How to Add Battery Backup to Your Existing Sump Pump in Canada

How to Add Battery Backup to Your Existing Sump Pump in Canada
A power outage during heavy rain can leave a basement vulnerable: your sump pump may be in working order, but without electricity it cannot move water out of the sump pit. For Canadian homeowners with an existing submersible sump pump, an inverter-based battery backup can be an alternative to installing a second pump.



Can you add backup power to the pump you already own?

Often, yes - provided the pump is electrically compatible. Pump Sentry supplies AC power to a connected pump from an external battery when utility power is interrupted. It is a power-backup system, not a replacement pump, so the existing sump pump must be in good operating condition.

What to check before buying

Pump type: Confirm that you have a compatible submersible AC sump pump, rather than a pedestal pump. Electrical requirements: Find the pump model, running amperage and starting current requirements.

Battery: A suitable external deep-cycle battery is required and is sold separately.
Installation: Confirm there is a safe location for the unit and battery enclosure near the pump and outlet.

How the system operates

During normal service, utility power operates the pump and the system maintains battery charging. During an outage, the system switches to battery-supplied AC power so the existing pump can continue cycling. When utility power returns, normal operation and charging resume. Installation and testing must follow the current manufacturer's manual; consult a qualified installer or electrician where appropriate.

Is the 822PS the right choice?

The Pump Sentry 822PS is designed for compatible sump pumps with a normal operating current of up to 9 amps. Higher-demand pumps and sewage ejector applications may require the 1733 instead. Horsepower alone does not establish compatibility, so check the pump nameplate before selecting a model.

Frequently asked questions

Do I need to replace my sump pump?
 Not if your existing pump is functioning properly and meets the backup system requirements.

Does Pump Sentry include a battery?
No, the external battery is sold separately.

Will it protect against a broken pump?
No. It provides backup electrical power, not a second pumping mechanism.
