Compare a backup sump pump’s flow curve with site head and water inflow, then check battery and controller limits for the exact system.
Severe weather safety guides
Use official alerts, local instructions, shelter or evacuation decisions, and household fallbacks to prepare for dangerous weather.
Protect your foundation from flooding. Map your roof runoff, surface grading, and basement seepage to identify when you need a drainage professional.
Compare backwater valves and overhead sewer systems as site-specific ways to reduce basement sewer-backup risk, with a licensed plumber and local-code review.
Review window well drainage, cover operation, and emergency escape space with a qualified local contractor before making changes.
Relative humidity changes with air temperature. Compare it with dew point to understand how two outdoor forecasts can have different moisture content, then keep indoor readings separate.
Sleet reaches the ground as ice pellets; freezing rain reaches it as liquid and freezes on contact. Use the forecast timing, impacts, and local instructions to decide what to postpone and what to check at home.
