Before a hurricane, locate and test your main water shut-off, know how to turn off your water heater, clear outdoor drains, and store drinking water. After the storm, check for leaks and sewage backups before using plumbing normally, and follow any boil-water notice from your utility.
Before hurricane season (June 1 – November 30)
- Find and test your main shut-off valve. If it’s stuck or leaking, have it replaced now. See how to shut off your water.
- Locate your sewer cleanout and make sure the cap is in place and accessible.
- Service your water heater. Know how to turn it off, check that it’s secured, and fix any small leaks. See water heater repair.
- Replace rubber washing machine hoses with braided stainless lines.
- Fix existing leaks so they don’t become bigger problems during a long power or water outage.
- Clear gutters, downspouts and yard drains so stormwater moves away from the house.
- Ask about a backwater valve if your property has had sewage backups during heavy rain.
When a storm is approaching
- Store drinking water in clean containers. Plan for several days for each person and pet.
- Fill bathtubs with water for flushing toilets manually if water service is interrupted.
- If you’re evacuating, shut off the main water valve and turn off the water heater (breaker off for electric; gas to off).
- Seasonal residents leaving the area should shut off the water and water heater and arrange for someone to check the home.
- Bring in or secure outdoor items near pipes and the water heater (if outside).
Generators and water heaters
Never run a portable generator indoors, in a garage or near windows. Carbon monoxide can be fatal. Electric water heaters draw a lot of power; if you plan to run one on a generator, check that the generator and connection are rated for it and installed safely. Gas water heaters need proper venting and should be checked if flooding reached the burner area.
After the storm
- Check for a boil-water notice from your water utility before drinking tap water.
- Look for leaks: turn the main on slowly and check under sinks, around the water heater and for running-water sounds. A water meter test can reveal hidden leaks.
- Watch for sewer problems: slow drains, gurgling or sewage odors can mean a damaged or overloaded line. Stop using water and call a plumber. See sewer line services.
- Don’t use a flooded water heater until it’s inspected; flooded gas controls and electrical components can be unsafe.
- Document damage with photos before repairs for insurance.
Condo and HOA residents
High-rise buildings may shut off water to the building before or after a storm, and elevators may be out of service. Follow your association’s storm plan, and report any leaks or backups to management immediately, because they can affect other units.
Get help after the storm
After a major storm, demand for plumbers rises and response times can be longer. For active leaks or sewage, start with emergency plumbing. Call (561) 794-0131 to be connected with an independent plumber through our plumbing referral service in Boca Raton.
Frequently asked questions
Should I turn off my water before a hurricane?
If you’re evacuating or leaving the home empty, shutting off the main water valve and the water heater helps prevent damage from leaks while you’re gone.
Is tap water safe to drink after a hurricane?
Check for boil-water notices from your water utility. If one is issued, follow its instructions until it’s lifted.
Why are my drains slow after a big storm?
Heavy rain can overload sewer systems and lines, and debris or damage can cause blockages. If several drains are affected, have the main line checked.
Can I use my water heater after flooding?
If floodwater reached the heater’s controls, burner or electrical components, don’t use it until a professional has inspected it.
