This guide will walk you through four frequent problems homeowners face with their sprinkler systems. We’ll explore why these issues happen, what you can do about them, and how professional maintenance can protect your investment and keep your lawn looking its best.

1. The Wrong Watering Schedule

One of the most common yet overlooked issues is an inappropriate watering schedule. The “set it and forget it” approach often leads to either overwatering or underwatering, both of which are detrimental to your lawn and garden.

Why It’s a Problem

In the Texas heat, it’s tempting to water your lawn every day, but this can be a mistake. Watering too frequently encourages shallow root growth, making your grass less resilient to drought. It also creates a damp environment perfect for fungal diseases and pests. On the other hand, watering too little or for too short a duration stresses your lawn, leading to brown spots and weak, brittle grass. An incorrect schedule is also a leading cause of water waste, driving up your utility bills.

DIY Solutions

• Adjust for the Season: Your lawn’s water needs change throughout the year. Decrease watering frequency in the cooler spring and fall months and increase it during the peak heat of summer.
• Water Deeply, Less Often: Instead of a short, daily sprinkle, aim for longer watering sessions two to three times a week. This encourages deep root growth, creating a stronger, more drought-tolerant lawn. A good rule of thumb is to provide about one inch of water per week. You can measure this by placing a few empty tuna cans around your yard while the system runs.
• Time It Right: Water in the early morning, typically between 4 a.m. and 8 a.m. This minimizes evaporation from the sun and wind and allows the grass to absorb the moisture before nightfall, reducing the risk of fungus.

When to Call a Pro

If you’ve adjusted your timer and still see signs of distress, a professional can help. An irrigation specialist can assess your landscape’s specific needs, check for underlying issues like low water pressure, and program your controller for optimal efficiency. They can also recommend and install a smart irrigation controller, which automatically adjusts watering schedules based on local weather data.

2. Inconsistent Valve Operation

Your sprinkler system’s valves are like gates that control the flow of water to different zones in your yard. When they don’t open or close properly, you’ll notice significant problems with water distribution.

Why It’s a Problem

A valve stuck open will cause a specific zone to run continuously, flooding the area and wasting enormous amounts of water. Conversely, a valve that won’t open at all will leave a zone completely dry, quickly killing the grass and plants. Irregular operation, where a valve flutters or only partially opens, results in low pressure and poor coverage, creating a patchy, unhealthy lawn.

DIY Solutions

• Check the Controller: Before inspecting the valve itself, ensure the controller is programmed correctly and sending a signal to the right zone.
• Clean the Valve: Debris like dirt, sand, or small pebbles can get lodged inside a valve, preventing it from closing completely. After shutting off the water supply, you can carefully disassemble the valve, clean its components (especially the diaphragm and solenoid), and reassemble it.
• Inspect the Solenoid: The solenoid is an electromagnetic component that opens the valve. If it’s faulty, the valve won’t operate. You can test it with a multimeter or try swapping it with a known working solenoid from another valve.

When to Call a Pro

Valve repair can be tricky and involves working with both water lines and electrical components. If you’re not comfortable disassembling the valve, can’t locate the valve box, or suspect a wiring issue between the controller and the valve, it’s best to call a professional. A technician can quickly diagnose the problem, whether it’s a bad solenoid, a torn diaphragm, or an electrical fault, and perform the repair safely.

3. Water Stains on Pavement

Do you have persistent wet spots or unsightly stains on your driveway, sidewalk, or patio? This is a clear sign that your sprinkler system is watering the concrete instead of your lawn.

Why It’s a Problem

Besides being visually unappealing, overspray is incredibly wasteful. Every gallon of water that lands on pavement is a gallon lost. Over time, hard water deposits can leave stubborn mineral stains that are difficult to remove. In some cases, constant moisture near your home’s foundation can contribute to soil shifting and potential structural damage.

DIY Solutions

• Adjust Sprinkler Heads: Most sprinkler heads can be adjusted by hand. Simply twist the head to redirect the spray pattern away from paved surfaces. For pop-up spray heads, you may need a small screwdriver or a special adjustment tool to change the spray arc and radius.
• Clear Obstructions: Sometimes, overgrown grass or landscaping can block or deflect the water spray. Trim any vegetation that might be interfering with the sprinkler’s intended path.
• Check for Tilted Heads: A sprinkler head that is leaning or tilted will not spray evenly. Make sure the head is sitting perpendicular to the ground. You may need to dig around it and pack soil underneath to straighten it.

When to Call a Pro

If basic adjustments don’t solve the problem, you may need a different type of sprinkler head or nozzle. An irrigation expert can assess the area and recommend heads with more precise spray patterns, such as those with adjustable arcs or specialized nozzles for narrow strips of grass. They can also address underlying issues like high water pressure that can cause misting and overspray.

4. Soil Erosion

Erosion occurs when water washes away topsoil, and it’s a serious threat to the health and stability of your landscape.

Why It’s a Problem

When your sprinkler system causes runoff, it carries away nutrient-rich topsoil, leaving your plants without the food they need to thrive. This can lead to exposed roots, destabilized plants, and ugly gullies in your lawn or garden beds. The runoff can also carry fertilizers and pesticides from your lawn into storm drains, impacting local water quality.

DIY Solutions

• Reduce Run Times: If you notice water pooling or running off before it can be absorbed, split your watering schedule into multiple, shorter cycles. For example, instead of watering for 20 minutes straight, run the zone for 10 minutes, wait an hour, and then run it for another 10 minutes. This “cycle and soak” method allows the soil to absorb the water more effectively.
• Check for Leaks: A broken pipe or a leaky sprinkler head at the bottom of a slope can cause significant erosion. Walk your property while the system is running to spot any unusual gushing or pooling.
• Aerate Your Lawn: Compacted soil, common in the Leander area, can prevent water from soaking in. Aerating your lawn annually helps loosen the soil and improve water absorption.

When to Call a Pro

If you have persistent erosion on slopes or in specific areas, a professional can provide a lasting solution. They might recommend installing low-flow sprinkler heads or converting the area to a drip irrigation system, which delivers water directly to the plant roots with minimal runoff. A professional can also re-grade the area or redesign your sprinkler zones for better water distribution on challenging terrain.
