Broken or Damaged Sprinkler Heads

A broken sprinkler head is one of the most visible and common irrigation problems. Whether it’s a geyser shooting water into the air or a head that won’t pop up at all, this issue directly impacts your lawn’s health and your water bill.

What Causes Broken Sprinkler Heads?

Sprinkler heads are tough, but they aren’t indestructible. They often break due to:

Lawnmower Damage: Running over a sprinkler head with a lawnmower or edger is the number one cause of breakage.
Foot Traffic: Heavy foot traffic from kids playing or regular pathways across the lawn can put enough pressure on a head to crack it.
Weather Conditions: The intense Texas sun can make plastic parts brittle over time, and sudden freezes can cause cracks.
Improper Installation: Heads installed too high are vulnerable to mowers, while those set too low can get clogged with dirt and fail to pop up.

Symptoms and How to Check

Spotting a broken head is usually straightforward. Look for these signs:

Water gushing from one spot in your yard.
A sprinkler head that is visibly cracked, shattered, or missing.
A dry, brown patch on your lawn where a sprinkler should be watering.
A head that doesn’t pop up or retract properly.

To check, run your sprinkler system for a few minutes and walk your property. Watch each zone activate and pay close attention to how each head performs.

When to Call for Sprinkler Head Replacement

While some handy homeowners can replace a simple pop-up head, it can be tricky. You need to get the right model, ensure the height is perfect, and avoid damaging the underground lines. If you notice multiple broken heads, are unsure which replacement part to buy, or suspect the problem is with the pipe underneath, it’s best to call a professional. An expert can perform a sprinkler head replacement quickly and correctly, ensuring optimal coverage and preventing future leaks.

Faulty Sprinkler Valve Diaphragms

If a whole zone of your sprinkler system isn’t working—or won’t shut off—the problem might be a faulty valve. Inside each valve is a rubber component called a diaphragm, which acts as a seal. Over time, this part can wear out, get clogged with debris, or tear.

What Causes a Valve Diaphragm to Fail?

Age and Wear: Like any rubber part, diaphragms simply wear out after years of use.
Debris: Small rocks, sand, or dirt can get lodged in the valve, preventing the diaphragm from creating a tight seal.
Water Pressure Issues: Extremely high water pressure can put stress on the diaphragm, leading to premature failure.

Symptoms of a Bad Diaphragm

A faulty diaphragm typically causes two main problems:

A Zone Won’t Turn On: A diaphragm stuck in the closed position prevents water from flowing to the sprinklers in that zone. You’ll turn on the system, but one area will remain dry.
A Zone Won’t Turn Off: A torn or debris-clogged diaphragm can’t seal properly, allowing water to leak through continuously. This leads to a constantly running zone, soggy patches, and a high water bill.

When to Call for Valve Diaphragm Repair

Sprinkler valves are housed in underground boxes and can be complex to diagnose and repair. You risk causing more damage to the valve or its wiring if you’re not familiar with the components. If an entire zone is misbehaving, it’s a clear sign you need a professional inspection. A specialist in sprinkler repair in Glenn Heights can locate the valve box, identify the faulty part, and perform a valve diaphragm repair without disrupting your entire system.

Backflow Preventer Issues

Your backflow preventer is a critical safety device on your irrigation system. Its job is to ensure that water from your sprinklers—which can contain fertilizers, pesticides, and other contaminants—never flows backward into your home’s clean drinking water supply. A malfunctioning backflow preventer is a serious health hazard.

Why Backflow Preventers Fail

These devices can fail due to frozen and cracked pipes, worn-out internal seals, or debris interfering with their check valves. In Texas, municipalities require annual testing to ensure they are functioning correctly for the safety of the public water supply.

Signs of a Backflow Preventer Problem

Constant Leaking or Dripping: A properly working backflow preventer should not leak.
Discolored or Smelly Water: If you ever notice odd-smelling or yellowish water from your taps, it could indicate a backflow issue. Shut off your water and call a licensed plumber and irrigation specialist immediately.
Notice of Non-Compliance: Your city may send you a notice if you are overdue for your mandatory annual backflow preventer testing.

Safety First: When to Call a Pro

Do not attempt to repair a backflow preventer yourself. This is a job that legally requires a licensed professional. Only a certified technician has the specialized tools and training to perform backflow preventer testing and repairs. At Mr. Sprinkler Repair, we have licensed experts who can ensure your device is working perfectly and keeping your family’s water safe.

Irrigation Short Cycling

Does your sprinkler system turn on for a minute, shut off, and then immediately turn back on? This is called “short cycling.” It’s not only inefficient but can also cause serious wear and tear on your system’s components, especially the pump and valves.

What Causes Short Cycling?

Short cycling can be caused by several issues, from simple programming errors to more complex hardware failures.

Controller Malfunctions: A faulty controller or incorrect programming can send mixed signals to the valves.
Low Water Pressure: If the system detects a significant drop in pressure, it might shut down as a protective measure.
Faulty Master Valve or Pump Relay: These components control the water flow for the entire system, and a failure can lead to erratic behavior.
A Leak Somewhere in the System: A major leak can cause a pressure drop that triggers the system to shut down and restart.

What to Do About It

First, check your controller’s programming to make sure the start times and run times for each zone don’t overlap or conflict. If the settings look correct, the problem is likely more technical. Irrigation short cycling puts a lot of stress on your system, leading to more expensive repairs down the road. It’s best to get it diagnosed quickly.

When to Call a Sprinkler Expert

Because short cycling can have many different causes, pinpointing the source requires professional diagnostic tools and experience. An irrigation specialist can test the electrical signals, check the water pressure, and inspect the valves and pump to find the root cause and fix it efficiently.

Frequently Asked Questions (FAQ)

Q: How often should I have my sprinkler system inspected?
A: We recommend a professional inspection at least once a year, preferably in the spring before you start watering heavily. This helps catch small problems before they become big, expensive ones.

Q: Why is one part of my lawn soggy while another is dry?
A: This is usually caused by either a broken sprinkler head in the soggy area or a valve that’s stuck open. The dry area could be served by a clogged nozzle or a valve that isn’t opening at all. An inspection can pinpoint the exact cause.

Q: Is it okay to fix a small leak myself?
A: For a simple issue like replacing a single pop-up head, a DIY repair is possible. However, for underground leaks, valve issues, or backflow problems, it’s always safer and more effective to call a professional. Improper repairs can lead to bigger leaks and more costly water damage.

Q: How much water does a leaky sprinkler system waste?
A: Even a small leak can waste thousands of gallons of water over a single watering season. A broken head or a stuck valve can waste hundreds of gallons in just a few hours, leading to a surprisingly high water bill.
