When this service makes sense
Part of Basement Waterproofing & Flood Prevention in Toronto & the GTA
Book this service when
Book this when the existing pump has failed, is past 8 to 10 years old, hums or trips the breaker without spinning up, or repair parts cost nearly as much as a new unit.
Common signs
- Replacement parts — impeller, motor, or seal kit — cost nearly as much as a new pump on a unit that has already aged out
- A pedestal pump you want upgraded to a quieter, higher-capacity submersible
- The motor hums or trips the breaker but won't spin up — a seized motor that isn't worth rebuilding
- Rust, an oil sheen on the pit water, or a burnt smell, all pointing to failed internal seals
If you're not sure, compare these too
- Sump Pump Repair & Maintenance - when the pump is under 8 years old and the fault may be a float or check valve
- Sump Pump Installation - when the pump short-cycles because the pit is too small
- Battery Backup Sump Pump - the most cost-effective time to add backup is during a swap

Quick guide and key details
What changes price and scope
- Whether the pit and discharge are in good shape.
- Whether the basin is undersized or the discharge needs upgrading.
- Whether a battery backup is added at the same time.
How a professional visit usually unfolds
1. Inspect the pit and pump
Confirm the existing setup is reusable. If basin or discharge has issues, those should be addressed too.
2. Choose the new pump
Match horsepower and float style to the home and pit. Right pump for the actual workload.
3. Swap the pump
Remove old pump, install new one with new check valve if needed. Permanent replacement.
4. Test
Fill the pit, confirm pump activates and discharges correctly. Confirms the system works.
5. Discuss backup
Explain battery backup options if the home is at storm-and-outage risk. Most cost-effective time to add backup.

When a swap beats another repair
Once a sump pump has worn its bearings or burned out the motor, repair rarely pays off — the parts approach the cost of a new pump and the rest of the unit is the same age. We match the replacement to your pit and incoming water volume, so an undersized 1/4 HP that never kept up gets moved to a 1/3 or 1/2 HP unit, and a cracked or sediment-packed basin gets flagged for a basin replacement before the new pump goes in. For homes that lose power during the same storms that flood them, we'll talk through adding a battery backup while the pit is open.
When replacement is the right call, not repair
- Replacement parts — impeller, motor, or seal kit — cost nearly as much as a new pump on a unit that has already aged out
- A pedestal pump you want upgraded to a quieter, higher-capacity submersible
- The motor hums or trips the breaker but won't spin up — a seized motor that isn't worth rebuilding
- Rust, an oil sheen on the pit water, or a burnt smell, all pointing to failed internal seals
- A pump that kept up when it was installed but can no longer handle the storms — undersized for current inflow
- You're finishing the basement or selling and want a current, warrantied pump in place
- You'd rather schedule the swap now than have it quit during the next overnight storm
What's included
- Sizing to your pit depth, basin diameter, and how fast the pit refills — not just matching the old horsepower rating
- Pulling and hauling away the old pump, then clearing sediment and gravel from the bottom of the basin
- Setting the new submersible on a stable, level base so the float swings freely and the intake stays up off the silt
- A new check valve (quiet spring-style available) so discharged water can't drain back and double-cycle the pump
- Replacing cracked or undersized discharge fittings and confirming the line carries water away from the foundation
- A full fill-and-pump cycle to set the float on/off points, plus a high-water alarm fitted if you want one
- Optional battery backup or a second pump quoted on site, and a written 25-year workmanship warranty on the install
Replace the pump if you notice:
- Pump runs but the basin keeps rising.
- Pump cycles constantly even between storms.
- Loud, grinding, or rattling pump motor.
- Pump older than 8 to 10 years.
- Pump that has already failed once during a storm.
- Float stuck or no longer activates the pump.
Replacement cost
Pump-only replacement stays straightforward when the pit and discharge are in good shape. Pricing climbs only when the basin is undersized, the discharge needs upgrading, or a battery backup is added at the same time.
What to share when you call
- Approximate age of the existing pump.
- Brand and horsepower if you know them.
- Whether the pit is a standard size.
- Whether you have storm or outage concerns.
- Photos of the pit, pump, and discharge.
- Whether you plan to apply for subsidy on a battery backup add-on.
Toronto context
Most Toronto sump pumps that fail are 8-12 years old, with float switches that have stuck open or impellers that have lost flow. Replacement is the fast path; we size the new pump to the actual basin and lift, add an alarm if the existing setup didn't have one, and confirm the discharge still drains away from the foundation.
What to confirm before approving replacement
- The new pump should be sized to the actual workload, not just whatever is on the truck.
- Check valve and discharge should be inspected, not assumed.
- Battery backup should be discussed at the same time — it is the cheapest moment to add it.
Useful info on the call: pump age, brand, pit size, and storm history.
Frequently asked questions
How long does replacement take?
Most pump-only swaps take an hour to two. Replacements that include check valve, discharge upgrade, or battery backup take longer.
Do you replace any brand?
Yes. We carry standard residential brands and can match horsepower to the existing pit and discharge.
Should I upgrade horsepower?
Sometimes. If the existing pump cycled constantly during storms, a slightly larger pump can help. Going too large is also a problem — pumps short-cycle if they outpace the inflow.
Does pump replacement qualify for subsidy?
Sump pump and battery backup work qualifies under the City of Toronto 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.

Kylie Walters - Toronto Realtor
May 2026“Highly recommend Serhiy and Tornado Plumbing! They were incredibly quick to respond, professional, friendly, and honest throughout the whole process. What I thought could turn into a huge and expensive project ended up having a much simpler solution because Serhiy took the time to assess everything properly and give genuine advice instead of pushing unnecessary work. He found a great solution for installing my backwater valve and made the entire process easy and stress-free. It's hard to find people who are both skilled and honest these days, and I wouldn't hesitate to use them again.”

July 2020“OUTSTANDING SERVICE! I highly recommend Tornado Plumbing and Drains. I had a backwater valve installed as well as a new toilet. My work was completed in a timely fashion at a VERY reasonable price. Serhiy, Michael and their team were extremely neat, courteous, and efficient. They were very helpful and went over and above what was required of them...at no extra charge. In a world of mediocrity, Excellence is rare. EXCELLENCE means doing everything you are supposed to, and a little bit more. TORNADO PLUMBING AND DRAINS IS THE DEFINITION OF EXCELLENCE! I highly recommend them, in fact I already have. Thanks for a job VERY well done!!”

June 2024“I was very happy with Tornado Plumbing's services. Every step of the procedure was executed professionally, very neatly, and exceptionally promptly. They were also very flexible with regards to accommodating our availability. Although, as with most customers presumably, I am not particularly well educated on the finer points of water supplies, drains, backwater valves, and the like, Tornado Plumbing's work appears to be have been performed very skillfully. I am not able to provide any valuable insight about how Tornado's prices compare with other companies' prices, since I simply relied on the recommendation of friends when I contracted with Tornado. I can say, however, that there was no "hard selling" and no "hidden costs" in our project; the final price was exactly as quoted initially by Serhiy. In addition to the above, I shall add that Serhiy was very friendly, and also willing to answer (very patiently) any questions that arose during our project. Conclusion: I am happy to recommend Tornado Plumbing.”
