Interior Drains + Sump Pumps

How it works

Engineered for Florida conditions.

Interior drains capture water under the home before it pools in the crawlspace. Water flows by gravity to the sump pit; the pump then forces it out a solid discharge line to an approved location 10–20+ feet from the foundation. That last part — the powered lift to a legal discharge — is what separates a sump system from every gravity-only fix, and it’s why sumps are standard equipment on Central Florida’s flat lots.

Here’s the honest version of the question most contractors won’t answer directly: does a sump pump even make sense in Florida? It depends on two measurements, not on sales pressure. First, the wet-season water table. USDA soil mapping for the sands under coastal Volusia puts the summer water table around 40–60 inches below grade — and shallower near the coast and in flatwoods pockets. When groundwater rides that high, a gravity trench has nowhere to send water, and a sump is the only outlet that works in September, when it matters. Second, fall to a legal discharge point. If your lot genuinely drops from the problem area to a swale or approved outlet, gravity can finish the job — and a sump is an unnecessary expense we won’t sell you.

The decision table we actually use: standing water plus a high wet-season table plus no usable slope → sump system. Damp crawlspace with limited exterior access → interior drain to a sump. Real fall to a legal outlet and surface-only ponding → gravity French drain or grading, no sump. If an estimator specs a sump without measuring water table behavior and discharge fall, they’re quoting a product, not designing a system.

What a complete FloGuard sump installation includes: a sealed basin sized for inflow (not a bucket-sized pit that short-cycles the pump), a submersible pump with float switch matched to head height and run length, a check valve so discharged water can’t siphon back, a solid — not perforated — discharge line to a code-compliant outlet, and clean electrical with a dedicated circuit. Undersized basins and missing check valves are the two shortcuts that kill cheap installs within a season or two.

Hurricane season is the stress test. Storms take out grid power at exactly the moment groundwater peaks — which is why we recommend battery backup or dual-pump setups for homes that flood hard. A backup pump that runs a few hours through an outage is the difference between a dry slab and a flooded crawlspace during a September tropical system. Smart monitoring is available so you know the pump cycled overnight instead of guessing.

Where the water goes is a legal question, not just a plumbing one. Discharge must reach an approved location — a swale, storm connection, or low area on your own lot well away from the foundation. Volusia County code prohibits sending harmful runoff onto adjacent property, and cities like Port Orange require a right-of-way permit for any line that touches public ROW. We design the discharge path first, then the system that feeds it — and we handle the city conversation when a project touches public right-of-way.

Maintenance reality: a sump pump is a mechanical device that sits idle for months and then has to work flawlessly for a week straight. Pour-test it monthly (a bucket of water in the basin should kick the float and clear the pit), and have it professionally checked yearly before the May–October wet season — float, check valve, discharge line, battery health, and sediment in the basin. Florida’s fine sand finds its way into everything; a basin cleaning at the right time is vastly cheaper than a burned-out pump during a storm.

This service is ideal when yards are too flat for gravity-only discharge, when crawlspaces stay damp through the wet season, when exterior trenching access is limited — and it’s the wrong buy when your lot has real fall to a legal outlet. A free on-site assessment settles which one you have; that’s why we don’t quote sump systems over the phone.
