Hurricane Season Plumbing Checklist for Southwest Florida Homeowners

Southwest Florida homeowners prepare for hurricane season by stocking water, fueling generators, and closing shutters. Plumbing usually gets left off the list — right up until the power goes out, the well pump stops, or a storm surge pushes sewage back up a drain. This hurricane season plumbing checklist covers what to do before a storm, during an outage, and after the water recedes.

Atlantic hurricane season runs June 1 through November 30, and the SWFL peak lands in August through October. The best time to work this list is a quiet weekend well ahead of a named storm.

Before the Storm

Find and test your main water shut-off. Every adult in the house should know where it is and be able to close it. If the valve is seized, corroded, or you cannot find it at all, fix that before June — not while water is spraying. Our guide to shutting off the water walks through locating it.
Clear drains and gutters. A slow drain is a backed-up drain once eight inches of rain arrives. Address sluggish fixtures with professional drain cleaning rather than waiting.
Know your sewer line’s condition. Roots or a partial collapse turn heavy rain into a backup inside the house. A video camera line inspection shows what is actually down there.
Check your lift station and backflow device. Low-lying SWFL properties depend on lift stations to move wastewater. Confirm alarms work and know whether yours has generator backup. Utilities require periodic backflow prevention testing; a storm is a poor time to discover the device has failed.
Store drinking water. Plan on one gallon per person per day for at least a week. Well owners should store more — no power means no pump.
Secure and photograph. Bring loose items indoors and photograph your water heater, treatment equipment, and exposed plumbing. Dated photos make insurance claims far easier.

When a Storm Is Inbound

Fill bathtubs and containers for flushing and washing. If you are evacuating, shut off the main water valve and turn off the water heater — an electric unit that runs dry can destroy its elements, and a leak in an empty house runs unnoticed for days. Well owners should shut off power to the pump so it does not cycle on dirty or air-filled lines.

After the Storm

Respect boil-water notices. Utilities issue them when pressure loss may have let contaminants into the mains. Follow the notice until it is formally lifted.
Test well water after flooding. Floodwater carries bacteria, fuel, and agricultural runoff, and a flooded wellhead can contaminate the aquifer supply your family drinks. Do not assume clear water is safe — see 5 Signs Your Well Water Needs Treatment.
Restore water slowly. Reopen the main valve gradually and run cold taps first to clear air and sediment, which protects aerators, fixtures, and treatment media.
Inspect for damage. Check under sinks, around the water heater, and at the meter for new drips. A high bill after a storm often means a hidden leak — the situation we covered in High Water Bill or City Leak Notice.
Have submerged equipment evaluated. Water heaters, well pumps, and treatment systems that went underwater generally need professional inspection or replacement, not a simple reset.

A Note for Snowbirds and Seasonal Owners

If your SWFL home sits empty through hurricane season, shut off the main valve and the water heater before you leave, and arrange for someone local to check the property after a storm. An unattended failure has months to do damage.
