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.

Book this service when
Book this before storm season, or when the pump runs but moves no water, cycles constantly, runs nonstop, or cannot keep the basin from rising.

- Pump cycles constantly (oversized, short-cycling, or float issue).
- Pump runs nonstop (float stuck open).
- Pump runs but basin keeps rising (undersized for inflow).

Quick guide and key details
What changes price and scope
- Whether parts (check valve, float, battery) need replacement.
- Whether the discharge needs work.
- Whether the pump itself is failing and is replaced on the same visit.
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.

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.
Repair the pump you have, or know when to replace it
Most sump service calls split two ways: a pump that runs but doesn't move water (clogged impeller, stuck or failed check valve, an air-locked discharge) and a pump that won't start at all (seized float, tripped breaker, burned-out motor). We diagnose which it is before quoting parts, and we'll tell you honestly when a 7-to-10-year-old pump is past economical repair versus a quick float or valve swap. If the pit itself is the problem — wrong basin size, no sealed lid, missing weep hole — we cover that under Sump Pump Basin Installation.
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).
- Discharge water returns to the pit (failed check valve).
- Backup battery dead, weak, or alarm not working.
What's included
- Instrumented diagnosis: measure motor amp draw against the nameplate rating, time a full pump-out cycle, and clock how fast the pit refills to confirm the pump keeps ahead of inflow
- Clean the pit and intake screen, free or replace a stuck float switch, and clear debris or iron sludge from the impeller
- Test and reseat or replace the check valve, clear the discharge line, and confirm the weep/relief hole is open so the pump can't air-lock
- Test any battery backup or water-powered backup, load-test the battery, and verify the high-water alarm actually sounds
- Confirm the discharge daylights well away from the foundation and isn't tied into the sanitary sewer (against Toronto bylaw)
- Replace worn pumps, switches, valves, or piping with the part sized to your pit and head height, then re-test the full cycle
- Written summary of what was found and done, plus our 25-year workmanship warranty on the repair
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.

Paul Milgram
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.”

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!!”
