Storm season exposes whatever was already marginal. The systems that fail in a hurricane are usually the ones that were coping rather than working, and the failures are predictable enough to prevent.
This page is about the things worth doing before the season rather than during it, when every plumber in the city has the same calendar.
What actually fails, and why
- Septic systems back up because saturated ground removes the unsaturated soil a drain field needs to work. A system that's marginal in spring becomes a problem in a wet August.
- Pumps stop because the power goes. Grinder pumps, lift stations and sump pumps are all electrical, and the household keeps producing water regardless.
- Sump pits overwhelm where the pump was sized for ordinary rain rather than a storm.
- Sewer laterals surcharge when the municipal system is at capacity, pushing water back toward properties.
- Gas appliances stop because many need electricity for ignition and controls, so having gas doesn't mean having hot water.
- Shut-off valves seize precisely when somebody needs to turn one in a hurry.
The pre-season checklist
- Test every pump. Pour a bucket into the sump pit. Confirm grinder pumps and lift station alarms work. This is the highest value item on the list.
- Check backup power for anything critical, and replace backup batteries on schedule rather than when they fail.
- Get septic pumped if it's near due. Going into wet season with a tank that's nearly full is choosing the problem.
- Find and test your shut-off valves, main water and gas. A seized valve discovered during an emergency is a much worse discovery.
- Clear drains and gutters so water goes where it's meant to.
- Check the sump discharge is clear and directs water away from the building.
- Know what works without power, particularly which gas appliances will and won't run.
On septic specifically
Florida leans heavily on onsite systems, with roughly 2.5 million households on septic according to state environmental data. In Hillsborough County the water table is the governing constraint, and it rises with the season.
If your system has backed up during past storms and recovered when the ground dried, that's not a system that's fine. It's a system that's surviving, and each wet season it has less margin. Pre-season is the right time to look at it, both because there's time to act on what we find and because the ground is dry enough to assess properly.
During and after a storm
Practical points worth knowing in advance:
- Minimise water use during an outage if you're on a pump system. Without power there's no drainage, and the tank or pit fills anyway.
- An alarm during an outage is usually correct, not a fault. It's reporting a real level.
- Don't assume it's fine when power returns. If an alarm doesn't clear once the pump has had time to catch up, that's the point to call.
- Be careful with flood water around a septic system or a backed up fixture. Treat it as contaminated.
- If the ground over your drain field is saturated, reducing water use for a few days is often the difference between coping and backing up.
Why book early
The honest commercial reason is capacity. In the days around a forecast storm, every plumber in Tampa is dealing with emergencies, and routine preventive work moves to the back of the queue behind people whose houses are actively flooding. That's the right priority order, and it's why the check is worth doing in May.
