Battery Backup Sump Pumps for Homes Across the GTA
Summer thunderstorms fill pits and drop hydro lines in the same hour. A secondary pump on a battery keeps working when the primary cannot.
- Backwater valve options for the main drain
- Water poured through to prove it works
- Pointers on municipal flood-protection programs

Who benefits from a second pump
Pits that refill within minutes in a downpour, finished rec rooms, and neighbourhood loses power during summer storms, a backup is worth a look. It also covers primary pump failure, which happens with no warning.
- Finished basement with flooring and drywall
- Pit that cycles every few minutes in rain
- Frequent outages on your street
- Long trips away from home
On the job, step by step
A 12-volt unit goes into the existing pit, perched a little above the main pump so it wakes only if the water climbs past normal. It is fitted with a separate check valve and tees into the shared discharge. A charger and sealed battery sit on a shelf above the pit. A buzzer warns you whenever it kicks in or its charge sags. Where city pressure is good, a water-powered backup that uses the venturi effect is an alternative and needs no battery, though it uses domestic water while running and requires a backflow preventer.
GTA houses and what they change
Small pits in older homes may not have room for two pumps; a combination unit or a larger pit liner solves that. Battery capacity limits run time, so a pit with heavy inflow drains a battery faster. Check whether your municipality’s flood protection subsidy has included backup pumps.
Before you pick up the phone
Find out the expected run time on a full charge at your pit’s inflow, and when the battery should be replaced. Call (365) 387-8531.

Common questions
How often should the backup battery be replaced?
Many sealed batteries last a few years. Test the system twice a year by pulling the main pump’s plug and running a hose into the pit.
