Hurricane Plumbing Prep for Maryland Homeowners: Before and After the Storm

July 5, 2026 · 5 min read · By Deep Dive Plumbing Maryland

Maryland's Chesapeake Bay location makes it vulnerable to hurricanes, tropical storms, and nor'easters. For homeowners with well water systems, storm preparedness includes protecting your water supply. Here is a complete checklist.

Before the Storm

Test your sump pump — pour water in the pit to confirm it activates
Check sump pump discharge line is clear and directed away from the foundation
Confirm battery backup sump pump is charged and functional
Locate your main water shutoff and make sure it operates freely
Clear gutters and downspouts to direct water away from the foundation
Check well pump house is secure and weathertight
Store a 3-day supply of bottled water (1 gallon per person per day)
Know your sewer cleanout location in case of backup

After the Storm

Do not use well water until tested if flooding reached the wellhead
Check for signs of sewer backup before using drains
Inspect exposed pipes for damage
Check water heater for flood damage before restoring power
Document any damage with photos for insurance

Frequently Asked Questions

What should I do with my well water after a hurricane?

If floodwater reached your wellhead, do not use the well water until it has been shock chlorinated and tested for bacteria. Floodwater carries bacteria, sewage, and chemicals that can contaminate your well. Use bottled water for drinking, cooking, and brushing teeth until the well has been treated and tested negative for bacteria.

How do I protect my sump pump during a hurricane?

The most important protection is a battery backup sump pump. When a hurricane causes power outages, your primary sump pump stops working — exactly when you need it most. A battery backup activates automatically when the primary pump fails or loses power. Test your backup before hurricane season and replace the battery every 3–5 years.

What if my sewer backs up during a storm?

Sewer backups during heavy rain are caused by the municipal sewer system becoming overwhelmed (surcharging) and pushing sewage back into homes through the lowest drain. Stop using water in the house immediately. A backwater valve (check valve) on the main sewer line prevents this — consider installing one if you have experienced storm-related backups.

"Absolutely blown away by the service from Deep Dive Plumbing Maryland! We had ongoing issues with our well water for years — bad smell, staining, and constant problems with pressure — and nobody ever took the time to truly figure out the root cause. Terry and the team came out, performed a full water analysis, explained everything in detail, and designed a system specifically for our home instead of just trying to sell us random equipment. You can really tell they care about doing things the right way. The install was extremely clean and professional, they walked us through how everything works, and our water has never looked or tasted better. The difference is unbelievable."

"We had our water heater leak and flood our basement. Deep Dive Plumbing Maryland came out Saturday morning and got us a new heater same day for a very reasonable price, and also replaced the shutoff valve that was old and wouldn't stop dripping."
