What drives the price

- Pump type and capacity
- Backup system (battery or water-powered)
- Discharge line routing and freeze protection
- Electrical or plumbing work, which may need a separately licensed trade in Westchester
Frequently asked questions
Is replacing a pump cheaper than a new install?
Usually, when the pit, discharge and outlet are already in place.
Should I add a backup?
If your basement floods when the pump stops, a backup is worth pricing, especially since storms often cause power outages.
