Hurricane Plumbing Prep: Protecting Your Pipes in Charleston

Hurricane season in Charleston runs from June through November, with peak activity typically occurring between August and October. Proper plumbing preparation can mean the difference between minor inconvenience and catastrophic water damage to your home.

As a Charleston homeowner, you understand that hurricanes aren't just a possibility—they're an annual reality. From Hurricane Hugo in 1989 to more recent storms like Hurricane Matthew and Hurricane Dorian, Charleston has weathered numerous powerful storms. Each hurricane brings unique challenges for your home's plumbing system.

Pre-Season Plumbing Preparation

Hurricane preparation should begin well before any storm is on the horizon. Early preparation allows you to address issues methodically and ensure your plumbing system is ready for whatever nature brings.

Annual Plumbing Inspection

Schedule a comprehensive plumbing inspection each spring:

• Pipe condition assessment: Check for corrosion, leaks, or weak joints
• Sump pump testing: Ensure your pump is operational and properly maintained
• Drainage system evaluation: Clear debris from gutters and storm drains
• Water heater inspection: Check for proper installation and safety features
• Shut-off valve testing: Ensure all valves operate smoothly

Sump Pump Preparation

In Charleston's low-lying areas, sump pumps are essential for flood protection:

• Test monthly: Pour water into sump pit to ensure pump activates
• Clean intake screen: Remove debris that could clog the pump
• Check power supply: Test backup power sources
• Inspect discharge pipe: Ensure it directs water away from foundation
• Consider battery backup: Power outages are common during storms

72-Hour Storm Preparation

When a hurricane threatens Charleston, you have approximately 72 hours to complete your plumbing preparations:

Water Supply Preparation

Ensure access to clean water during and after the storm:

• Fill bathtubs: Store water for non-drinking uses
• Store drinking water: One gallon per person per day for at least 3 days
• Fill water containers: Use clean containers for additional storage
• Ice preparation: Freeze water in containers for cooling and drinking

Shut-Off Valve Preparation

Know how to quickly shut off water to prevent damage:

• Locate main shut-off: Usually near the water meter at the street
• Test valve operation: Ensure it turns smoothly
• Mark valve location: Use bright tape or paint for easy identification
• Keep tools handy: Water meter key or adjustable wrench
• Teach family members: Everyone should know the location and operation

Appliance Protection

Protect water-using appliances from potential damage:

• Disconnect appliances: Unplug washers, dishwashers, and other units
• Move appliances: Elevate units from basement or ground level if possible
• Shut off individual valves: Turn off water supply to each appliance
• Drain water lines: Remove residual water from appliance lines

Evacuation Preparation

If you must evacuate, proper plumbing shutdown is crucial:

Water System Shutdown

Complete these steps before leaving:

• Turn off main water supply: Prevent flooding if pipes burst
• Shut off water heater: Gas and electric units should be turned off
• Drain pipes: Open faucets to drain remaining water
• Add antifreeze: To toilet bowls and sink traps (non-toxic RV antifreeze)
• Disconnect utilities: Turn off electricity to water-related systems

Documentation

Prepare important documents before evacuating:

• Insurance policies: Homeowner's and flood insurance information
• Plumbing photos: Document current condition of plumbing systems
• Serial numbers: Record appliance and water heater serial numbers
• Plumber contact: Have your preferred plumber's contact information

During the Storm

Once the hurricane arrives, your preparation pays off:

Monitoring Your System

Stay alert to plumbing issues during the storm:

• Check for leaks: Inspect visible pipes and fixtures regularly
• Monitor water pressure: Changes may indicate system problems
• Listen for unusual sounds: Gurgling or rushing water sounds
• Watch for backup: Monitor drains and toilets for sewage backup

Emergency Actions

If problems arise during the storm:

• Shut off water immediately: If major leaks occur
• Document damage: Take photos for insurance claims
• Contain water: Use towels, buckets, or tarps to limit damage
• Avoid electrical hazards: Don't touch electrical equipment near water

Post-Storm Assessment

After the storm passes, systematic assessment is crucial:

Initial Safety Check

Before turning water back on:

• Check for gas leaks: Smell for gas around water heater and appliances
• Inspect electrical systems: Ensure no water damage to electrical components
• Look for structural damage: Check for foundation or wall damage
• Examine visible pipes: Look for obvious breaks or damage

Water System Restoration

Restore your water system gradually:

• Turn on main water slowly: Allow system to pressurize gradually
• Check for leaks: Inspect all visible pipes and joints
• Test water quality: Run water until it runs clear
• Flush hot water system: Clear sediment from water heater
• Restart appliances: One at a time, checking for proper operation

Common Storm-Related Plumbing Issues

Understanding common problems helps you identify and address issues quickly:

Flood Damage

Flooding is the most common plumbing-related storm damage:

• Sewage backup: Overwhelmed systems can back up into homes
• Contaminated water: Floodwater can contaminate your water supply
• Appliance damage: Water-damaged appliances may need replacement
• Pipe damage: Shifting soil can break underground pipes

Wind Damage

High winds can cause indirect plumbing damage:

• Roof damage: Can lead to water intrusion and pipe damage
• Debris impact: Flying debris can damage exterior pipes
• Power outages: Affect sump pumps and water heaters
• Tree damage: Fallen trees can break underground utilities

Pressure Changes

Hurricanes can affect water pressure systems:

• Well pump problems: Power outages affect private wells
• Municipal supply issues: Treatment plants may be affected
• Pressure tank damage: Wind or flood damage to pressure systems
• Pipe bursts: Sudden pressure changes can burst weakened pipes

Charleston-Specific Considerations

Charleston's unique geography and climate create specific challenges:

Tidal Flooding

Charleston's coastal location means storm surge is a major concern:

• King tide timing: Hurricanes during high tide periods are especially dangerous
• Drainage system overload: Storm drains can't handle combined rainfall and surge
• Saltwater intrusion: Saltwater can damage pipes and appliances
• Foundation undermining: Tidal action can affect foundation stability

Historic Home Challenges

Charleston's historic homes face unique storm-related issues:

• Raised foundations: Older homes may have vulnerable underfloor plumbing
• Antique systems: Older plumbing may be more vulnerable to storm damage
• Preservation concerns: Repairs must consider historic value
• Access challenges: Older homes may have difficult-to-reach plumbing

Emergency Supplies Checklist

Keep these plumbing-related emergency supplies on hand:

Basic Tools

• Adjustable wrench (for shut-off valves)
