Hurricane Season Plumbing Guide for Sarasota Homeowners

Hurricane season runs June 1 through November 30 — and if you've lived in Sarasota for any length of time, you know that's not a theoretical risk. Hurricane Ian made landfall just south of us in September 2022 as a Category 4 storm, and Sarasota County lost water and sewer service on Siesta Key, Casey Key, and the barrier islands for days afterward. This guide covers what to do with your plumbing before a storm arrives, during the storm itself, and after — in that order.

Why Plumbing Takes a Beating During Hurricanes

Most Sarasota homeowners think about hurricane prep in terms of shutters, generators, and bottled water. Plumbing usually comes last — until it becomes the problem. Storm-related plumbing failures fall into a few predictable categories:

• Pipe breaks from structural movement or debris impact — wind-driven debris or structural shifts can crack or sever supply lines, especially where pipes transition from inside to outside the structure.
• Sewer backflow from overwhelmed municipal systems — when the storm surge and heavy rainfall hit simultaneously, municipal sewer systems can exceed capacity. If there's no backflow prevention on your lateral line, that overflow can come up through your drains.
• Flood water entering the water supply system — breaks in the municipal distribution system after a storm can allow contaminated water to enter the lines. This is why Sarasota County issues boil-water advisories after major storms.
• Water heater and appliance damage from flooding or power surges — flooded water heaters, whether gas or electric, are a post-storm issue that requires professional assessment before restart.
• Slab pipe damage from ground movement — Sarasota's sandy coastal soils can shift significantly during heavy flooding. Homes on slab foundations — which is the majority of homes here — can experience movement that stresses the copper or PEX pipes encased in the concrete.

The good news: most of this is preventable, or at least manageable, with the right preparation. Let's go step by step.

Before the Storm: What to Do When a Watch or Warning Is Issued

When Sarasota County is under a hurricane watch or warning — typically 24 to 48 hours before expected landfall — your window for plumbing preparation is open. Here's how to use it:

Step 1: Know Exactly Where Your Main Water Shutoff Is

This is not the time to discover you don't know. In most Sarasota homes, the main water shutoff valve is located in one of a few places:

• Near the water meter — typically in a small box at the curb or property line, set into the ground. Sarasota County homes usually have a meter box here. The utility-side valve belongs to the county; the customer-side valve is yours.
• At the point where the main line enters the home — often on an exterior wall in a utility area, garage, or inside a utility closet. In Southwest Florida's slab-construction homes, this is commonly on the exterior near the hose bib.
• Inside the garage — especially in homes built in the 1990s and 2000s, the main shutoff is sometimes mounted on the interior garage wall near the water heater.

Find it now. Turn it. Make sure it actually works. Older gate valves (the wheel-handle style) sometimes corrode in place and will not turn when you need them. If yours doesn't turn freely, call a licensed plumber to replace it with a ball valve — a quarter-turn ball valve is far more reliable and takes seconds to operate in an emergency.

If you evacuate, shut off the main before you leave. A pipe break in an empty home, discovered days after the storm, is one of the most expensive scenarios we see.

Step 2: Shut Off Your Water Heater

Before shutting off the main water supply, take care of your water heater:

• Electric water heater: Turn off the circuit breaker dedicated to the water heater. Running an electric water heater without water in the tank will burn out the heating element immediately — and if flood water reaches it while energized, you have an electrical hazard.
• Gas water heater: Set the gas valve to the "off" or "pilot" position. Do not attempt to relight until you have confirmed the water supply is restored, the lines are intact, and there is no gas odor.

A tank water heater holds 30 to 80 gallons of clean water. In the aftermath of a storm, before the municipal supply is restored, that tank is a genuine emergency water resource — provided it wasn't flooded or contaminated. Keep that in mind as you make decisions about post-storm restart.

Step 3: Shut Off and Secure Outdoor Fixtures

Outdoor plumbing is the most exposed during a storm. Sarasota homes commonly have:

• Irrigation systems — turn off at the controller and at the isolation valve on the backflow preventer assembly. Irrigation pipes are typically shallow and vulnerable to debris impact. A running irrigation system during or after a flood can introduce contaminated water into your supply if the backflow preventer is damaged.
• Outdoor hose bibs — disconnect any attached hoses. A hose left attached to a hose bib can create a siphon path for contaminated water into your supply lines if municipal pressure drops (backflow without backflow prevention).
• Pool equipment and fill lines — shut off the pool's auto-fill valve and turn off the pool pump breaker. Pool pumps are not designed to run in flood conditions and can be damaged or become an electrical hazard.
• Outdoor shower connections — common in coastal Sarasota neighborhoods like Siesta Key, Osprey, and Nokomis. Shut off the supply valve if there is one; if the outdoor shower draws directly from the main line, it's protected when you shut the main.

Step 4: Fill Bathtubs for Emergency Water

Before shutting off the main, fill your bathtubs and any large containers with clean water. This is your emergency supply for flushing toilets if the municipal system goes down — which it can and does after major storms. Standard practice: use the bathtub water for flushing (three to four gallons per flush for a standard toilet), not for drinking, unless you have a way to treat it. Your water heater tank, if uncontaminated, is your cleaner drinking water reserve.

Step 5: Check Your Sewer Cleanout Access

Every Sarasota home has a sewer cleanout — a capped pipe, usually at grade level or slightly above, located along the sewer lateral between your home and the street. Note where it is before the storm. After flooding, sewer cleanouts are the access point plumbers use to assess lateral damage and relieve backpressure. If you don't know where yours is, look for a white or black PVC cap, often near the foundation, along the path to the street or sidewalk.

During the Storm: What You Can and Cannot Do

Once wind speeds pick up and the storm is on top of you, your options are limited by design. There is no safe reason to go outside during a hurricane to deal with plumbing. If you hear water running inside the house — a hiss, a drip, or flowing water sounds — and you haven't already shut off the main, do it now from wherever the valve is inside. Do not go into standing water to reach an exterior shutoff in the middle of a storm.

Do not use toilets or drains if the municipal sewer system appears to be backing up. Signs of backup include gurgling noises from multiple drains simultaneously, water rising in the lowest-level fixtures, or visible sewage smell from floor drains. If this happens, stop using plumbing fixtures immediately. The water column in the sewer lateral is what keeps sewer gas out of your home — if that seal is compromised by backflow, you have a health hazard to manage carefully after the storm.

After the Storm: Before You Turn Anything Back On

This is where Sarasota homeowners frequently make costly mistakes. The instinct after a storm passes is to restore normalcy as quickly as possible. With plumbing, moving too fast can turn a storm-related inconvenience into a serious repair bill — or a health hazard.

Step 1: Visual Inspection Before Restoring Water

Before you turn the main back on, walk through your home and look for:

• Any visible pipe damage — look under sinks, in utility areas, behind the water heater, and along any exposed pipe runs in the garage or utility closet
• Water stains or wet spots on ceilings, walls, or floors that weren't there before — this can indicate a pipe break that occurred during the storm
• Flood water marks on walls, particularly in areas near the water heater, irrigation equipment, or other plumbing fixtures
• Sediment or debris around drain openings, which can indicate a sewer surcharge reached your drains

If you see evidence of water intrusion from below — flood water that entered the home — do not turn on any electrical circuits in the affected areas, including water heater circuits, before an electrician assesses the situation.

Step 2: Restore Water Slowly and Check for Leaks

When you're ready to turn the main back on, do it slowly rather than opening the valve fully at once. Open the main to about halfway, then go through the house and check every accessible pipe junction, under-sink connection, and visible supply line. Listen for the sound of running water with no fixtures open — that's a leak somewhere. Then open the main fully and check again.

Step 3: Water Heater Restart — Follow the Right Sequence

Do not restore power to an electric water heater or relight a gas water heater until you have confirmed:

• The main water supply is restored and the tank is full (open a hot water faucet — once water flows, the tank is full)
• The water heater was not submerged or reached by flood water — if it was, it needs professional inspection before restart
• For gas units: there is no gas odor in the area

Running an electric water heater with an empty tank burns out the lower heating element within minutes. It's a common post-storm mistake that results in an avoidable service call. Fill the tank first, then restore power.

If your water heater was submerged during flooding, do not attempt to restart it yourself. Flood water contamination of the tank interior, burner assembly, or electrical components creates both health risks (bacterial contamination of the water) and safety risks. Have a licensed plumber assess it — in many cases, replacement is the appropriate call.

Step 4: Inspect the Irrigation System Before Restarting

Irrigation heads and shallow lateral lines are particularly vulnerable to storm damage. Before restarting your irrigation system after a hurricane:

• Walk the zones visually and look for heads that are cracked, broken off, or visibly damaged by debris
• Check the backflow preventer assembly for physical damage
• Start one zone at a time, watching for unexpected wet spots in the lawn that might indicate a broken lateral

A broken irrigation lateral running underground and undetected will show up on your next water bill as an unexpected spike — sometimes hundreds of gallons per day. Catch it now, before you reset the controller to the regular schedule.

Step 5: Watch for Delayed Slab Leak Signs

In the weeks after a significant storm, be alert for signs of slab pipe damage that may not be immediately obvious. Sarasota's sandy soils can shift during heavy flooding, and that movement can stress or crack the copper pipes embedded in concrete slab foundations. Delayed signs include:

• Warm or wet spots on tile or flooring, particularly in areas away from walls
• Sound of running water with all fixtures off
• Unexplained spike in water usage on your next bill
• Cracks appearing in floor tile or drywall that weren't there before the storm

Slab leaks are not always immediately apparent. If your home experienced significant ground saturation or flooding during the storm, it's worth having a plumber run a pressure test on your supply lines within a few weeks of the event. Catching a slab leak early is considerably cheaper than discovering it after months of water migrating beneath your foundation. Learn more on our emergency plumbing services page.

The Backflow Prevention Question

After Hurricane Ian, sewer backup was one of the most common plumbing complaints from Sarasota homeowners in low-lying areas. Areas like Gulf Gate, Fruitville, and parts of Venice that are close to water tables saw sewer systems overwhelmed by simultaneous storm surge and rainfall, driving sewage backward up residential lateral lines and into homes.

A backwater valve (also called a backflow preventer) installed on your main sewer lateral is the specific device designed to prevent this. It allows wastewater to flow out in the normal direction, but physically blocks flow from returning into the home. For homes in low-lying areas of Sarasota County — particularly those at or near sea level — this is a legitimate protective investment to discuss with a licensed plumber before next hurricane season. It is not a DIY installation; it requires cutting into the sewer lateral, which is licensed plumbing work.

Sarasota homeowners who experienced sewage backup during a storm and have not had a backwater valve installed are at risk of the same thing happening again. If that was your experience during Ian or any previous storm, consider this a high-priority item for your pre-season plumbing checkup. Contact our team to discuss your specific situation.

Preparing Month by Month: What to Do in May

The best time to address hurricane plumbing prep is May — before the season officially opens June 1, before storm watches create time pressure, and before every plumber in Southwest Florida is booked solid for post-storm work. Here's what a smart May plumbing inspection covers:

• Main shutoff valve test — verify it operates correctly; replace if it doesn't turn freely
• Water heater assessment — check age, condition, and whether the anode rod and sediment have been addressed recently
• Backflow preventer inspection — irrigation system backflow preventers are required by Sarasota County code and must be tested annually by a licensed plumber
• Sewer lateral inspection — particularly for homes built before 1990 with clay or cast iron laterals, a camera inspection every few years is worthwhile; roots in the lateral are a year-round issue but compound dramatically when storm flow saturates the ground
• Outdoor fixture condition — look for corroded or cracked hose bibs, damaged irrigation heads, and aging connections at the pool fill line

Many of these items take less than an hour for a plumber to evaluate. A pre-season inspection is far less disruptive than a post-storm emergency call, and post-storm emergency service — when every plumber in the county has a full callback list — will cost you more and take longer. Visit our Sarasota service page to schedule a seasonal plumbing assessment.

Specific Considerations for Sarasota Barrier Island Homes

Homes on Siesta Key, Longboat Key, Lido Key, and Casey Key face elevated hurricane plumbing risks for several reasons:

• Municipal water and sewer on barrier islands is supplied via buried pipelines that cross the bay or pass through pinch-point infrastructure. After Ian, Siesta Key and Casey Key lost both water and sewer service for multiple days because of breaks in these distribution lines. Homes on the barrier islands should maintain a larger emergency water supply than mainland homes — not just for drinking but for sanitation.
• Older homes on Siesta Key and Longboat Key may have galvanized or early copper plumbing that is particularly vulnerable to the combination of storm surge salt water exposure and ground movement. If your barrier island home has original plumbing and hasn't been inspected recently, this is a worthwhile priority before storm season.
• Mandatory evacuation zones on the barrier islands mean your home may be unoccupied during the storm. Shutting off the main water supply is essential before you leave — not optional. A pipe failure in an evacuated home discovered four days after a storm can cause catastrophic interior damage.

If you're in a mandatory evacuation zone, your pre-departure plumbing shutdown should be as routine as locking the door. Make it part of your go-bag protocol. Water heater service and plumbing assessments are part of what we offer to barrier island homeowners throughout Sarasota County.

One More Thing: Document Your Plumbing Before Hurricane Season

Take five minutes this spring to photograph your main shutoff valve location, your water heater serial number and model (for insurance claims), your irrigation backflow preventer, and your sewer cleanout location. Store these photos somewhere accessible — a cloud photo album, emailed to yourself, or saved on your phone. After a storm, when you're dealing with adjuster visits and contractor quotes, having documented pre-storm conditions is genuinely useful. Insurance adjusters deal with ambiguous claims constantly; clear documentation of your existing system, its condition, and its location works in your favor.

Summary: The Short Version

Before the storm: Find your main shutoff, confirm it works, shut off your water heater (breaker or gas valve), disconnect outdoor hoses, shut off irrigation, fill bathtubs, and shut the main if you evacuate.

During the storm: Don't go outside. Don't use plumbing if sewage is backing up. Shut the main from inside if you hear an unexpected leak.

After the storm: Inspect before you restore water. Restore slowly and listen for leaks. Don't restart the water heater until the tank is full and the unit wasn't flooded. Follow boil-water advisories. Watch for delayed slab leak signs in the weeks after the storm.

Hurricane preparedness is essentially about decision-making — and the best decisions are made in advance, when you have time to think clearly. If your Sarasota home has plumbing vulnerabilities going into storm season, now — not July — is the time to address them.
