A sump pump is the cheapest flood insurance a basement can have — $500–$1,500 installed versus tens of thousands in water damage. Yet most pumps are ignored until the one storm that matters. This section covers installation costs, pedestal vs submersible types, battery backup systems (the difference between a dry basement and a disaster during a power outage), and the 5-minute maintenance that keeps pumps alive.
Battery backup is not optional
Storms that flood basements also knock out power. A battery backup or water-powered backup pump is what stands between you and a flooded basement at 2 AM. Our guides compare the options honestly, including runtime realities.
Test it before the rain
Pour a bucket of water in the pit twice a year. If the pump doesn't kick on, cycle fully and shut off, you just bought yourself time to fix it — instead of discovering the failure mid-storm.
