Hurricane Season and Your Water System: What to Do Before and After a Storm
Oct 01, 2026The short version: before a storm, put the lid on tight on an outdoor brine tank and unplug outdoor equipment if you expect surges. After the storm, check the time on your softener’s display, follow any boil-water notice to the letter, and don’t drink from a well that was under floodwater until it has been disinfected and a bacteria test comes back clear. A softener, filter or drinking water system does not replace a boil-water notice.
Before the storm
- Check the brine tank lid. Most softeners around Bradenton and Parrish sit outside. A cracked or loose lid lets rain in, and a brine tank full of rainwater is one of the most common service calls we get after a wet week.
- Top up the salt. If power or roads are out for a few days, you won’t want to haul bags. Keep the tank at least a quarter full.
- Unplug outdoor equipment if you expect surges. Softener valves, UV systems and chlorine injection pumps all have electronics. Unplugging them during the worst of the storm protects the circuit boards. Plug them back in once power is steady.
- Fill some containers. Standard hurricane advice applies to everyone, city or well: store drinking water before the storm, because a well pump won’t run without power.
After a power outage
When the power comes back, look at the display on your softener. Many valves lose the time of day in a long outage, and a softener that thinks it’s 2 in the afternoon will regenerate while you’re showering. Reset the clock, or call us and we’ll walk you through it.
A UV system does nothing while it’s off. If your well has UV and the power was out, the water that sat in the lines during the outage wasn’t treated. Run the taps for a few minutes after the lamp comes back on. If the UV lamp shows a fault after the outage, call before drinking the water.
Reverse osmosis systems like the Micromax 7000 run on household water pressure and use no electricity, so an outage alone doesn’t affect them.
If your well was under floodwater
Floodwater can carry bacteria from septic systems, livestock and runoff into a well. If water covered the top of your well casing, treat the water as contaminated until it’s tested. The Florida Department of Health’s county offices publish the same basic steps:
- Use bottled water, or bring tap water to a rolling boil for one minute, until the well is cleared.
- Disinfect the well with unscented household bleach and let it sit in the plumbing for at least 8 hours, then flush until the bleach smell is gone.
- Take a bacteria sample on two days in a row, after the chlorine is flushed out.
The full instructions, with amounts, are on the Florida Department of Health in Hillsborough County page. Your own county health department can tell you where to drop off a sample. If you have a water treatment system on the well, call us before you shock it. Bleach can damage softener resin and some filter media, so we usually bypass the equipment first.
If a boil-water notice goes out
Utilities issue boil-water notices after main breaks and pressure drops, and they’re common after big storms. Follow the notice exactly. Your softener, whole-home filter or drinking water system is not a substitute for boiling. Once the notice is lifted:
- Run each faucet for a few minutes to clear the lines.
- Change the refrigerator filter and dump the first few batches of ice.
- For an RO system, it’s a good time to change the pre-filters and sanitize the system. If you’re not sure how, we can do it on a service visit.
We post local boil-water notices on our water alerts page as we see them.
If floodwater reached the equipment
If water got into the softener’s control valve, the brine tank or a UV controller, leave it unplugged and call. A valve that sat underwater usually needs to be cleaned or replaced, and a flooded brine tank needs to be emptied, sanitized and refilled with fresh salt. The resin tank itself is sealed and usually comes through fine.
Common questions
Should I turn off my water softener before a hurricane?
You don’t have to, but unplugging the control valve during the storm protects its electronics from surges. Plug it back in once the power is steady and check that the time on the display is right.
Is my well water OK to drink after a flood?
If floodwater covered the top of the well, don’t drink it until the well has been disinfected and a bacteria test comes back clear. Use bottled water or boiled water in the meantime, as the Florida Department of Health advises.
Does a water softener or filter protect me during a boil-water notice?
No. Softeners and whole-home filters are not designed to disinfect water. Follow the boil-water notice until the utility lifts it.
My brine tank filled with rain. What do I do?
Scoop or siphon out the water, check the lid, and add fresh salt. If the water level stays high or you get hard water afterward, the softener may need a service visit.
