Sprinkler & Irrigation FAQs

A sprinkler system that won't turn on usually comes down to power, the controller, or the wiring. It's worth confirming the basics first: that the controller has power and shows the correct time and date, and that your main water supply is open. Beyond that, a tripped breaker, blown fuse, bad solenoid, or a wiring fault can all shut the system down; and those are harder to track down without the right tools. If the quick checks don't do it, we'll pinpoint the cause fast and, in most cases, have you running the same day.

Low pressure at the heads is usually one of a few things: a partially closed main valve, clogged nozzles, or a leak somewhere in the line. Cleaning a visibly clogged head and making sure your valves are fully open is a fair first step. But if the pressure stays low or you're seeing soggy spots in the yard, you're likely dealing with a hidden line leak or a valve problem, and that's where we come in. We'll find the source and fix it without the guesswork.

A sprinkler timer that's gone dark or keeps resetting is usually a power problem, a dead backup battery, or an internal fault. Swapping the backup battery is an easy thing to rule out yourself. If the display stays blank, the settings won't hold, or it resets on its own, the controller itself is likely failing; and choosing and wiring the right replacement is worth having done properly. We can recommend and install a reliable controller, including smart models that adjust to the weather and trim your water bill.

Leaking heads usually point to debris in the valve, a worn seal, or low-head drainage, which is when water drains out of the lowest heads after the system shuts off. If you can see cracks in the head itself, that part needs replacing. Persistent leaks and drainage issues are typically solved by replacing worn components or installing check valves, and getting the right parts fitted correctly is what makes the fix last. We'll sort out which it is and stop the leak for good.

A single stuck zone almost always traces back to the valve or its solenoid. If the zone is stuck on, the valve is probably held open by debris or a failing solenoid; if it's stuck off, it's likely not getting power or the solenoid has failed. Diagnosing this means testing the wiring at both the controller and the valve, fiddly work where a wrong move can make things worse. It's a common repair for us, and usually a quick one once we've confirmed the cause.

Water pooling in one spot usually means a leaking pipe, a broken sprinkler head, or a drainage problem. If it pools only while a zone is running, a cracked head or line is the likely culprit; if it pools even when the system is off, you're probably looking at low-head drainage or a valve that isn't sealing shut. Standing water can damage your lawn and even your foundation over time, so it's worth addressing early. We'll trace it to the source, and if it turns out to be a grading or drainage issue, we install French drains and drainage solutions too.

Repair costs depend on the issue and the parts and labor involved; a single head is minor, while a hidden line leak or a controller replacement runs more. We keep it simple: we estimate up front, with honest pricing, and only the work you actually need. You'll approve the cost before we start, so there are no surprises.

Some things you can handle yourself like cleaning a clogged nozzle or swapping a backup battery, for example. But most sprinkler problems involve wiring, valves, water pressure, or hidden leaks, and those need the right tools and a trained eye. A wrong guess there can turn a small repair into an expensive one. If you're not sure what you're dealing with, we'll diagnose it quickly, tell you straight what it needs, and only recommend what's necessary. We're licensed and insured and always happy to help.
