After a Kansas winter, your irrigation system needs more than someone opening a valve. Done wrong or too early a spring startup can crack pipes, trigger water hammer, or miss the freeze damage hiding underground. Our irrigation turn-on service brings your system back online the right way: we wait for the freeze risk to pass, slowly re-pressurize the lines, run and inspect every zone and head, reset your controller for the season, and flag anything that needs repair before peak watering. You get full, even coverage from the first watering and no surprise leaks in July.
We charge your system slowly to avoid water hammer the pressure surge that cracks pipes, fittings, and valves when a system is turned on too fast.
We run each zone one at a time, checking heads for clogs, breaks, and alignment, and confirming full, even coverage across your lawn and beds
Startup is when freeze-cracked pipes and broken heads show up. We catch them now, before they waste water or dry out your lawn mid-summer.
We reprogram your controller including smart controllers like Rachio for the right seasonal watering schedule from day one.

The safe way is to open the main valve slowly to re-pressurize the lines (opening it fast can cause water hammer and crack pipes), turn the controller back on, then run each zone one at a time, checking every head for coverage and leaks, and reset your seasonal schedule. Many homeowners can do a basic startup, but the slow-charge step and spotting winter damage are where a professional turn-on pays for itself.
Wait until the risk of a hard freeze has passed in Johnson County that’s usually mid-to-late April into early May. Charging the lines while overnight temperatures still dip below freezing can crack pipes, valves, and heads. Turn it on too late, though, and your lawn misses early-season water, so aim for that window and schedule in advance.
The most common cause is freeze damage a cracked pipe, valve, or backflow device but it can also be the controller, a power or wiring issue, or a stuck valve or solenoid. If your system won’t start or a zone won’t fire this spring, it’s worth diagnosing before peak watering rather than forcing it. We can find and fix the cause fast.
You can, but there’s real risk in doing it wrong. Opening the water too fast causes water hammer that can crack pipes and fittings, and a quick DIY startup often misses the freeze-damaged heads and lines that then waste water all summer. A professional turn-on charges the system safely, inspects every zone, and catches problems early.
We slowly re-pressurize your system, run and inspect every zone, check and adjust each head for coverage, look for leaks and winter damage, reset your controller for the season, and confirm your backflow device is working. You get a fully tested, ready-to-water system and a heads-up on any repairs it needs.
It depends on the size of your system and how many zones it has. A standard turn-on is a flat service call; if we find winter damage that needs repair, we’ll quote that separately before doing any work. Call (913) 829-4949 for pricing on your system.
