a hidden underground sprinkler leak?
Look for unexplained wet or soggy spots in the lawn, areas that are unusually green and lush compared to the rest, low water pressure across a zone, or a sudden, unexplained increase in your water bill. You might also notice bubbling water coming from the ground when a zone is active.
When should I schedule a sprinkler blow-out in the Treasure Valley?
Typically, sprinkler winterization in our region should be completed by late October or early November, before the first hard freeze sets in. It’s wise to get on a professional’s schedule early, as demand is high during this time.
Can my sprinkler system also water my trees?
While lawn sprinklers can provide some water, trees have different needs. Deep, infrequent watering is best for root health. Barefoot Lawns offers specialized Boise tree services, including deep root feedings, to ensure your trees get the proper hydration and nutrients they need to thrive.
