4 Common Sprinkler Problems in White Settlement

A healthy, green lawn is a point of pride for any White Settlement homeowner, and your sprinkler system is your best ally in keeping it that way, especially during the intense North Texas summers. But what happens when that reliable system starts to fail? A malfunctioning sprinkler can quickly lead to brown patches, wasted water, and high utility bills. At Mr. Sprinkler Repair, we’ve seen it all, and we’re here to help you get your lawn back on track.

At Mr. Sprinkler Repair in White Settlement, we believe that understanding the common issues affecting local irrigation systems is the first step toward a quick solution. From sudden cold snaps to the challenges of our clay soil, your sprinklers face unique pressures. This guide will walk you through four frequent sprinkler problems we see, helping you identify the signs, perform simple checks, and know when it’s time to call in the professionals.

1. Sensor Malfunctions are Disrupting Your Schedule

Have you noticed your sprinklers running in the middle of a downpour? Or perhaps they aren’t turning on at all, even when the lawn is bone-dry. The problem might be a faulty rain or moisture sensor. These small devices are designed to make your system smarter by automatically adjusting the watering schedule based on recent rainfall, saving water and preventing over-saturation.

Symptoms of a Sensor Problem

Watering in the Rain: This is the most obvious sign. A working rain sensor should shut the system off when it detects sufficient moisture.
System Never Turns On: If a sensor is stuck in the “wet” mode or has a wiring issue, it can prevent your scheduled watering cycles from ever starting.
Inconsistent Watering: The system might work sometimes but not others, suggesting an intermittent connection or failing sensor component.

What Causes Sensor Failure?

Sensors live outdoors, exposed to everything North Texas weather throws at them. Common causes of failure include:

Debris like leaves, twigs, or dirt clogging the sensor.
Pest or insect damage.
Frayed or disconnected wires.
Simple old age—the internal components can wear out over time.

Quick DIY Checks

Before calling for service, you can try a few things. First, visually inspect the sensor. It’s usually a small device mounted on a fence, eave, or near your controller box. Clear away any visible debris. Check that the wires are securely connected to your controller’s “SEN” or “SENSOR” terminals. You can also consult your system’s manual to learn how to bypass the sensor temporarily. If the system works when bypassed, you’ve found your culprit.

When to Call a Pro

If a simple cleaning and wire check doesn’t solve the issue, it’s time to call for help. A professional technician can accurately diagnose whether it’s a wiring short, a bad sensor that needs replacement, or an issue with the controller itself. We can ensure the right sensor is installed and calibrated for White Settlement’s weather patterns.

2. Incorrect Nozzle Types are Wasting Water

Not all sprinkler heads are created equal, and using the wrong nozzle can have a big impact on your lawn’s health and your water bill. Different areas of your yard have different needs. A spray head is great for small, narrow strips of grass, while a rotor head is better for large, open areas. Mismatched nozzles can lead to overwatering some spots and completely missing others.

Signs of Mismatched Nozzles

Dry, Brown Patches: Areas of your lawn look perpetually thirsty, even after the sprinklers have run.
Water Running onto Sidewalks: This indicates the spray pattern is wrong for the shape of the zone.
Misty Spray (Fogging): If the water pressure is too high for the nozzle type, water vaporizes before it hits the ground, leading to evaporation and waste.
Puddles and Soggy Spots: This suggests too much water is being applied too quickly, which is a common problem in our dense clay soil.

Why Does This Happen?

Often, incorrect nozzles are the result of a previous DIY repair or an initial installation that didn’t account for the specific needs of each zone. The landscape may have also changed over time—a new flower bed or patio can render the original nozzle setup inefficient.

Quick DIY Checks

Walk your property while the sprinklers are running (one zone at a time). Do you see an even distribution of water? Are spray heads watering a large lawn area that would be better served by a rotor? Are delicate flower beds getting blasted by a high-pressure stream? You can buy different nozzles at a hardware store, but be sure to match the brand and threading of your existing sprinkler heads.

When to Call a Pro

Choosing the right nozzle involves understanding flow rates, precipitation rates, and pressure. It’s more complex than it sounds. If your attempts at fixing things lead to more dry spots or runoff, a professional assessment is your best bet. An expert from Mr. Sprinkler Repair can perform a full efficiency audit, ensuring every zone in your White Settlement yard has the perfect nozzle for optimal coverage and water conservation.

3. Frozen and Damaged Pipes from Winter Cold Snaps

We may not have long, snowy winters, but North Texas is known for its sudden, hard freezes. When water inside your sprinkler pipes freezes, it expands, putting immense pressure on the PVC. This can lead to cracks, splits, or burst pipes that you might not discover until you turn the system on in the spring.

Symptoms of Freeze Damage

Geysers or Spouts of Water: A dramatic spray of water from the ground is a clear sign of a broken lateral line.
Puddles or Sinkholes: Water pooling in your yard or soft, mushy spots can indicate a slow leak underground.
Low Water Pressure: If one or more zones seem weak, a crack in the pipe could be letting water escape before it reaches the heads.
A Zone That Won’t Turn On: A major break can cause the zone to lose all pressure, resulting in no water at the heads.

Why Winter is So Tough on Sprinklers

The main culprit is water left in the lines when temperatures plummet below 32°F. Even a properly drained system can retain small amounts of water in low spots. The backflow preventer is particularly vulnerable to freeze damage if not properly insulated or drained.

Quick DIY Checks

The best “check” is preventative. Before the first freeze, make sure your system is properly winterized. This involves shutting off the water supply and draining the lines. After a freeze, your first run of the season is your diagnostic test. Walk the property as each zone runs and look for the symptoms listed above. If you spot a leak, shut off the water to your irrigation system immediately to prevent flooding and water waste.

When to Call a Pro

Pipe repairs, especially underground ones, require excavation and precise PVC plumbing work. It’s a dirty job that’s best left to professionals. A technician can quickly locate the leak, repair the broken section of pipe, and check the rest of the system for any other potential damage. We can also ensure your system is properly winterized next fall to prevent future issues.

4. Sprinkler Heads That Won’t Rotate

Rotor heads are designed to turn slowly, casting water over a large arc. When one stops rotating, it concentrates all the water in a single direction. This creates one very soggy, overwatered spot and a large, dry arc that quickly turns brown.

Symptoms of a Stuck Rotor

A Perfect Circle of Green Grass: You’ll see a lush, green patch of lawn right where the sprinkler is stuck.
A Fan-Shaped Brown Patch: The area the rotor is supposed to be watering will be dry and wilted.
The Head Pops Up But Doesn’t Turn: You can see the sprinkler is active, but the turret isn’t moving.

What Causes Rotors to Stick?

Debris: Dirt, sand, or small pebbles can get inside the gear mechanism and jam it.
Low Water Pressure: The rotor may not have enough force to turn if there’s a leak elsewhere in the zone or the main valve isn’t fully open.
Internal Wear and Tear: The plastic gears inside the rotor can strip or break down over time.
Damage: Lawn mowers and edgers are the natural enemies of sprinkler heads and can easily damage the casing or turret.

Quick DIY Checks

First, try to gently turn the rotor head by hand (with the system off). Does it move freely, or is it stuck? Check the base of the head for dirt or grass that might be blocking it. You can also try cleaning it. Unscrew the top cap and lift out the internal assembly. Rinse it under clean water to flush out any debris before reinstalling.

When to Call a Pro

If cleaning doesn’t work, the internal gear drive is likely broken. While you can buy a replacement head at a big-box store, ensuring you get the exact model and nozzle to match the others in the zone is crucial for maintaining even precipitation rates. A professional can quickly replace the faulty head, adjust the arc and spray distance, and check the zone’s pressure to make sure that wasn’t the underlying cause of the failure.
