Sump Pump Services in Toronto & the GTA
Toronto & the GTA • Call 647-784-8448
Sump pump work is a system, not a product. The pump matters; so does the basin, the check valve, the discharge route, the alarm, the battery backup, and the electrical setup. Tornado Plumbing & Drains handles installation, replacement, repair, and maintenance for sump systems across Toronto and the GTA — including battery backup integration and Toronto subsidy paperwork.

How a professional visit usually unfolds
Assess the system
Inspect the basin, pump age, float action, check valve, discharge path, and the circuit it runs on Pinpoints whether you need a repair, a single component, or a full replacement before any parts are ordered
Size and select
Match pump capacity to your water inflow, pit depth, and discharge head, and confirm basin and lid fit An undersized pump short-cycles and dies early; an oversized one wastes the basin and runs rough
Install and route
Set the pump and float, fit a check valve, seal the lid, and route discharge away from the foundation Stops backflow, recirculation, and the basin odour and noise that come from a poorly built setup
Protect for outages and winter
Add battery backup or an alarm if requested and guard the exterior line against freezing Power cuts and frozen discharge lines are the two most common ways a healthy pump still floods a basement
Test and document
Run full pump cycles, hand over the subsidy paperwork, and register the 25-year workmanship warranty Confirms the system triggers and clears water under load and keeps your Toronto subsidy claim on track

25-year workmanship warranty
Every job Tornado Plumbing & Drains completes in Toronto and the GTA — repair, install, replacement, drain work, sewer work, fixture work — is backed by a 25-year workmanship warranty. The written terms are provided with every quote. If our work fails within 25 years of the install date, we come back and make it right.
Why the basin and discharge matter as much as the pump
Most sump failures aren't the motor giving out — they're the float wedging against the basin wall, a check valve that lets discharged water fall back in, or a frozen exterior discharge line that dead-heads the pump. We size the pump to the actual water volume reaching your basin, set the float so it isn't fighting the inlet pipe, and route discharge far enough from the foundation that it doesn't recirculate. When a system can't keep up during spring melt or a summer downpour, the fix is usually upstream of the pump itself, which is why we look at sump pump repair and maintenance before assuming a full replacement.
When homeowners call us about a sump system
- Pump runs constantly or short-cycles every minute — usually a stuck float, an undersized pump, or groundwater pouring in faster than the basin can handle
- Pit fills and the pump never kicks on, or the basement floods during a storm despite a working pump on dry days
- Loud hammering, gurgling, or a clunk after each cycle — typically a failed or missing check valve letting water surge back down the discharge pipe
- Discharge line freezes shut in winter and the pump burns out trying to push against a blocked exterior pipe
- Pump is well past 7-10 years, motor smells hot, or it cycled non-stop through a power outage with no battery backup
- Basin is too small or cracked, the lid doesn't seal, or radon and sewer odour rise from an open pit
- Discharge runs rusty or silty and the pump strains — sediment has clogged the intake screen or seized the impeller in the pit
What's included
- On-site assessment of the basin, pump, float, check valve, discharge route, and the dedicated electrical circuit feeding the system
- Pump sizing and selection matched to your water volume, sump depth, and discharge head — not a one-size box off the truck
- Supply and install of the pump, a quiet check valve, and a sealed basin lid, with the float positioned clear of the walls and inlet
- Discharge piping corrected so water exits well away from the foundation, with freeze-resistant routing where the line runs outdoors
- Battery backup or high-water alarm integration when requested, plus testing the float and switch through full cycles before we leave
- Toronto basement flooding subsidy paperwork prepared and a permit pulled where the scope requires it
- Haul-away of the old pump, cleanup of the work area, and a written 25-year workmanship warranty on the installation

Toronto subsidy planning
Sump pump and battery backup work qualifies under the City of Toronto's Basement Flooding Protection Subsidy Program. The expanded program starts May 1, 2026, with up to $6,650 per property for eligible work completed on or after November 12, 2025. Subsidy rules depend on property eligibility, work type, and contractor licensing. Confirm with the City before assuming a net cost.
Sump pump pricing
Pricing depends on whether the work is a pump-only replacement, a full new install with basin, or a battery backup upgrade. Pump-only replacement is the lowest range. New basin installation in a concrete floor is the highest. Battery backup is an add-on that can be installed at the same time as primary pump work.
What to share when you call
- Whether a pump and pit already exist.
- Symptoms (slow pumping, repeated cycling, alarm trips, water in basement).
- Whether the basement is finished.
- Storm and outage history.
- Whether you plan to apply for City subsidy.
- Photos of the pit, pump, and discharge.
Toronto context
Sump pumps in Toronto basements typically run hardest in spring melt and during the same June-to-September storm window the combined sewer surcharges. The right install isn't just one pump — it's primary, secondary or battery backup, alarmed float, and a discharge that doesn't loop back to the foundation.
What to confirm before approving sump work
- The quote should separate pump, basin, check valve, discharge, and backup.
- The discharge outlet should be tested, not assumed.
- Subsidy eligibility should be confirmed before assuming a net cost.
Useful info on the call: existing system, symptoms, and subsidy plans.
Frequently asked questions
Is a sump pump enough to prevent basement flooding?
It handles groundwater. It does not stop sewer surcharge (a backwater valve does that) and it does not seal the foundation (waterproofing does that). Many Toronto homes need a combination.
How long does a sump pump last?
Typically 7 to 10 years for a primary submersible pump. Heavy use, hard water, and sediment shorten life. Annual testing helps catch decline before failure.
Should I add a battery backup?
Yes if storms in your area cause both water entry and power outages. Without backup, a storm-and-outage combination puts the basement at risk.
How does the Toronto subsidy work?
The City has an expanded program starting May 1, 2026, covering up to $6,650 per property for eligible work completed on or after November 12, 2025. Eligible work includes sump pump and battery backup. We provide the documentation the City requires.
