Sump Pump Battery Backup Installation in Etobicoke
A sump pump only works when it has power, and the storms most likely to fill a sump pit are the same storms most likely to knock out electricity. A battery backup system covers that gap.
A backup unit sits alongside the primary pump with its own float switch and battery, taking over automatically when power is lost or when the primary pump cannot keep up.

How a backup system is set up
A deep-cycle battery, a charger and a secondary DC pump are installed at the sump. The charger keeps the battery maintained while power is available. When the primary pump loses power or fails, the backup float triggers the secondary pump and it discharges through the same or a dedicated line.
Runtime depends on battery capacity, how much water is arriving, and how often the pump cycles. No backup runs indefinitely, so the realistic expectation for a given setup is worth discussing before installation rather than after an outage.
Problems this service addresses
- Power outages during the exact storms that fill the sump
- A single pump with no redundancy in a flood-prone basement
- Primary pump failure with no secondary protection
- High inflow that exceeds one pump's capacity
- Homes left unattended during vacations or travel
Potential benefits
Continued sump operation during certain power outages
Redundancy if the primary pump fails mechanically
Added protection for finished lower levels
Alarms on many systems warn of a problem early
How the process works
Review the existing sump
Pit size, primary pump condition, inflow rate and discharge line are assessed.
Size the backup
Battery capacity and pump selection are matched to expected inflow and desired runtime.
Install and wire
The backup pump, battery, charger and float are installed and connected to the discharge.
Test the changeover
The system is tested by simulating a power loss so you can see the backup take over.
