1. Manual Override Malfunctions

Your system’s manual override function is crucial for testing zones, making adjustments, or watering a specific area outside of your regular schedule. When it stops working, it can be a sign of a deeper electrical issue.

How to Spot the Problem

The most obvious sign is that your system doesn’t respond when you try to start a watering cycle manually from the controller. You might turn the dial to a specific zone and hit “start,” but nothing happens. The controller may appear to be working, but the valves in the yard don’t open to release water.

What Causes It?

Manual override issues often point to a problem with communication between your controller and the valves. Common culprits include:

• A Faulty Controller: The internal components of the control panel can wear out over time.
• Wiring Problems: A frayed, cut, or disconnected wire somewhere between the controller and the valve will break the circuit.
• Solenoid Failure: Each valve has a solenoid, an electromagnetic component that opens the valve when it receives a signal. If the solenoid is burnt out, the valve won’t open.

What You Can Do

First, check your controller’s settings to ensure it’s not in an “off” or “rain” mode that would prevent manual operation. You can also inspect the wiring at the control panel for any loose connections. However, diagnosing and repairing electrical faults can be complex and potentially hazardous if you’re unfamiliar with irrigation systems. A professional can use specialized tools like a multimeter to trace the electrical signal, pinpoint the exact point of failure, and safely replace the faulty component.

2. Poor Soil Absorption and Water Runoff

Have you ever noticed water pooling on your lawn or running down the sidewalk just minutes into a watering cycle? This indicates your soil isn’t absorbing water as quickly as your sprinklers are delivering it. This is not only wasteful but can also lead to an unhealthy lawn.

How to Spot the Problem

The most apparent signs are puddles forming in your yard or water streaming across driveways and sidewalks. You might also notice that the soil is hard and compacted, or your lawn has a significant thatch layer—a dense mat of dead grass and roots—that acts as a barrier. Sloped areas of your yard are particularly prone to runoff.

Why It’s a Problem

Poor absorption means your grassroots aren’t getting the deep watering they need to grow strong. Instead, the water evaporates or flows away, wasting a valuable resource and increasing your water bill. This shallow watering encourages weak root systems, making your lawn more vulnerable to drought and disease.

What You Can Do

You can implement a “cycle and soak” watering schedule. This involves breaking up your watering time into shorter, multiple cycles with a pause in between. For example, instead of watering for 20 minutes straight, you could run the zone for 10 minutes, wait an hour, and then run it for another 10 minutes. This gives the soil time to absorb the water.

Core aeration is another effective solution. This process removes small plugs of soil from your lawn, which reduces compaction and allows water, air, and nutrients to reach the root zone more easily. While DIY aeration tools are available, a professional service ensures the job is done thoroughly and effectively for the best results.

3. Leaky Sprinkler Valves

A leaking valve is a silent money-waster. Since the valves are often buried in underground boxes, a leak might go unnoticed for weeks, wasting hundreds of gallons of water and causing your water bill to skyrocket.

How to Spot the Problem

Keep an eye out for these telltale signs:

• Constantly Wet Areas: A patch of lawn that is always soggy or muddy, even when the sprinklers haven’t run recently.
• Low Water Pressure: If your sprinklers seem weaker than usual or don’t pop up fully, a leak could be diverting water pressure.
• Water Trickling from a Sprinkler Head: A single head that continues to drip or spray lightly long after the system has shut off is a classic sign of a valve that isn’t closing completely.
• A Puddle Around the Valve Box: If you see water pooling around or inside the valve box, you likely have a leak.

What Causes It?

Valves can fail for several reasons. Debris like sand, dirt, or small pebbles can get stuck inside the valve, preventing it from creating a tight seal. The internal diaphragm, a rubber component, can also wear out, tear, or become distorted over time, which compromises the seal.

What You Can Do

You can try to fix a leaky valve by turning off the water supply, opening the valve, and cleaning out any visible debris. However, this can be a messy job, and reassembling the valve correctly is critical. If the diaphragm is torn or warped, it will need to be replaced. Given the variety of valve types and sizes, getting the right replacement part can be challenging. A professional technician can quickly identify the valve model, diagnose the exact cause of the leak, and perform a reliable repair or replacement.

4. Damage from Mowing

Sprinkler heads and pipes are often the victims of accidental encounters with lawnmowers and edgers. A single pass can crack a sprinkler head, snap a riser, or even damage a shallow pipe.

How to Spot the Problem

This is usually the easiest problem to identify. You might see a broken or tilted sprinkler head immediately after mowing. When the system runs, you’ll likely see a geyser of water shooting up from the damaged head or water bubbling up from the ground where a pipe is broken. This leads to uneven coverage, with one area getting flooded while others get no water at all.

How to Prevent It

Proper installation is the best prevention. Sprinkler heads should be installed at the correct height so they pop up to water and retract fully below the turf, out of the mower’s path. It’s also helpful to mark the location of your sprinkler heads with small flags before you mow, especially if you’re new to the property or have recently adjusted your system.

What You Can Do

Replacing a broken sprinkler head is a manageable DIY task for some homeowners. You’ll need to dig around the head, unscrew the broken unit from the riser, and screw on a new one. Be sure to buy the correct replacement head with the right spray pattern and radius for that location.

However, if the damage extends to the pipe or fitting below the head, the repair becomes more complex. Fixing underground pipes requires careful digging, cutting out the damaged section, and fitting new pipe, which can be difficult without the right tools and experience. For these more extensive repairs, calling a professional is the quickest way to get your system back in working order.
