NOAA’s updated 2026 Atlantic hurricane season outlook predicts 7 to 13 named storms between June 1 and November 30, with a 75 percent chance of below-normal activity. That sounds reassuring until you remember that below-normal seasons still produce direct hits, and a single storm tracking through Acadiana can do more to your plumbing than three quiet seasons combined. We’ve been responding to storm-related plumbing calls in Lafayette Parish since 2005, and one thing stands out every year: the homeowners who fared best had done a few hours of prep work before the season started.
Most of the hurricane plumbing advice you find online is written for homes with basements and sump pumps. That’s not what most of Lafayette Parish looks like. The majority of homes here sit on slab-on-grade foundations or pier-and-beam construction with crawl spaces, and the vulnerabilities that matter in this housing stock are genuinely different from what national content describes. Add Lafayette’s expansive clay soil, high humidity, and heavy seasonal rainfall, and you’re dealing with conditions that call for specific, local guidance rather than a recycled checklist from a Florida or Houston blog.
What follows is a practical guide built around how plumbing actually behaves in this region. None of it requires specialized tools or a full weekend. Most of it can be done in an afternoon before the season gets active.
Why Hurricane Prep Looks Different for Lafayette Parish Plumbing
The soil under Lafayette Parish homes is predominantly expansive clay. It swells when saturated and shrinks when it dries out, and that cycle repeats multiple times each year. Over time, this movement stresses the joints on buried pipes, shifting them slightly with each wet and dry season. A joint that’s already compromised from years of this won’t show obvious symptoms until a storm dumps several inches of rain in a few hours. That slow shift can suddenly become a failure point.
Homes built on slab foundations have pipes running through and beneath the concrete, which limits access compared to basement plumbing. Pier-and-beam homes have more accessible pipe runs, but those crawl spaces can collect standing water during heavy flooding, exposing connections to prolonged moisture. Neither situation matches the basement-centric scenarios that national hurricane prep articles describe.
Locate & Test Your Main Water Shutoff Valve
Knowing where your main shutoff valve is sounds basic, but a surprising number of households have only one person who knows, and that person isn’t always home when something goes wrong. Before hurricane season gets active, walk every adult in the household to the valve and show them how to operate it. Then actually turn it.
A shutoff valve that hasn’t been touched in years can corrode or seize in the open position. Discovering that during a storm watch, when you need to cut the water immediately, is a genuinely bad situation. Turning the valve during a calm week before the season starts tells you whether it moves freely and gives you time to have it serviced if it doesn’t.
It’s also worth asking us about a backflow prevention device on your main sewer line if you don’t already have one. A backflow preventer is a check valve that allows sewage to flow in only one direction (out of your home), blocking it from reversing back inside when municipal sewer systems become overwhelmed by storm flooding. Lafayette’s sewer lift stations can be knocked offline during power outages, which raises the risk of sewer backflow in lower-lying areas. A prevention device installed before the season is a far simpler fix than cleaning up sewage inside the home after one.
Secure Outdoor Fixtures & Clear Drainage Before the Storm
Outdoor plumbing components are the most exposed to wind and debris. Walk the exterior of your home and disconnect garden hoses from all hose bibs before a storm arrives. A hose left connected during high winds can act as a lever on the bib fitting, and those fittings connect directly to interior supply lines. Disconnecting takes about two minutes per fixture.
If you have exposed pipe runs on exterior walls, foam insulation covers designed for freeze protection also add a layer of protection against flying debris. They’re available at any hardware store and take minutes to install.
Drainage clearance matters as much as fixture protection, particularly for slab homes:
- Clean gutters and downspouts so water flows away from the foundation rather than pooling against it
- Clear yard drains and area drains of leaves and debris so surface water has somewhere to go during heavy rainfall
- Check the grade around your foundation to confirm the soil still slopes away from the home rather than toward it
- Note any large trees near underground lines. South Louisiana’s mature oak and pecan root systems can encroach on buried pipes, and high winds that topple a tree can pull those roots through a line
Tree root intrusion is usually a slow process, but hurricane-force winds loading a root system create sudden lateral force on whatever that root has wrapped around. A pre-season camera inspection of your sewer line is the only reliable way to know whether roots are already inside the pipe.
What to Do When a Storm Arrives & After It Passes
Storm response splits into two distinct phases: what you do before landfall and what you do once the storm has moved through.
Before the Storm Makes Landfall
If you’re evacuating, shut off the main water valve before you leave. This keeps contaminated floodwater from entering the supply system through any breach in the lines while the home is unoccupied. If you’re sheltering in place, fill bathtubs and available containers before the storm arrives. Lafayette Utilities System and neighboring parish water districts have issued boil water advisories tied to power outages and pressure loss during severe weather events. When LUS loses power and pressure drops in the distribution system, pathogens can enter the water supply, and a boil advisory can stay in effect for days while the system is flushed and tested. Stored water means you’re not dependent on the tap for drinking and cooking during that window.
After the Storm Passes
Water service restoration takes longer than most people expect. According to LUS, crews can’t deploy throughout the city until sustained winds drop below 39 mph, which means pressure and service can take considerably longer to return than residents anticipate after a fast-moving storm. Plan for that gap rather than assuming service will be back within hours.
When you restore water to the home after an absence, turn on an exterior faucet first and let it run for a minute before using interior fixtures. If the water runs discolored or has an unusual odor, don’t use it until your utility provider confirms service has been cleared.
Warning Signs Worth Addressing Before the Season Starts
Some problems are worth catching now rather than waiting to see how they develop. Slow drains, gurgling sounds when you flush or run water, damp spots on walls or ceilings, and any visible pipe corrosion are all worth an inspection before June. A slow drain that’s manageable in spring can become a backed-up sewer line during a July storm when the system is under flood pressure. A pre-season inspection covers what matters most: shutoff valve condition, visible pipe condition, drainage performance, and any signs of root intrusion or joint stress in buried lines. Catching a developing problem now costs considerably less than an emergency call at midnight after a storm has pushed it to failure.
Storm damage doesn’t follow business hours. A 5 Star Plumbing Co. is available 24/7 for emergency plumbing calls throughout Lafayette Parish, and we offer same-day service when scheduling permits. If unexpected repairs create a financial concern, we also offer financing options to help spread out the cost.
A few hours of prep before the season gets active can prevent days of disruption afterward. To schedule a pre-season inspection or ask about your home’s specific setup, reach out to us at (337) 202-0246.
