4 Common Sprinkler Problems in Corinth

A healthy, green lawn is a point of pride for any Corinth homeowner. But keeping it that way during the hot, dry North Texas summers requires a reliable sprinkler system.

We’ve created this guide to share our local expertise and help you spot the most common sprinkler problems before they turn into bigger headaches.

1. Water Hammer: That Loud Banging in Your Pipes

Have you ever heard a loud banging or thudding sound coming from your walls or yard right after your sprinkler system turns off? That startling noise is called water hammer. It happens when a fast-closing valve abruptly stops the flow of water, causing a pressure spike that sends a shockwave back through the pipes.

What Causes Water Hammer?

The primary cause is high water pressure combined with sprinkler valves that snap shut too quickly. Over time, this constant banging can damage your pipes, loosen fittings, and lead to costly leaks.

How to Diagnose It

Listen carefully when your sprinkler system cycles through its zones. The banging noise typically occurs a second or two after one zone valve closes and before the next one opens. If you hear that distinct “thud,” you likely have a water hammer issue.

Simple Fixes and When to Call a Pro

For a handy homeowner, there are a few things to try. Some modern sprinkler valves have a flow control feature, which you can adjust to slow the water speed and soften the closing action.

However, the most effective and permanent solution is installing a water hammer arrestor. This small device acts as a shock absorber, cushioning the pressure spike with a chamber of compressed air. While some DIY kits are available, installing an arrestor correctly into your main irrigation line is a job best left to a professional sprinkler technician. A licensed pro can ensure it’s placed correctly for maximum effect and won’t create a future leak point.

2. Electrical Failures: When the System Won’t Start

You’ve set your controller, but nothing happens. The sprinklers won’t turn on, or only certain zones work. More often than not, the culprit is an electrical failure. Your irrigation system relies on a low-voltage electrical circuit to function, and problems can arise with the controller, wiring, or solenoids.

Common Symptoms

• The sprinkler controller display is blank.
• The system won’t run automatically or manually.
• One or more zones fail to activate.
• Fuses in the controller keep blowing.

Safe Basic Checks You Can Do

Before calling for service, there are a couple of safe checks you can perform. First, check the circuit breaker for your sprinkler system in your home’s main electrical panel. If it’s tripped, reset it once. If it trips again, there’s a short circuit that needs professional attention.

Next, open your controller box and look for a wire labeled “Common” or “C.” This wire connects to all your valves. Gently tug on it to ensure it hasn’t come loose from its terminal. A disconnected common wire is a frequent cause of system-wide failure.

Professional Solutions

If those basic checks don’t solve the problem, it’s time to call a sprinkler repair expert. Electrical troubleshooting can be complex and requires specialized tools. A technician can test for a faulty transformer, locate and repair damaged or shorted underground wiring, or diagnose a failed solenoid on a specific valve. Attempting these repairs without proper training can lead to further damage to your system or even electrical shock.

3. Misdirected Sprinkler Heads: Watering Everything But the Lawn

Are you watering more of your sidewalk, fence, or driveway than your grass? Misdirected sprinkler heads are an incredibly common and wasteful problem. They can result from being bumped by a lawnmower, natural ground settling, or improper initial installation.

This issue not only starves parts of your lawn of water, creating dry spots, but it also sends your water bill soaring. Watering impermeable surfaces is literally pouring money down the drain.

How to Identify and Realign Heads

Walk your property while the system is running. Look for heads that are tilted, spraying a fine mist instead of droplets (indicating high pressure), or shooting water far beyond the lawn’s edge.

For many pop-up spray heads, you can realign them by hand. While the zone is active, firmly grip the pop-up riser stem and gently twist it until the spray pattern is aimed correctly. For rotor heads, you may need a special key to adjust the arc and direction.

If a head is simply spraying too far, it might have the wrong nozzle. Nozzles are interchangeable and come in various patterns (90°, 180°, 360°) and spray distances. Replacing a nozzle is a simple, inexpensive fix that can have a huge impact.

4. Clogged Nozzles: Poor Flow and Dry Spots

If you notice a sprinkler head that’s sputtering, dribbling, or not spraying at all, it’s likely clogged. The small opening in a sprinkler nozzle is easily blocked by dirt, sand, small pebbles, or other debris that finds its way into the irrigation lines.

Common Causes and Cleaning Steps

Debris can enter the system during a municipal water line repair or from within your own pipes.

Cleaning a nozzle is a straightforward task.

1. Unscrew the nozzle from the top of the sprinkler head (it’s often easier to pull up the pop-up riser first).
2. Rinse the nozzle and the small filter screen located just beneath it under running water.
3. Use a thin wire or a paperclip to gently dislodge any stubborn debris from the nozzle opening.
4. Before reassembling, run the sprinkler zone for a moment with the nozzle removed to flush out any loose debris from the line itself.
5. Screw the filter and nozzle back on, and you’re done.

For recurring clogs, a professional can inspect your system and recommend installing a line filter to catch debris before it reaches the heads.

Here in Corinth, our clay-heavy soil and intense summer heat put unique demands on irrigation systems.
