How to Choose a Sump Pump
HP Rating
1/3 HP handles most homes. Choose 1/2 HP for heavy water flow or high water tables.
Submersible vs Pedestal
Submersible (in the pit) are quieter and more common. Pedestal pumps are cheaper but louder.
Battery Backup
Essential if you live in flood-prone areas. Power outages during storms are when you need it most.
Flow Rate (GPH)
Higher GPH = handles more water. Most basements need 2,500+ GPH at 10-foot head.
Float Switch
Vertical switches are more reliable than tethered switches in tight pits.
