Two lifespans
It sits idle for months, then fails the one storm you need it, and the low area floods. Test it before the season, not during it.

The facts
Florida homes are more likely to have a slab than a basement, so sump pumps are less common. Where they exist, they usually protect a crawlspace or a low utility area, and hurricane season is what they are built for.
