Orlando does not sit directly on the coast, but it is well within the path of hurricanes and tropical storms that cross Florida. The city also experiences severe afternoon thunderstorms throughout the wet season and occasional winter freezes that can damage tropical landscaping and irrigation components. Preparing your sprinkler system before a storm and knowing what to do afterward protects both your investment and your water supply.
Before the Storm
The most important step is to shut off the irrigation system. If a storm is approaching, turn off the controller and, if possible, close the isolation valve that feeds the irrigation system. This prevents the system from running during or after the storm, which would waste water and could contribute to flooding. If your system has a rain sensor, confirm it is functioning. A rain sensor will not stop a system that has been left in manual mode, so check the controller settings.
Secure or remove any components that could become projectiles. Sprinkler heads are typically below grade and not a concern, but above-ground backflow assemblies, pump housings, and controller cabinets can be damaged by wind or debris. If you have a pump system, cover the pump and disconnect power. If your controller is in an exposed location, consider covering it with a waterproof bag after shutting it off.
During the Storm
Do not attempt to operate or adjust the irrigation system during a storm. Lightning strikes are common in Central Florida, and irrigation wiring is a potential path for surges. Stay indoors and leave the system alone. If power goes out, the controller will lose its schedule, but most modern controllers retain settings in memory.
After the Storm
Once the storm has passed, inspect the system before turning it back on. Look for visible damage. Fallen limbs can crush lateral lines, and standing water can hide broken heads. Check the backflow assembly for damage. Check the controller for water intrusion. If anything looks damaged, do not energize the system. Call a licensed irrigation contractor for an inspection.
If the system appears intact, turn it back on one zone at a time and walk the property. Look for geysers, soggy patches, and heads that are not popping up. Storm-related repairs are one of the most common calls we receive. Our sprinkler repair guide covers typical problems and costs.
Lightning Damage
Central Florida is known as the lightning capital of the United States. A nearby strike can damage the controller board, the wiring, or the valves. If your system does not respond after a storm, lightning is a likely cause. Controller replacement typically costs $150 to $500 installed. Our article on smart controllers covers upgrade options that include surge protection features.
Freeze Events
Central Florida occasionally experiences hard freezes, usually in January or February. A freeze can damage backflow assemblies, above-ground piping, and pump systems. Before a forecast freeze, shut off the irrigation system, drain the backflow assembly if it is above ground, and protect exposed components with insulation. Tropical plants in the landscape benefit from being watered deeply before a freeze, but this should be done well before temperatures drop, not during the freeze. Our maintenance checklist includes freeze preparation as a seasonal item.
Flooding and Drainage
Orlando’s sandy soil drains quickly, but prolonged heavy rain can still cause localized flooding, especially in low areas. An irrigation system that continues running during saturated conditions can worsen the problem. If your property is prone to standing water, consider a rain sensor with a lower threshold or a smart controller that accounts for recent rainfall. Our article on Orlando’s sandy soil explains how drainage works in this region.
Planning Ahead
The best storm preparation is a system that is already in good condition. A system with cracked pipes, failing valves, or a damaged controller is more vulnerable to storm damage. Following the seasonal maintenance schedule in our Orlando irrigation maintenance checklist reduces the risk. And if you are considering a system upgrade, ask about surge protection and freeze-rated components. Our guide on sprinkler installation cost covers the options.
