Before a storm hits, you’ll shut off and label the main water valve and any outdoor shutoffs, then open faucets to drain lines and disable the water heater. You’ll disconnect, drain, and store hoses, repair leaky hose bibs, and cap them with insulation. You’ll confirm drains and gutters are clear and check sewer cleanouts. For flood or hurricane risk, you’ll test or add a code-approved backflow preventer and protect sump pumps and exposed piping. More steps are just ahead.
Shut Off Main Water and Outdoor Faucets
First, shut off your main water supply and secure any outdoor shutoff points before the storm hits, because uncontrolled water pressure and freezing lines can turn a small leak into major structural damage. Burst pipes can release over 400 gallons of water per hour, so acting quickly can dramatically limit flooding and water damage. Find the main valve where the service line enters the house, typically at the meter, basement, or crawl space; if you’re unsure, trace the pipe from the water meter. If the shutoff is in a street-side meter box, lift the cover with a screwdriver and use a T-handle key.
Identifying your home’s vulnerability to water intrusion is crucial in storm preparation. Identify the valve type before you operate it. Turn a gate valve’s round wheel clockwise with steady pressure until it stops; don’t crank brittle older stems. Rotate a ball valve lever 90 degrees so it’s perpendicular to the pipe. If it’s seized, don’t force it—use penetrating oil and wait or call a licensed plumber.
After shutdown, open faucets to drain lines, and disable the water heater. Mark and label shutoffs.
Secure Hose Bibs, Sprinklers, and Loose Hoses
Before the storm drives temperatures down or whips debris across your yard, secure every exterior hose bib, sprinkler connection, and loose hose because trapped water and wind load can crack fittings and flood wall cavities during thaw. Inspect each hose bib: look for corroded nuts, worn washers, and broken seals, and replace parts immediately. Confirm the handle operates fully; rusted stems can prevent shutoff. If a shutoff valve seeps, pressure can still reach the spigot and leak when freezing loosens seals. Additionally, understanding your home’s plumbing systems can help you identify issues early.
Disconnect every garden hose from the bib to eliminate freeze-pressure backup. Drain hoses completely, roll them to purge low spots, and store them indoors in a dry area. Cap or cover bibs with foam or hard covers, or use an insulated bag tightened securely; improvised wraps (rags plus plastic and tape) must form a tight, weatherproof barrier. Add foam insulation or heat tape to exposed supply piping where permitted.

Test (or Add) a Backflow Preventer Before Hurricanes
Once you’ve secured exterior hose bibs and irrigation connections, address the bigger flood-path risk inside: sewer backflow during hurricane rain and storm surge. A backflow preventer lets wastewater drain out but blocks reverse flow, limiting contamination and flood damage—especially if your lowest drains sit below your Base Flood Elevation (BFE).
Backflow prevention devices help stop stormwater or sewage from flooding buildings through drains.
Inspect floor drains, standpipes, and the building sewer for an existing device, then verify it operates before hurricane season. Check valve-style units provide basic protection; a gate valve adds manual shutoff for service; a dual backflow valve (check + gate) gives the most robust closure. Confirm the valve matches pipe size, is installed at an approved location on the sewer line or floor drain, and remains accessible for inspection. Use an O-ring expander only if it’s listed for that application.
Test by filling the upstream drain with water and confirming the seal holds; then relieve trapped air between the P-trap and preventer. Call your local building official for permit and code requirements.
Clear Gutters, Drains, and Sewer Cleanouts
While you’re focused on keeping wastewater from backing up, you also need a clear path for rainwater to leave the building site: clean out gutters, downspouts, yard drains, and sewer cleanouts now—not when the storm bands arrive. Clogged gutters can cause flooding, foundation damage, and costly repairs. Schedule cleaning at least once or twice yearly (spring and fall), and tighten it to bi-monthly checks if you’ve got heavy tree cover or frequent severe weather.
Remove leaves and grit before they mat and dam flow; even a small handful can start overflow. Confirm water runs through downspouts, not over the gutter edge, which soaks siding, windows, and foundations and can drive settlement and basement flooding. Inspect fasteners, brackets, and joints so wind and debris can’t rip loaded gutters loose. If you wash, keep pressure low (about 1,200–1,500 PSI) to avoid damage. Use licensed, insured pros for twice-yearly inspections or after major storms.
Protect Water Heaters, Sump Pumps, and Exposed Pipes
If rising water, wind, or a power outage hits your property, protect the plumbing equipment that fails fast and expensively: water heaters, sump pumps, and exposed piping. In flood zones, elevate your water heater at least 1 foot above the Base Flood Elevation (BFE) on a rated platform or solid blocks, and keep combustion air and venting code-compliant. Brace the tank to wall framing with heavy-gauge metal strapping at the top and bottom using 3-inch lag screws; add wood blocking where gaps exceed 1–2 inches so straps can’t slacken. Before a storm, deploy ICC-listed PVC flood covers or build a concrete floodwall when expected depths stay under 3 feet. Add an electronic flood-stop shutoff on the cold supply line; sensors close the valve automatically. If flooding is imminent, shut off gas or power, close the main valve, and open the farthest faucet to relieve pressure. Protect exposed pipes with insulation and secure supports. Install flexible connectors with enough slack on water, gas, or electric lines to withstand significant tremors. Additionally, consider emergency supply kits that include items specifically designed to assist with plumbing protection during severe weather events.
Frequently Asked Questions
What Emergency Plumbing Supplies Should I Keep on Hand Before a Storm?
Keep a basic plumbing toolkit (pipe/basin wrench, pliers, screwdrivers), a cup and flange plunger, and a hand auger. Stock plumber’s tape, plumber’s putty, temporary pipe clamps/repair tape, buckets, and towels. Add rubber gloves, pipe insulation, disinfectant, and a wet/dry vacuum. You must know your main and fixture shut-offs, and you’ll shut off power at the breaker if water nears outlets. Keep a plumber’s number handy.
How Can I Tell if My Home’s Pipes Are Too Old for Storm Conditions?
You can tell your pipes are too old when “quiet” looks safe but hides brittle, cracked lines. Check materials: clay at 50–60 years and cast iron at 75–100 often near failure; joints fail first. Watch for beige/yellow stains, mold smells, warped floors, or wall/foundation cracks. Note slow drains, pressure swings, gurgling, banging, or bill spikes. Outside, flag soggy green patches, corrosion, roots, or sewer odors.
Should I Schedule a Pre-Storm Plumbing Inspection, and What Does It Include?
Yes—you should schedule a pre-storm plumbing inspection to reduce burst, backup, and flood risks. You’ll get water-supply checks for pressure, pipe condition, and working shut-off valves. You’ll get drainage checks for blockages and leaks in drains, vents, and sewer lines. You’ll have fixtures and appliances tested for flow and leaks. You’ll have the water heater inspected (TPR valve, corrosion, sediment). You’ll also test sump pumps, gutters, hose bibs, and exposed pipes.
What Signs of Hidden Water Damage Should I Check for After the Storm?
Check for discoloration, check for distortion, check for odor. Look for yellow/brown water rings, bubbling paint, or faint tracks under windows. Press drywall; if it feels soft or spongy, you’ve got saturation. Watch for sagging ceilings, warped walls, or baseboards swelling or pulling away. Sniff for musty smells, note fogging windows or RH above 55%. Inspect attic insulation, crawlspaces, and basements for pooling, stains, rust, or efflorescence.
Will My Homeowners Insurance Cover Storm-Related Plumbing and Sewer Repairs?
Yes, you’re typically covered for storm-related plumbing repairs only when damage is sudden and accidental, like a burst or frozen pipe. Your policy usually pays for resulting water damage to the dwelling and contents. You won’t get coverage for gradual leaks, wear, or neglected maintenance. Sewer or sump backups often require a specific endorsement. Flooding, storm surge, and surface runoff need separate flood insurance coverage.
