Every spring in Ogden and South Ogden, thousands of homeowners turn their sprinkler systems back on after winter — and a good number of them immediately discover cracked heads, stuck valves, and leaks they didn’t know existed.
A proper spring startup takes about 30 minutes and can save you hundreds in water damage and emergency repair calls. Here’s how to do it right — or how to know when it’s time to call in a sprinkler repair professional.
When to Turn Sprinklers On in Ogden
The safe window for spring startup in Weber County is typically mid-April through early May. You’re waiting for two things: overnight temperatures consistently above 32°F, and your grass starting to green up and actively grow.
Turning the system on too early risks refreezing in the lines, especially in higher-elevation South Ogden neighborhoods around Uintah Highlands and Shadow Valley where nighttime temps drop lower than the valley floor. According to USU Extension’s irrigation guidelines, lawns in Northern Utah don’t need supplemental water until active growth begins — so there’s no benefit to rushing it.
Step-by-Step Startup Checklist
Start by opening the main shutoff valve slowly. If your system was winterized with a blowout, the lines should be empty. Opening the valve too fast can cause a pressure spike that damages pipes, fittings, and backflow preventers. Turn it a quarter turn, wait 30 seconds, then open fully.
Next, check the backflow preventer for visible cracks or leaks. Ogden’s freeze-thaw cycles are hard on these units, and a damaged backflow device can contaminate your home’s water supply.
Then run each zone one at a time from the controller. Walk the yard while each zone runs and check for heads that aren’t popping up, heads spraying in the wrong direction, water bubbling up from the ground which usually signals a sprinkler line leak, and dry spots where a head may be clogged or broken.
Finally, check the controller itself. Replace the backup battery, verify the date and time, and adjust your watering schedule for spring conditions — typically two to three days per week in April, increasing as temperatures rise.
Common Problems Found During Spring Startup
After sitting dormant through an Ogden winter, sprinkler systems commonly show cracked or shattered spray heads from foot traffic or freeze damage, stuck solenoid valves that won’t open or close, controller programming that was wiped by a dead battery, and root intrusion into drip lines — especially in older Ogden neighborhoods with mature trees.
Many of these are straightforward fixes. But if you find multiple zones with pressure issues or water surfacing in unexpected places, that usually points to a deeper problem — cracked mainline, failed valve box, or root-damaged pipes. These are covered in more detail in our guide to common sprinkler issues.
Why Spring Startup Matters for Your Lawn
Your lawn’s health through July and August depends heavily on what happens in April and May. If your system has dead zones, misaligned heads, or a slow underground leak, your grass will show it by June — brown patches, thinning areas, and uneven growth patterns that get worse as temperatures climb.
Catching problems during spring startup means your irrigation system runs efficiently from day one of the growing season. That keeps your yard green, your water bill lower, and your sod or lawn investment protected.
