Sump Pump Repair & Maintenance in Toronto & the GTA
Toronto & the GTA • Call 647-784-8448
Sump pumps fail at the worst time — during the storm they are supposed to handle. Annual maintenance catches the problems that show up later as a flooded basement: stuck float, failed check valve, frozen discharge, weak motor, dead backup battery. Tornado Plumbing & Drains tests, services, and repairs sump systems across Toronto and the GTA before storm season.

When this page makes sense
A good place to start for storm-driven water entry, repeated pump failures, or homes planning flood-prevention upgrades before the next heavy rain.
Most common signs
- Pump runs but moves no water (clogged impeller, failed check valve).
- Pump cycles constantly (oversized, short-cycling, or float issue).
- Pump runs nonstop (float stuck open).
- Pump runs but basin keeps rising (undersized for inflow).
What the visit usually includes
- 1. Inspect pit and pump: Remove debris, inspect the pump and float.
- 2. Test the float: Manually raise the float, confirm pump activates.
- 3. Test check valve: Pump down water and confirm none returns to pit.
What changes price and scope
- Whether the solution is isolated to a valve or pump, or extends into waterproofing and drainage work.
- Excavation, electrical coordination, permits, and inspection requirements.
- Existing flood history, basement layout, and access to the current drainage path.
How a professional visit usually unfolds
1. Inspect pit and pump
Remove debris, inspect the pump and float. Catches early failure signs.
2. Test the float
Manually raise the float, confirm pump activates. Confirms automatic operation.
3. Test check valve
Pump down water and confirm none returns to pit. Failed check valves cause short-cycling and pump wear.
4. Test discharge
Confirm water reaches the outlet and exits cleanly. Frozen or buried discharge causes overflow.
5. Test backup
Run the system on battery only. Confirms outage protection.

Common sump pump problems:
- Pump runs but moves no water (clogged impeller, failed check valve).
- Pump cycles constantly (oversized, short-cycling, or float issue).
- Pump runs nonstop (float stuck open).
- Pump runs but basin keeps rising (undersized for inflow).

Repair and maintenance cost
Annual maintenance is straightforward. Pricing climbs when parts (check valve, float, battery) need replacement, when the discharge needs work, or when the pump itself is failing and needs replacement at the same visit.
What to share when you call
- Symptoms (cycling, no water, alarm, water in basement).
- Pump age, brand, and horsepower if known.
- Whether you have a battery backup and how old.
- Whether the discharge is buried or above-ground.
- Storm history.
- Photos of the pit and discharge.
Toronto context
Sump pump maintenance in Toronto is the cheapest insurance a homeowner can buy — float test, basin clean, debris check, discharge clear, battery backup voltage. We run the full annual check in 30 minutes, document it, and flag anything that won't make it through one more spring melt.
What to confirm before approving the work
- Discharge should be tested all the way to the outlet, not assumed.
- Backup battery condition should be reported, not just battery presence.
- Replacement parts should be itemized.
Useful info on the call: symptoms, pump age, backup status, and storm history.
Frequently asked questions
How often should I service my sump pump?
Annually, before storm season. Many failures show up in spring and summer storms — service in April or May catches them in time.
How long do backup batteries last?
Most sealed lead-acid batteries last 3 to 5 years. They should be tested annually and replaced before they fail.
Why does my pump cycle constantly?
Most often a failed check valve allowing pumped water to return to the pit. Sometimes a stuck or short-throw float. Sometimes the pump is too large for the basin.
Should I replace the pump or repair it?
If the pump is under 5 years old and the issue is a single component (float, check valve), repair makes sense. Older pumps or repeat failures usually mean replacement is the better spend.
