Preparing Your Oahu Home’s Plumbing for Hurricane Season
Introduction
Living in paradise comes with its challenges — and hurricane season in Oahu is one of them. From June to November, island homeowners need to stay vigilant against high winds, heavy rainfall, and power outages. But while most people focus on securing windows and roofs, your home’s plumbing system also needs protection.
At Hawaii Plumbing & Drain Cleaning Squad, we know how Oahu’s unique environment — salty air, aging infrastructure, and high humidity — makes plumbing systems vulnerable during storms. Taking steps now can save you from costly water damage, contamination, and service outages later.
Here’s how to prepare your plumbing for hurricane season and keep your home safe, dry, and functional when the storms roll in.
1. Inspect and Clear Your Drains and Gutters
Why it matters:
Blocked drains and gutters can’t handle heavy rainfall and quickly lead to backups, flooding, and roof damage during a hurricane.
What to do:
- Clear debris, leaves, and sediment from all gutters, outdoor drains, and downspouts.
- Make sure exterior drainage systems direct water away from your home’s foundation.
- For ground-level drains, remove any obstructions that could prevent water flow.
DIY or Call Us?
You can handle surface-level cleaning, but if you notice slow drains or frequent backups, call our team. We’ll inspect and clear your pipes with high-pressure water jets to prevent future blockages.
2. Shut Off the Main Water Valve Before the Storm Hits
Why it matters:
If a storm damages your plumbing or a pipe bursts or leakage, the main shutoff valve is your first line of defense to stop flooding.
What to do:
- Locate your main water shutoff valve — usually near the perimeter of your home or meter box.
- Test it in advance to ensure it turns out smoothly.
- If a hurricane warning is issued, shut it off before the storm hits.
DIY or Call Us?
If you can’t locate or turn the valve, give us a call. We’ll show you how to operate it and can replace it if it’s stuck or corroded.
3. Secure Outdoor Plumbing Fixtures and Hoses
Why it matters:
High winds can whip around unsecured hoses or fixtures, causing damage to your home or tearing connections loose.
What to do:
- Disconnect garden hoses and drain them.
- Cover or insulate outdoor faucets and hose bibs.
- Anchor or store any exposed plumbing equipment (such as irrigation controls or filters).
DIY or Call Us?
This is a simple DIY job, but for homes with outdoor kitchens, water heaters, or custom irrigation, we can help secure and weatherproof the setup.
4. Install a Sewer Backflow Valve
Why it matters:
Oahu homes near the ocean or with older sewer lines are especially vulnerable to sewer backups during flooding.
What to do:
DIY or Call Us?
This must be installed by a licensed plumber. If your neighborhood has a history of flooding or you're in a low-lying area, call us to evaluate your risk.
5. Check Your Sump Pump or Install One
Why it matters:
Sump pumps prevent water from pooling in basements or crawl spaces during flash floods or rising groundwater.
What to do:
- Test your pump by pouring water into the basin and making sure it activates.
- Install a battery backup in case of power outages.
- If you don’t have a sump pump but your home floods easily, consider installing one.
DIY or Call Us?
Maintenance like cleaning and testing can be DIY. For installation or repairs, our team offers sump pump solutions designed for Hawaii’s climate.
6. Protect Your Water Heater
Why it matters:
Your water heater could shift or become damaged during flooding, resulting in leaks or total failure.
What to do:
- Ensure it is securely anchored, especially if you live in a flood-prone zone.
- Elevate the unit slightly if it’s located in a low-lying area.
- Consider a tankless water heater to reduce flood risk and save energy.

7. Schedule a Full Plumbing Inspection Before the Season Peaks
Why it matters:
Hidden leaks, corroded pipes, or weak joints can turn into disasters during storms. An inspection can catch these issues early by the help of emergency plumbing services.
What to do:
Schedule a comprehensive plumbing checkup, including:
- Leak detection
- Pipe integrity testing
- Sewer camera inspection
- Drain and valve function test
Island Insight: Why Oahu Homes Need Extra Plumbing Protection
Oahu’s tropical storms bring more than rain — salt air accelerates corrosion, older homes have aging plumbing, and high humidity encourages mold after even minor leaks. Add to that the chance of power outages and sewage backups, and it becomes clear why plumbing prep should be part of your hurricane plan.
Proactive maintenance can save thousands of dollars and protect your home and family from storm-related plumbing failures.
