When the Middle Tennessee weather finally turns warm, it's tempting to flip your irrigation system back on and forget about it. But rushing the spring start-up is one of the most common ways homeowners end up with cracked pipes, broken heads, and uneven coverage. A careful activation gets your lawn greening up evenly and catches small problems before they cost you.
Start by recharging the system slowly. Water left in the lines over winter — and any air in the pipes — needs to be released gradually. Opening the main valve too fast creates a pressure surge (called water hammer) that can crack fittings and blow out sprinkler heads. Open it slowly and let the system pressurize over a couple of minutes.
Next, run each zone one at a time and watch closely. Look for heads that won't pop up, spray patterns aimed at the driveway instead of the lawn, misting (a sign of pressure that's too high), and any low or soggy spots that hint at a leak underground. Winter freezes can shift and crack components, so this zone-by-zone inspection is the heart of a good start-up.
Finally, reprogram your controller for the season. Early spring lawns need far less water than the peak of summer, and overwatering now invites disease and wasted money. Set a sensible schedule and plan to adjust it as temperatures climb.
If any of this feels like more than you want to take on, that's exactly what we're here for. Our spring activation service handles the whole checklist — a slow recharge, a full inspection, spray adjustments, and controller programming — so your system is ready for the season with no guesswork.
