4 Common Sprinkler Issues & Solutions in Pinehurst

Is your lawn looking less than lush? Brown spots, dry patches, and water stains on your driveway might be signs that your sprinkler system isn’t working correctly. If you’re dealing with any of these issues, Mr. Sprinkler Repair in Pinehurst is your go-to expert for fast, reliable solutions. A healthy, green lawn depends on a properly functioning irrigation system. When problems arise, they can waste water, damage your landscape, and run up your utility bills.

This post will explore four of the most common sprinkler issues Pinehurst homeowners face and show how Mr. Sprinkler Repair can provide expert solutions for each problem. We’ll break down the causes and explain why professional repair is often the best solution for a vibrant, beautiful yard.

1. Unsightly Water Stains on Pavement

Have you noticed dark, stubborn stains on your driveway, sidewalk, or patio? These are often caused by sprinkler overspray. When sprinkler heads are misaligned or the wrong type for the area, they spray water onto hard surfaces instead of your lawn. The minerals and sediments in the water build up over time, leaving behind ugly discoloration that is difficult to remove.

Why Overspray Happens

Overspray is more than just a cosmetic issue; it’s a major source of water waste. Common culprits include:

Misaligned Sprinkler Heads: Over time, sprinkler heads can get knocked out of position by lawnmowers, foot traffic, or shifting ground.
Incorrect Nozzles: Using a nozzle designed for a wide spray pattern in a narrow garden bed will inevitably lead to overspray.
High Water Pressure: Excessive pressure can cause water to mist and drift, landing far beyond its intended target.

A professional can assess your system, reposition sprinkler heads, and install the correct nozzles to ensure water lands exactly where it’s needed—on your grass and plants, not your pavement.

2. Insufficient Water Pressure

Does your sprinkler system produce more of a weak trickle than a powerful spray? Low water pressure is a frustrating problem that prevents your lawn from getting the hydration it needs. Sprinkler heads are designed to operate within a specific pressure range (PSI). When the pressure drops too low, the heads may not pop up fully, and water won’t reach the edges of your lawn.

What Causes Low Pressure?

Several factors can contribute to a drop in water pressure:

Leaks in the Line: A cracked or broken pipe underground is a common cause. This not only lowers pressure but also creates a hidden swamp in your yard.
Clogged Components: Debris, dirt, or mineral buildup can clog pipes, valves, or individual sprinkler heads.
Backflow Preventer Issues: A malfunctioning or partially closed backflow preventer can restrict water flow to the entire system.
System Overload: Sometimes, a single zone has too many sprinkler heads, exceeding the capacity of the water line.

Diagnosing low pressure requires a systematic approach. An experienced technician can locate hidden leaks, clear blockages, and reconfigure zones to restore proper pressure and ensure your sprinklers operate effectively.

3. Gaps in Coverage (Dry Spots)

If you have green patches right next to brown, struggling turf, you likely have gaps in your sprinkler coverage. This “head-to-head” coverage is essential for uniform watering. Each sprinkler head should spray far enough to reach the next one in the zone. When a system is poorly designed or heads are blocked, you get uneven watering that results in an inconsistent, patchy lawn.

Reasons for Poor Coverage

Gaps in sprinkler coverage are often due to design flaws or obstructions.

Poor Initial Layout: The original system design might not have accounted for the specific needs of your landscape, leaving certain areas dry.
Obstructions: Growing trees, new landscaping features, or even lawn furniture can block the spray from a sprinkler head.
Sunken Sprinkler Heads: Heads that have sunk too low into the ground can’t pop up high enough to spray over the surrounding grass.
Wrong Spray Pattern: Using a 90-degree nozzle in a space that needs 180-degree coverage will leave half the area completely dry.

A professional irrigation audit can identify these gaps. We can adjust the system layout, raise sunken heads, trim obstructions, and swap out nozzles to guarantee every square inch of your lawn receives the water it needs to thrive.

4. System Underwatering and Brown Spots

Sometimes, the whole lawn looks stressed, with widespread brown spots and a generally tired appearance. This is often a sign of underwatering. The system might be running, but it’s not delivering enough water to meet your lawn’s needs. This is especially true during the hot, dry spells we experience in Pinehurst.

Is Your System Watering Enough?

Underwatering can happen even when your system seems to be working.

Incorrect Run Times: Your watering schedule might be too short. Lawns need deep, infrequent watering to encourage strong root growth.
Clogged Nozzles: A tiny pebble or piece of dirt can partially or fully clog a nozzle, drastically reducing its water output.
Controller Malfunctions: An old or faulty controller might not be running the programmed schedule correctly, or it may have reset after a power outage.

Determining the right amount of water for your lawn involves considering grass type, soil condition, and sun exposure. A sprinkler specialist can perform a catch-cup test to measure exactly how much water your system delivers and program your controller for optimal efficiency. This ensures your lawn gets just the right amount of hydration without wasting a drop.
