Snowbird Sprinkler Checklist: Before You Head North

September 24, 2026

Every spring, the same conversation happens across The Villages: a homeowner packing up for a summer up north asks whether they should just shut the sprinklers off while they’re gone. The honest answer is no, and the reasoning is worth understanding, because the instinct to “turn everything off before you leave” is exactly backwards for an irrigation system.

Why shutting it down is the wrong move

An RV or a house’s plumbing gets winterized before a long absence because the risk is freeze damage to standing water in a system that has no reason to run while you’re gone. A sprinkler system is the opposite case entirely: your lawn is a living thing that needs water on a schedule whether you’re home or not, and Florida’s summer heat doesn’t take a break just because you have. Shutting the system off for the whole season all but guarantees you come back to dead turf, and possibly an HOA or CDD notice about lawn condition on top of it.

The real risk with an irrigation system left running unattended isn’t that it runs. It’s that something fails while it’s running and nobody notices for weeks.

The two failures that actually cost you

A stuck-open valve. If a zone valve fails in the open position, or a valve isn’t fully closing, that zone can run far more than its scheduled cycle, sometimes continuously, for as long as nobody catches it. On a metered water system, that shows up as a water bill you don’t see until you’re already home in the fall, sometimes dramatically higher than a normal month. On a non-potable irrigation system it’s less of a cost issue but still a real waste, and it can also cause its own damage: a soggy patch that drowns turf just as effectively as a dry one kills it.

A rain sensor stuck in the wrong position. A sensor stuck “dry” means the system keeps running its full schedule through actual rainfall all summer, overwatering the whole property for months. A sensor stuck “wet” is the opposite problem: it silently stops the entire system, and you come home in the fall to a lawn that got zero water for however long the sensor had been stuck, which is arguably the worse outcome of the two, since dead grass from underwatering doesn’t recover as fast as grass recovering from a few weeks of overwatering.

Both of these are exactly the kind of failure that a system left running unattended is vulnerable to, and neither one announces itself the way a completely dead zone does. The system looks like it’s working the whole time.

The checklist

1. Book an inspection one to two weeks before you leave, not the day before. That gives time to actually fix anything found, rather than leaving a known problem running for the whole season because there wasn’t time to address it.

2. Every zone gets run and watched. Not just checked on paper, actually run and observed, since a valve that’s starting to fail can look fine on a quick glance and still be the one that gives out in July.

3. The valve box gets opened and checked. Standing water between cycles is the single clearest early warning sign of a valve that’s going to fail while you’re gone, and it’s often invisible unless someone actually opens the box.

4. The rain sensor gets tested both ways. Confirmed that it actually stops the system when triggered, and confirmed that it isn’t stuck in a way that would silently prevent normal watering.

5. The controller’s backup battery gets checked or replaced. A power blip during a Florida summer storm, and Central Florida gets plenty of them, can wipe a controller’s program if the backup battery has quietly died. A fresh battery before you leave means a storm-related outage while you’re gone doesn’t leave the system reverting to a factory-default schedule that has nothing to do with your assigned watering day.

6. If you have a smart controller, confirm it’s actually connected and reporting correctly before you go. A WiFi controller that’s already showing “offline” the day you leave isn’t going to fix itself while you’re gone, and you’ll have lost the one remote-monitoring advantage it was supposed to give you.

What this doesn’t replace

An inspection before you leave is not a substitute for someone physically checking the property at some point during a long absence, whether that’s a neighbor, a property manager, or a return trip partway through the summer. It’s the best single thing you can do to reduce the odds that something goes wrong in the first place, but it can’t guarantee nothing will fail three months into an unattended summer. If you have a smart controller with remote access, checking in on the app periodically is a reasonable complement, since it at least tells you the schedule is running as expected, even though it can’t see a leaking valve box the way a technician can.

The bottom line

Don’t shut the system down. Get it inspected instead: every zone, the valve box, the rain sensor, and the controller’s battery, all checked before you head north, not after something’s already gone wrong. It’s a $90 to $200 visit against the cost of a summer of unnoticed water waste or a dead lawn waiting for you when you get back.
