Florida Winter Irrigation Checklist: Backflow Freeze Protection, 1-Day Timer Reset & Dry-Season Upgrades

When cooler temperatures and Eastern Standard Time arrive in Port Orange, Daytona Beach, New Smyrna Beach, and Ormond Beach, many homeowners assume they can ignore their sprinkler system until spring. In coastal Central Florida, however, November through February is actually the dry season—and it brings three costly hazards for your lawn and equipment: overwatering fungus, winter dry spots, and overnight backflow preventer freeze damage.

Here is the complete East Volusia County homeowner checklist to protect your irrigation system, lower your winter water bill, and take advantage of cooler weather for high-impact property upgrades.

1. Reset Your Timer for the SJRWMD 1-Day Winter Watering Schedule

From the first Sunday in November through the second Sunday in March (Eastern Standard Time), the St. Johns River Water Management District (SJRWMD) enforces a 1-day-per-week watering restriction across Volusia County:

• Odd-numbered residential addresses: Saturday only (before 10:00 a.m. or after 4:00 p.m.)
• Even-numbered residential addresses: Sunday only (before 10:00 a.m. or after 4:00 p.m.)

Leaving an older mechanical pin-timer on its summer 2-day schedule during winter not only violates local watering ordinances and inflates your utility bill, it also keeps semi-dormant St. Augustine and Zoysia turf cold and wet—the #1 trigger for Large Patch (Brown Patch) winter lawn fungus.

Conversely, if your lawn only gets watered once a week, a single clogged rotor nozzle or low-pressure zone means that section of grass goes 14+ days without water, causing rapid winter dieback in sandy coastal soil. A quick Winter System Wet-Check ensures every head pops up cleanly, rotates properly, and delivers balanced coverage on your single watering day.

2. Protect Your Backflow Preventer & Well Pump Before a 32°F Freeze

Every winter, coastal Volusia County experiences a handful of crisp 28°F to 35°F overnight freezes in December, January, and February. Because your underground PVC pipes are insulated by the earth, the most vulnerable part of your entire irrigation system is your above-ground brass Backflow Preventer (PVB or RPZ assembly) and your shallow-well irrigation pump.

When water sits trapped under pressure inside a brass pressure vacuum breaker overnight during a hard freeze, the expanding ice cracks the internal plastic poppet, warps the bonnet, or splits the brass body—resulting in a massive geyser in your front yard the moment the morning sun thaws the pipe.

How to prevent winter backflow and pump damage:

• Have leaking shutoff ball valves, weeping test cocks, or dripping backflow bonnets repaired before the first cold snap.
• Install an insulated backflow pouch or freeze blanket over above-ground PVB/RPZ assemblies and exposed well pump piping.
• Upgrade to a Smart Wi-Fi Irrigation Controller (such as Rain Bird or Rachio) or a working wireless rain/freeze sensor that automatically pauses early-morning watering when temperatures drop near freezing—preventing dangerous sheets of ice on your driveway and sidewalk.

3. Why Winter Is the #1 Time for LED Landscape Lighting (5:30 PM Sunsets)

In July, the sun doesn't set until 8:30 p.m. In November, December, and January, it is pitch black by 5:30 p.m.—right when you pull into the driveway or welcome Thanksgiving and holiday guests.

If your existing low-voltage landscape lights have burnt-out halogen bulbs, cut underground wires from summer edging, corroded sockets, or a failed dusk-to-dawn transformer, our technicians can troubleshoot and restore your system—or design a brand-new 12V LED pathway, entryway, and Canary/Sabal palm uplighting package that keeps your home warm, inviting, and secure all winter long.

4. Beat the Summer Rush with Dry-Season French Drain Installation

If your side yard, swale, or pool patio flooded during late-summer thunderstorms or tropical storms, Florida's dry winter season is the smartest time of year to install a custom French drain and catch-basin system.

• The seasonal water table is lower, allowing for cleaner, faster laser-graded trench excavation.
• Connecting roof gutter downspouts into buried solid PVC discharge lines now means your foundation and turf are 100% protected before spring and summer downpours return.
