Nine Months Later: What Ian Taught Us

It has been nine months since Hurricane Ian devastated Southwest Florida, and as we enter the 2023 hurricane season, the lessons from that storm are still fresh in our minds. For Bradenton and Manatee County, Ian was a wake-up call. While we were spared the worst of the storm surge that obliterated parts of Fort Myers and Lee County, we experienced significant flooding, extended power outages of three to seven days, and widespread plumbing failures that kept Rosco Plumbing and every other plumber in the county running at full capacity for months.

The most important lesson from Ian is one that emergency management professionals have been saying for years: the time to prepare is before the storm, not during it. The homes that weathered Ian with minimal plumbing damage were overwhelmingly the ones that had invested in resilience upgrades and maintenance before the storm arrived. The homes that suffered the most severe damage were the ones with deferred maintenance, aging pipes, and vulnerable water heater installations.

As we head into the 2023 season, this guide revisits the specific lessons learned from Ian and provides a clear action plan for Bradenton homeowners who want to be better prepared this time around. We are not trying to scare anyone — we are sharing what we saw and what we learned, so you can take practical steps to protect your home.

Lesson 1: Water Heaters Are the Most Vulnerable Appliance

In the weeks after Ian, water heater replacement was our single highest-volume service. Dozens of water heaters across Manatee County were damaged or destroyed by floodwater, and many more were compromised by extended power outages. The pattern was consistent: homes that had water heaters sitting on the garage floor suffered damage with as little as three to four inches of flooding. Gas water heaters were the most dangerous — floodwater contamination of the gas valve created a safety hazard that required complete replacement.

The lesson is clear: if your water heater is in a location vulnerable to flooding (on the garage floor, in a low-lying utility room, or in any area below the base flood elevation), it needs to be elevated or replaced with a wall-mounted unit. Since Ian, we have elevated dozens of water heaters onto raised platforms and converted many homes to wall-mounted tankless units. These are no longer theoretical safety upgrades — they are proven protections against a scenario that already happened once and will happen again.

The extended power outage also taught us about the bacterial risk in stagnant water heater tanks. Several Bradenton homeowners reported illness symptoms consistent with Legionella exposure in the days after power was restored and they resumed using hot water that had been sitting stagnant and cooling for days. The takeaway: after any extended power outage, heat the tank to maximum temperature and flush it completely before using hot water for bathing or other exposure.

Lesson 2: Pressure Surges When Water Service Returns

One of the most unexpected sources of plumbing damage from Ian was not the storm itself — it was the restoration of water service afterward. When Manatee County Utilities brought the water distribution system back online in stages, the pressure fluctuations caused a wave of plumbing failures throughout the county. Polybutylene fittings blew out, old gate valves failed, and supply line connections that had been marginally holding for years gave way under the surge.

We responded to multiple calls on the same days that water service was restored to different neighborhoods — homeowners who had ridden out the storm without any plumbing problems suddenly had water spraying from behind walls or under sinks because the pressure surge overwhelmed weakened connections. The homes most vulnerable to this were those with polybutylene pipes, galvanized pipes, and old rubber supply lines.

The preventive measures are straightforward: if you know a water service restoration is coming after an extended outage, close your main shutoff valve before the service comes back on. Once the municipal pressure has stabilized (wait 15 to 30 minutes), slowly open your main valve and check all fixtures for leaks. This controlled approach lets you detect problems before the full system pressure is applied throughout the house. And if you have polybutylene pipes, this is yet another reason to get them replaced before the next storm season.

Rosco's Tip: The Controlled Restart

After any extended water outage, use this restart sequence: (1) Close your main shutoff valve, (2) Close all faucets and fixture valves, (3) Wait for municipal pressure to stabilize, (4) Slowly open the main valve halfway and listen for leaks, (5) Walk through the house checking all visible connections, (6) Open the main valve fully only after confirming no leaks. This takes ten minutes and prevents the kind of sudden pressure-surge failures we saw all over Manatee County after Ian.

Lesson 3: Sewage Backup Was Widespread

The sewage backup problem during and after Ian was worse than many people expected. Manatee County's sanitary sewer system was overwhelmed by the volume of stormwater infiltration, and raw sewage backed up into homes through floor drains, shower drains, and toilet bowls across the county. This was not limited to low-lying areas — even homes in neighborhoods that rarely see flooding experienced backup because the entire municipal system was over capacity.

The homes that escaped sewage backup were disproportionately the ones with backwater valves installed on their sewer laterals. This simple, relatively inexpensive device proved its worth many times over during Ian. A backwater valve costs $800 to $1,500 to install, while a sewage backup cleanup and remediation costs $10,000 to $30,000 or more — not to mention the health hazard and the emotional toll of having raw sewage in your home.

Since Ian, we have installed more backwater valves in six months than we did in the previous five years combined. The demand has been driven by homeowners who experienced backup firsthand and by those who saw their neighbors deal with it and decided to protect their own homes proactively. If you do one single plumbing upgrade before the 2023 hurricane season, make it a backwater valve. The return on investment when it is needed is nearly infinite.

Lesson 4: Insurance Has Changed — Permanently

Hurricane Ian was a $110 billion insurance event — one of the costliest natural disasters in American history. The impact on Florida's already-fragile insurance market has been seismic. Since Ian, several more Florida insurance companies have become insolvent or withdrawn from the market. Citizens Property Insurance Corporation — the state-run insurer of last resort — has grown to over 1.3 million policies, making it the largest property insurer in the state. Premiums across the board have increased dramatically, with some Manatee County homeowners seeing 30 to 50 percent increases at renewal.

In this environment, insurance companies are scrutinizing plumbing systems more aggressively than ever. Polybutylene piping, galvanized piping, water heaters over 15 years old, and lack of backwater valves are all items that can trigger non-renewal, coverage exclusions, or significant premium increases. Some insurers are now requiring a four-point inspection that includes a plumbing evaluation before they will issue or renew a policy.

The practical implication for Bradenton homeowners is clear: maintaining and upgrading your plumbing system is no longer just about avoiding emergency repairs — it is about maintaining your ability to insure your home at reasonable rates. A documented repipe, a new code-compliant water heater installation, and a backwater valve certification all strengthen your insurance profile. Rosco Plumbing provides comprehensive documentation for every project that can be submitted to your insurer as evidence of upgrades and compliance.

Your 2023 Hurricane Season Action Plan

Based on everything Ian taught us, here is a prioritized action plan for Bradenton homeowners heading into the 2023 hurricane season. We have organized it by priority level so you can address the most critical items first, even if you cannot do everything before June 1st.

Priority one — do immediately: Test your main water shutoff valve (can you turn it? does it fully stop water flow?), locate your sewer cleanout, verify your water heater is elevated above flood risk or plan to elevate it, and replace any rubber supply lines under sinks and at the water heater with stainless steel braided lines. These items are all achievable in a single day and protect against the most damaging scenarios.

Priority two — do before hurricane season: Install a backwater valve if you do not have one, repipe if you have polybutylene, and have your water heater inspected (including anode rod check). These are bigger projects that require planning and scheduling, but they address the vulnerabilities that caused the most damage during Ian.

Priority three — do this year: Consider a smart water leak detection system, upgrade old gate-style shutoff valves to quarter-turn ball valves, inspect your sewer lateral with a camera, and sign up for a plumbing maintenance plan for ongoing protection and priority scheduling during emergencies. These are long-term resilience improvements that pay dividends every day, not just during storms.

Community Preparedness: Strength in Numbers

One encouraging development we have seen since Ian is an increase in community-level preparedness across Manatee County. HOAs in communities like Del Webb, Heritage Harbour, Greenfield Plantation, Tara, Peridia, and River Strand have organized informational sessions about plumbing resilience. Several communities have negotiated group pricing for backwater valve installations and repiping, which reduces the per-home cost and makes these upgrades more accessible for residents on fixed incomes.

If your community has not yet organized around hurricane plumbing preparedness, consider raising it with your HOA board. Rosco Plumbing is happy to present at community meetings — we have done this for several Bradenton communities and the feedback has been overwhelmingly positive. We explain the specific vulnerabilities, show real examples from Ian, and answer questions about costs, timelines, and insurance implications. There is no charge for these presentations, and we find that well-informed communities make better decisions.

We also encourage neighbors to coordinate on plumbing upgrades. When multiple homes on the same street schedule repipes or backwater valve installations in the same timeframe, we can work more efficiently and pass along savings. After Ian, we did several "block upgrade" projects where five or six neighbors all scheduled backwater valve installations in the same week, and the per-home cost was about 15 percent less than individual scheduling.

Hurricane Ian was a painful lesson, but it does not have to be a lesson learned in vain. Every upgrade you make, every vulnerability you address, every piece of deferred maintenance you finally tackle — it all adds up to a home that is genuinely more resilient when the next storm comes. And in Florida, the next storm always comes. Rosco Plumbing has been here since 1983, through every storm that has threatened Manatee County.
