1. Watering at the Wrong Time

Are you running your sprinklers in the middle of a hot, sunny afternoon? If so, a significant portion of that water is likely vanishing into thin air before it ever reaches your lawn’s roots. Watering during peak evaporation times is one of the most common and costly mistakes a homeowner can make. The intense North Texas sun can cause up to 30% of your water to evaporate, reducing your system’s efficiency and leaving your landscape thirsty.

The Best Times to Water in North Texas

To maximize water absorption and minimize waste, the golden rule is to water in the early morning, ideally between 4 a.m. and 10 a.m. During these cooler hours:

Winds are typically calmer, ensuring water lands where it’s intended.
Lower temperatures reduce immediate evaporation.
The water has time to soak deep into the soil before the afternoon heat arrives.

Watering in the evening can seem like a good alternative, but it can leave grass wet overnight, creating a welcoming environment for fungal diseases.

Smart Watering Tips for Royse City Residents

Upgrade to a Smart Controller: Modern “smart” irrigation controllers use local weather data, soil type, and plant information to automatically adjust watering schedules. They know not to run the system after a recent downpour in the area and can adapt to seasonal changes, saving you water and money without you having to lift a finger.
Follow Local Guidelines: Be aware of any local water restrictions in Royse City or Hunt County, which often dictate specific watering days or times. Adhering to these rules helps conserve our community’s resources and avoids potential fines.

If your controller is outdated or you’re unsure how to program it for optimal efficiency, our team can help you upgrade or adjust your settings for perfect, water-wise results.

2. Leaking Sprinkler Valves

A leaking sprinkler valve is a silent wallet-drainer. Valves are the gateways that control the flow of water to each zone of your sprinkler system. When one fails to close completely, it creates a constant, low-level leak that can waste thousands of gallons of water over a season. Because the leak often happens underground, it can go unnoticed for weeks or even months.

Signs of a Leaking Valve

Stay vigilant for these telltale signs:

Soggy Patches: Notice a perpetually wet or marshy spot in your yard, even when the sprinklers haven’t run recently? This often indicates a nearby underground leak.
Unusually High Water Bills: A sudden, unexplained spike in your water bill is a major red flag that water is being lost somewhere on your property.
A Zone That Won’t Shut Off: If you see one sprinkler head or a full zone lightly spraying or dribbling water long after the system has shut down, the corresponding valve is likely stuck open.
Fungus or Mold Growth: Excess moisture from a slow leak can promote mold and fungal growth on your lawn and around the foundation of your home.

Ignoring a valve leak not only wastes water but can also lead to soil erosion, foundation damage, and costly landscape repairs. Fixing a faulty valve usually requires replacing internal components like the diaphragm and solenoid—a job best left to a professional to ensure it’s done correctly.

3. Debris Blocking Spray Patterns

For your lawn to get even hydration, your sprinkler heads need to spray in a clear, consistent pattern. Over time, it’s common for dirt, grass clippings, leaves, and other debris to clog the small nozzles or get trapped in the filter screens. This blockage can disrupt the spray, leading to dry, brown spots in some areas and overwatered patches in others.

How to Check and Clean Your Sprinkler Heads

Conduct a “Catch Can” Test: Place several empty tuna cans or similar containers randomly across a sprinkler zone. Run that zone for 15 minutes. Afterward, measure the water in each can. If you see significant differences in water levels, it’s a sign of poor coverage, likely due to blocked or misaligned heads.
Inspect and Clean Nozzles: If a sprinkler head is misting, sputtering, or spraying in an odd direction, turn off the system and check the nozzle. Often, you can simply wipe away visible debris. For internal clogs, you may need to unscrew the nozzle and rinse it out.
Check the Filter: Most sprinkler heads have a small filter screen located at the base of the nozzle. This is the primary defense against debris. Carefully remove the pop-up sprinkler body, pull out the filter, and rinse it under water to clear any sediment.
Ensure Proper Head Height: Sprinkler heads should sit flush with the soil or slightly above it. If they sink too low, they can easily get clogged by grass and dirt. Our technicians can raise sunken heads to the proper height.

Regularly trimming the grass around your sprinkler heads can also help prevent them from becoming obstructed.

4. Mowing Damage

Lawn mowers and line trimmers are the top culprits behind physical damage to sprinkler systems. A single accidental impact can crack a sprinkler head, break a riser, or even damage the underground pipes connected to it. These breaks can cause dramatic geysers of water, flooding your lawn and wasting a tremendous amount of water in a short time.

How to Prevent Mowing-Related Damage

Mark Your Heads: Place small flags or “donut” guards around your sprinkler heads to make them more visible while mowing.
Install Swing Joints: A swing joint is a flexible pipe assembly installed between the lateral line and the sprinkler head. It allows the head to move or “swing” upon impact without breaking the pipe, significantly reducing the risk of damage.
Ensure Proper Setback: Install sprinkler heads several inches away from hardscapes like driveways, walkways, and curbs to protect them from edgers and vehicle tires.
Perform Seasonal Inspections: Before you start your heavy mowing season in the spring, walk your property and check each sprinkler head for any existing damage. A quick check can prevent a major headache later.

If a head is already broken, it’s crucial to replace it promptly to prevent water waste and ensure your lawn remains healthy.

Frequently Asked Questions (FAQ)

Q: How often should I have my sprinkler system professionally inspected?
A: We recommend a professional inspection at least once a year, typically in the spring before you start regular watering. This allows a technician to identify any issues that may have occurred over the winter, adjust heads, and ensure your controller is programmed for efficiency.

Q: My water bill went up, but I don’t see any leaks. What should I do?
A: An unexplained increase in your water bill is a classic sign of a hidden leak, often from a faulty underground valve or a cracked pipe. The best course of action is to call a professional for a comprehensive system audit. We can use specialized equipment to locate and repair hidden leaks before they cause more damage.

Q: Can I replace a broken sprinkler head myself?
A: Yes, replacing a single broken head is a manageable DIY project for many homeowners. Just be sure to purchase the exact same make and model of sprinkler head for compatibility. However, if you’re unsure or if the problem involves the underlying pipes, it’s safer and more effective to call a professional.

Q: What is a “smart” irrigation controller?
A: A smart controller is a Wi-Fi-enabled device that automatically adjusts your watering schedule based on real-time local weather data, forecasts, soil type, and plant needs. It helps prevent overwatering (e.g., it won’t run after it rains) and is one of the best investments you can make to conserve water and lower your utility bills.
