4 Common Sprinkler Issues in Fort Worth (And How to Fix Them)

A healthy, green lawn is a point of pride for any Fort Worth homeowner, but keeping it vibrant through the Texas heat requires a reliable sprinkler system. When your irrigation system fails, it doesn’t just put your landscape at risk—it can also lead to wasted water and higher utility bills. Spotting problems early is key to maintaining a beautiful yard and conserving resources.

This guide will walk you through four of the most common sprinkler system issues we see in the Fort Worth area. We’ll explain the signs of each problem and discuss why professional repairs are often the best solution for your home.

1. Faulty Pressure Regulators and Water Pressure Problems

Have you noticed that some sprinkler heads are misting into the air while others barely spray a few feet? These are classic signs of inconsistent water pressure, often caused by a faulty pressure regulator. This small but vital component ensures that water flows through your system at the correct pounds per square inch (PSI).

Signs of a Pressure Regulator Issue:

• Misting or Fogging: When pressure is too high, water atomizes into a fine mist that evaporates quickly or gets carried away by the wind. This means very little water actually reaches your lawn’s roots.
• Low Water Pressure: If the pressure is too low, sprinkler heads won’t pop up fully or will only produce a weak stream, leading to dry, brown patches across your yard.
• Uneven Coverage: You might see overly saturated spots near some sprinkler heads and completely dry areas elsewhere.
• Damaged Sprinkler Heads: Consistently high pressure can damage the internal seals and gears of your sprinkler heads, causing them to leak or break prematurely.

A properly functioning regulator protects every component in your system from excessive wear and tear. It also ensures each zone of your lawn receives the precise amount of water it needs to thrive. Replacing or adjusting a pressure regulator requires specialized tools and knowledge of your system’s specifications, making it a job best left to professionals.

2. Electrical Short Circuits and System Malfunctions

Modern sprinkler systems rely on a network of low-voltage wires to communicate between the controller, valves, and sensors. When these wires are damaged, it can cause frustrating and seemingly random malfunctions. Electrical shorts are a frequent culprit, often caused by digging, landscaping activities, rodent damage, or simple degradation over time.

Telltale Signs of an Electrical Short:

• A Single Zone Won’t Turn On: If one specific valve fails to open, it could be due to a cut or disconnected wire leading to that zone.
• Multiple Zones Running at Once: A short circuit can cause several valves to open simultaneously, which drastically lowers water pressure and leads to ineffective watering.
• The System Won’t Turn On at All: A severed common wire or a short at the controller can prevent the entire system from activating.
• Blown Fuses: Your controller may have a fuse that blows repeatedly, indicating an underlying electrical fault that needs to be traced and repaired.

Diagnosing electrical problems requires a multimeter and a systematic approach to trace the wiring from the controller to each valve. Without the right equipment, finding a tiny break or short in a wire buried underground is nearly impossible. An experienced technician can quickly locate the fault and repair it, restoring your system’s reliability.

3. Manual Timer and Controller Issues

Your sprinkler controller, or timer, is the brain of the entire operation. While modern digital controllers are quite reliable, older manual timers or even newer models can develop problems. A malfunctioning controller can disrupt your watering schedule, leading to an overwatered or underwatered lawn.

Common Controller and Timer Problems:

• Inaccurate Clock or Schedule: The timer may lose time or fail to run the programmed watering schedule, often due to a dead backup battery or internal failure.
• Unresponsive Buttons or Dial: You may find that the dial is stuck or that the buttons don’t respond, making it impossible to adjust settings.
• Faded or Blank Display: A blank screen usually points to a power supply issue, a blown fuse, or a completely failed unit.
• Programs Erased Randomly: If your carefully set schedules keep disappearing, the controller’s internal memory could be failing.

Sometimes, a simple reset or a new backup battery can solve the problem. However, if the issues persist, it’s often more cost-effective to upgrade to a modern, “smart” controller. These new devices can adjust watering schedules based on local weather, saving you significant water and money over time.

4. Non-Functional Rain Sensors

A rain sensor is a simple device with a big job: it prevents your sprinkler system from running during or immediately after a rainstorm. When this sensor fails, your system will water your lawn even when it’s already saturated. This not only wastes a tremendous amount of water but can also harm your lawn by promoting fungal growth and shallow root development.

How to Tell if Your Rain Sensor is Broken:

• System Runs While It’s Raining: This is the most obvious sign that your sensor is not communicating with the controller.
• Debris or Damage: The sensor’s hygroscopic discs (which swell when wet) can become clogged with leaves or dirt. The unit itself can also be damaged by falling branches or hail.
• Wiring Issues: Just like other electrical components, the wire connecting the sensor to the controller can be cut or disconnected.

Testing a rain sensor is straightforward for a professional, who can determine if it needs cleaning, rewiring, or complete replacement. Ensuring your rain sensor works is one of the easiest ways to be a responsible water user in North Texas.
