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.
Sizing the pump to your groundwater, not a box-store guess
Most basement floods we see in the GTA trace back to a pump that was undersized for the actual inflow, a pit that holds too little water so the motor short-cycles, or a discharge line that dumps too close to the foundation and recirculates. We measure your pit dimensions, watch how fast water enters during the visit, and match horsepower, switch type, and check valve to that reality. We also confirm the discharge runs far enough out and pitches away from the wall so the same water is not pulled back in. If your storm risk is high, we plan the pit and lid around a future battery backup sump pump so power outages during a storm do not become a flooded basement.
A proper sump pump installation should confirm:
- Whether the home already has a sump pit or needs a new basin.
- Whether the existing pump is undersized, failing, or poorly installed.
- Whether the check valve is noisy, stuck, missing, or allowing water to return.
- Whether the discharge line sends water far enough away from the foundation.
- Whether the pump needs an alarm or battery backup.
- Whether the electrical setup is safe and practical.
- Whether the basement is finished or high-risk during storms.
- Whether City of Toronto subsidy paperwork may apply.
Sump pump options compared
| Option | Best for | Main limitation |
|---|---|---|
| Primary submersible sump pump | Most finished basements and regular groundwater control | Depends on power unless backup is added. |
| Pump replacement only | Existing pit and discharge are usable | Does not fix a bad basin, discharge, or backup-power issue. |
| New pit + pump | Homes without a proper sump basin | More labour, floor opening, and drainage planning. |
| Battery backup sump pump | Storms where power loss and water entry happen together | Battery condition must be maintained. |
| High-water alarm | Early warning before overflow | Warns only; does not pump water. |
| Discharge upgrade | Water returns near the foundation or freezes outside | Requires correct routing and site planning. |
Common reasons people call for sump pump installation
- A basement with groundwater seepage or known storm-season water pressure.
- A failed, undersized, or aging sump pump that is no longer reliable.
- A property preparing for flood prevention before the next major rain event.
- A finished basement where pump failure would be especially expensive.
- A system that needs battery backup, basin work, or discharge improvements as part of the install.
- A homeowner comparing install, replacement, and full sump-system upgrades.
What's included
- On-site assessment of the existing pit, float clearance, inflow rate, and current discharge route, plus the right pump horsepower and switch type for your basement
- Supply and installation of the new sump pump, sealed pit lid, and a check valve sized so water cannot drain back into the pit and trigger short-cycling
- Connecting and testing the discharge line so it carries water well away from the foundation and drains in the correct direction, with freeze-resistant routing where the line runs near grade
- Wiring to a dedicated, properly grounded outlet and verifying the float and high-water alarm trip at the right levels through a full fill-and-pump test
- Pit cleanout, removal and disposal of the old pump, and full cleanup of the work area before we leave
- Permit handling and code-compliant discharge connection where required, including the documentation needed for a City of Toronto basement flooding subsidy application
- A written 25-year workmanship warranty on the installation
Sump pump installation cost in Toronto: what affects the quote
The final number is usually driven by storm exposure, groundwater pressure, discharge routing, and how the basement actually takes on water. Older housing, finished basements, buried discharge routes, power-outage risk, and permit-sensitive work can all move the job out of the simple range quickly. The quote should clearly separate the pump, basin work, check valve, discharge routing, battery backup, electrical, and testing.
What moves the price on a sump pump install
- Whether the basement already has a sump pit or a new basin is needed.
- Pump size, float style, and check-valve quality.
- Discharge route length, outlet location, and freeze-protection needs.
- Whether a battery backup, water-powered backup, or alarm is added.
- Electrical access and whether a dedicated circuit is needed.
- Permit, inspection, or shared-access requirements at the property.
Toronto sump pump rebate and subsidy planning
For City of Toronto properties, sump pump work can qualify under the City's Basement Flooding Protection Subsidy Program. As of June 2026, the City lists up to $6,650 in subsidies per property, covering up to 80% of the invoiced cost per eligible item; the expanded program starts May 1, 2026 and applies to eligible work completed on or after November 12, 2025. A sump pump with alarm and a sump pump battery backup are both eligible items, alongside backwater valves and alarms, a home plumbing assessment, and severance and capping of storm sewer or external weeping-tile connections. The work must be done by a properly licensed contractor — Tornado Plumbing & Drains holds the required licences and documents the install (invoice, permit reference, and photos) for your application. Adding a battery backup counts toward the same property cap, so plan both together. Subsidy amounts and rules depend on the property, the work date, device type, permits, and how much of the cap has already been used, so confirm current per-item amounts and eligibility on the City of Toronto Basement Flooding Protection Subsidy Program page before assuming a net cost.
When a sump pump install should be paired with other work
A sump pump manages groundwater. It does not stop sewer water from reversing through the drain system, and it does not waterproof a foundation wall by itself. If the basement has sewer backups, floor-drain backups, wall seepage, or water entering through cracks, the right plan may include a backwater valve, foundation waterproofing, weeping-tile work, drain inspection, or a battery backup system.
What helps after the install is done
Test the system before storm season, keep the pit clear, watch the discharge path, and decide early whether the house also needs battery backup or additional flood-prevention layers. For older Toronto homes, a yearly check of the float, check valve, alarm, and discharge outlet is worth more than waiting for the first failed storm.
What to prepare before the visit
- Photos of the pit, pump, discharge pipe, damp area, and floor drain.
- Notes on whether the basement is finished and what it stores.
- Whether the pump has failed during rain or power outage.
- Whether any prior flood-prevention equipment (alarms, backups, backwater valves) is installed.
- Whether you plan to apply for a City of Toronto subsidy.
- Any visible cracks, seepage points, or foundation-wall water entry.
Sump pump installation in Toronto & the GTA: local context
Older Toronto homes may have drainage layouts that worked for years but are less reliable during heavier storms, clogged weeping tile, or changing groundwater conditions. A sump pump makes sense when groundwater needs a controlled path away from the basement — and pairing it with a backwater valve, battery backup, or weeping-tile work often makes the difference during surcharged-sewer events.
What to confirm before you approve sump pump installation
- The recommendation should follow the real water-entry pattern instead of forcing every basement issue into the same flood-prevention sale.
- The quote should list pump, basin, check valve, discharge, and backup separately so you know what you are paying for.
- Subsidy eligibility should be confirmed against current City rules, not a number quoted from an old page.
The clearest booking notes usually include photos of the water-entry area, pump pit or valve location, recent storm timing, and any rebate or permit paperwork already started.
Frequently asked questions
Do I need a sump pump if my basement has never flooded?
Maybe. Older Toronto homes may have drainage layouts that worked for years but are less reliable during heavier storms, clogged weeping tile, or changing groundwater conditions. A sump pump makes sense when groundwater needs a controlled path away from the basement.
What is the difference between a sump pump and a backwater valve?
A sump pump removes groundwater collected in a pit. A backwater valve helps stop sewage from reversing into the home during sewer surcharge. Many flood-prevention plans consider both, but they solve different problems.
Should I add a battery backup?
A battery backup is worth considering when the basement is finished, the pump runs often, or storms in your area can cause both water entry and power outages. The backup gives the system a second way to pump if the primary pump fails or loses power.
What should I prepare before booking?
Send photos of the pit, pump, discharge pipe, damp area, floor drain, and any previous flood-prevention equipment. Mention whether the basement is finished, whether the pump failed during rain, and whether you are planning to apply for a City of Toronto subsidy.
How much does sump pump installation cost in Toronto?
A new sump pump installation with a fresh pit and pump starts at $720, and replacing an existing pump in a working pit is typically less. We diagnose the pit, discharge route, and power needs on site, then quote the exact price in writing before any work begins — no surprises after we start.
Do you install sewage ejector pumps as well as sump pumps?
Yes. A sump pump moves groundwater out of a pit, while a sewage ejector pump handles wastewater from a basement bathroom or laundry below the main sewer line — different pumps for different jobs. If you describe what the pump needs to drain when you book, we bring the right unit and size it correctly for your setup.
When should I replace my sump pump instead of repairing it?
If the pump is over about seven to ten years old, runs constantly, cycles on and off rapidly, or fails to clear the pit, replacement is usually the safer call than a repair. We test the float, check valve, and discharge line first, then recommend replacement only when the existing pump can no longer protect the basement reliably.
