It depends on the elevation of the specific low point the pump is protecting, whether that’s a below-grade area, an equipment pad, or a section of yard that drains poorly toward the house. In South Florida generally, and in a city like Weston with an extensive lake and canal network keeping the water table high, heavy rain events can raise groundwater faster than a lightly used floor drain or french drain can move it on its own, which is exactly the gap a sump pump fills.
The honest answer is that not every home needs one, and we’ll say so during an assessment rather than recommend a pump by default. Where one is warranted, the pump matters less than whether it’s actually tested and whether it has power during the kind of storm that knocks power out.
