When one zone on your irrigation system stops working, it's easy to assume the controller is the culprit. You check the settings, reset the timer, maybe mess with the wiring - and nothing changes. Here's the thing: the controller isn't always where the problem lives.
Tree roots are one of the most common causes of a dead irrigation zone, and they're one of the hardest to spot without knowing what to look for. A root doesn't have to be massive to do serious damage. Over time, even moderate root growth can wrap around a line, compress it, or crack it completely. Water stops moving. The zone goes silent. And most homeowners have no idea why.
What we pulled out of the ground here tells the whole story. The irrigation pipe was completely crushed by a tree root - split on both sides, with zero chance of water passing through. No amount of controller adjustments or zone resets was going to fix that. The only solution was to dig down, find the break, and replace the damaged section of line.
This is exactly why irrigation repair isn't just about swapping parts. It's about diagnosing correctly first. We've seen plenty of situations where someone replaced a controller or installed new heads, only to find the real issue was underground the whole time. Skipping the diagnostic step wastes money and leaves the actual problem in place.
If one of your zones has gone quiet and you can't figure out why, don't just assume it's an easy fix. It might be. But it might also be something like this - buried, out of sight, and quietly getting worse. We'll track it down and get it sorted.
