Top 4 Sprinkler Issues in Jersey Village & How to Fix Them

Keeping a lush green lawn in Jersey Village requires more than just a timer; it requires a system that works perfectly. Many homeowners set their irrigation and forget it, only to find brown patches or soggy puddles weeks later. Because these systems are complex, a single failing part can jeopardize your entire landscape.

If you are noticing dry spots, spiked water bills, or wilting plants despite regular watering, your system likely needs professional attention. At Jersey Village Sprinkler Repair, we specialize in diagnosing these common local issues. In this guide, we will break down the four most frequent sprinkler problems we see in the area and show you how to address them before they ruin your curb appeal.

1. System Underwatering: The Silent Lawn Killer

You might think your sprinklers are doing their job because you see them pop up every morning. However, just because water is spraying doesn’t mean enough of it is reaching the roots. Underwatering is a deceptive issue because it often looks like a disease or pest problem at first glance.

The Problem and Impact

Underwatering usually happens due to poor coverage, clogged nozzles, or incorrect timer settings for the season. In the Texas heat, evaporation happens quickly. If your system puts out a mist rather than a steady stream, or if the duration is too short, the water never penetrates deep into the soil.

The impact is immediate and ugly. You will start to see “hot spots”—patches of grass that turn blue-gray and then straw brown. These stressed areas are weak, making them prime targets for chinch bugs and fungal diseases. Once the soil dries out completely, it becomes hydrophobic, meaning it actually repels water, making recovery even harder.

How to Fix It

  • Audit your run times: Check your controller. During peak summer months, you may need to increase the duration of each zone.
  • The “Tuna Can” Test: Place empty tuna cans or small cups across your lawn. Run the sprinklers for 15 minutes. If the cans aren’t filling up evenly or barely have water in them, you need to adjust your heads or run times.
  • Check for obstructions: Ensure growing shrubs or tall grass aren’t blocking the spray pattern of your sprinkler heads.

2. Improper Pipe Sizing: Choking Your Water Flow

This is often an installation error that haunts homeowners years later. A sprinkler system relies on hydraulic calculations to ensure that the water pressure and flow rate (gallons per minute) are balanced. When pipes are too small for the volume of water required, the system chokes.

The Problem and Impact

When a zone demands more water than a narrow pipe can supply, the velocity of the water increases to dangerous levels. This causes a significant drop in pressure at the sprinkler heads.

The impact is visibly weak performance. You won’t see crisp, strong sprays; instead, you’ll see heads that barely pop up or simply dribble water. This leads to uneven coverage where the grass near the head gets soaked, but the grass three feet away stays dry. Over time, high water velocity in small pipes can also cause “water hammer”—a banging noise in the pipes—which can eventually rupture fittings and cause leaks.

How to Fix It

  • Zone splitting: If a single zone has too many heads for the pipe size, a professional can split it into two separate zones to reduce the demand on that specific line.
  • Change nozzles: You can switch to high-efficiency rotary nozzles. These emit water slowly in rotating streams, requiring less flow (GPM) than traditional spray nozzles, which can sometimes compensate for undersized piping.
  • Repiping: In severe cases, the only permanent solution is digging up the restrictive section and installing larger diameter PVC pipe.

3. Sprinkler Heads Too Close to Plants: A Recipe for Root Rot

Landscapes evolve. That small shrub you planted five years ago is now a massive hedge. Unfortunately, the sprinkler head installed next to it hasn’t moved. When hardscaping or planting designs change without adjusting the irrigation layout, heads often end up buried inside foliage or right against a plant’s base.

The Problem and Impact

When a sprinkler head is blasting water directly into the base of a plant from inches away, it saturates the soil excessively in that one spot. Most plants hate having “wet feet.”

The impact is root rot. The roots drown because the soil is constantly waterlogged, cutting off oxygen. Ironically, the plant will look wilted (similar to underwatering), leading homeowners to water more, which kills the plant faster. Furthermore, the spray is blocked by the plant, creating a “shadow” behind it where the grass dies from lack of water.

How to Fix It

  • Relocate the heads: The most effective fix is to dig up the head and use funny pipe (flexible tubing) to move it 6 to 12 inches away from the plant’s canopy.
  • Switch to drip irrigation: For flower beds and dense shrubbery, abandon the spray heads entirely. Cap them off and install a drip line conversion. Drip irrigation delivers water directly to the soil slowly, bypassing foliage and preventing the blast damage.
  • Pruning: While less permanent, keeping plants trimmed back aggressively around sprinkler heads can temporarily restore the spray pattern.

4. In-Ground Leaks: The Invisible Wallet Drainer

Perhaps the most frustrating issue for Jersey Village residents is the leak you can’t see. PVC pipes can crack due to shifting soil, invasive tree roots, or freeze damage during our occasional winter snaps.

The Problem and Impact

An underground leak on a zone line might only leak when that specific zone is running, making it hard to spot. If it’s on the main line, it leaks 24/7.

The impact goes beyond a high water bill. Underground leaks erode the soil beneath your lawn or driveway, potentially causing sinkholes or structural shifting. You might notice a patch of grass that is surprisingly lush and green compared to the rest, or a squishy area of mud that never dries out. Meanwhile, the rest of the zone loses pressure, leading to dry spots elsewhere.

How to Fix It

  • Check the water meter: Turn off all water inside the house. Check your water meter. If the little triangle or dial is still moving, you have a leak.
  • Look for pressure loss: If one zone suddenly has much lower pressure than the others, the leak is likely on that zone’s lateral line.
  • Professional detection: Because digging up your whole yard is destructive, professional repair services use specialized listening equipment and moisture sensors to pinpoint the exact location of the break before digging.

Don’t Let Irrigation Issues Ruin Your Landscape

A broken sprinkler system wastes money and damages your property. Whether you are dealing with mysterious brown spots, weak pressure, or a leak you just can’t find, guessing usually leads to more frustration.
