System Troubleshooting & Diagnostics in New Braunfels, TX

Home / Single Services

Sometimes you know something is wrong with your irrigation system but you just can’t figure out what. The lawn looks uneven, the water bill crept up, or the system is behaving strangely — but everything looks fine on the surface. This is where most people get stuck, and where a lot of money gets wasted trying random fixes that don’t solve anything.

At New Braunfels Irrigation Co., we take a different approach. Before we recommend any repair or replacement, we find out exactly what’s causing the problem. Our troubleshooting and diagnostics service is built around one simple idea — fix the right thing the first time, not everything and hope for the best.

We’ve been diagnosing irrigation problems across New Braunfels and the Texas Hill Country for over 10 years. There’s very little we haven’t seen, and that experience means we get to the root of problems faster and more accurately than someone just guessing their way through your system.

When Do You Need Irrigation Diagnostics?

Not every irrigation problem is obvious. Some issues show up slowly over weeks or months. Others are hidden underground where you can’t see them at all. Here are some situations where a proper diagnostic check is exactly what’s needed:

Your lawn has dry patches even though the system runs on schedule
Certain zones seem weaker than they used to be
The system turns on but some areas are not getting watered
You notice water bubbling up from the ground between watering cycles
Your water bill has increased but nothing looks obviously wrong
The controller shows an error but you don't know what it means
A previous repair didn't fix the problem

Any of these situations calls for a proper diagnostic inspection — not a guess and a parts swap.

What We Can Diagnose

Our team is experienced with all types of irrigation system problems including:

Electrical faults between the controller and valves
Pressure loss caused by underground leaks
Valve failures — mechanical and electrical
Blocked or damaged sprinkler heads
Backflow preventer problems
Wiring damage from digging or landscaping work

How Our Troubleshooting Process Works

We go through your irrigation system in a structured, methodical way. We don’t skip steps and we don’t assume. Every zone gets tested, every component gets checked, and we document what we find along the way.

1. Controller & Programming Check

We start at the controller. We check the programming, confirm zones are set up correctly, look for error codes, and verify that the controller is sending proper signals to each valve. Many system problems start here and get misdiagnosed as hardware failures.

2. Zone by Zone Testing

We run each zone independently and observe what happens. We check how many heads activate, whether pressure looks right, how the spray patterns look, and whether anything shuts off or behaves unexpectedly. This gives us a clear picture of where problems are isolated.

3. Pressure Testing

Low or uneven pressure is one of the most common causes of poor irrigation performance. We test pressure at the supply point and within individual zones to identify drops that point to leaks, blockages, or valve problems.

4. Valve & Solenoid Testing

Valves are often the source of irrigation problems — either not opening fully, not closing properly, or failing electrically. We test each valve and its solenoid to confirm they’re operating correctly and responding to the controller.

5. Physical Inspection of Heads & Lines

We walk every zone and inspect heads for damage, clogging, misalignment, and proper pop-up height. We also look for surface signs of underground leaks like soft ground, pooling water, or unusual green patches between watering cycles.

6. Clear Report & Honest Recommendation

Once we’ve completed the diagnostic, we sit down with you and explain exactly what we found — in plain, simple language. We tell you what needs to be fixed, what’s optional, and what can wait. You get a clear price before any repair work begins.

Why Proper Diagnostics Saves You Money

It might be tempting to just start replacing parts and hope the problem goes away. Some contractors do exactly that — swapping out heads, valves, and controllers one by one until something works. The result is a big bill and sometimes the original problem still isn’t fixed.

A proper diagnostic inspection costs far less than a series of unnecessary repairs. When we know exactly what’s wrong before we start, we only fix what needs fixing. No wasted parts, no repeat visits for the same issue, no surprises on the final invoice.

Getting it right the first time is always cheaper than getting it wrong twice.
