- Pump type: pedestal or submersible.
- Replacing an existing pump versus a new pit.
- Battery backup or water-powered backup.
- Drainage, discharge line, and pit work.
- Regional labor rates.
Key cost factors
Replace vs new install
Swapping an existing pump is quick and cheap. A new install requires breaking concrete and digging a pit, which is the bigger cost.
Backup matters
A battery or water-powered backup keeps the pump running during the power outages that often accompany heavy storms, when you need it most.
