Drain Basin Services in Toronto & the GTA
Toronto & the GTA • Call 647-784-8448
A basin is the collection point — for a sump pump, a sewage ejector, an exterior catch basin, or a yard drain. Each one needs to be sized correctly, kept free of debris, and connected to a discharge that actually moves water away. Tornado Plumbing & Drains services and replaces drain basins across Toronto and the GTA, from interior sump pits to exterior catch basins choked with leaves and silt. Sometimes the basin turns out to be only part of the trouble. When that happens we take care of the outdoor plumbing system repair too, whether that means a catch-basin outlet or a yard-drain run, while we are already there.

When this service makes sense
Part of Drain & Sewer Services in Toronto & the GTA
Book this service when
Book this when a catch basin, yard drain, sump pit, or ejector basin holds standing water, is packed with silt, sits above or below grade, or gives off a sewer smell.
Common signs
- Standing water in an exterior catch basin or driveway pit days after the rain has stopped
- A sump or ejector pit packed with silt, gravel, or sludge so the float can't swing freely
- Catch basin grate sitting below grade so it ponds, or heaved above grade so it traps debris
- Sewer or sulfur smell rising from a yard drain or floor-drain basin that has dried out or clogged
If you're not sure, compare these too
- Sump Pump Installation - when the basin in question is a new or replacement sump pit
- Sewage Ejector Pump Repair - when the basin is an ejector pit and the pump is the problem
- Drain Cleaning - when the smell or backup is at a floor drain rather than a basin

Quick guide and key details
What changes price and scope
- Basin type: sump pit, ejector basin, catch basin, or yard drain.
- How much debris or water has to come out.
- Whether components or the basin itself need replacement.
How a professional visit usually unfolds
1. Inspect basin
Open lid or grate and assess condition. Plan cleaning, repair, or replacement.
2. Clean / pump out
Remove debris, sediment, or accumulated water. Restores function.
3. Component check
Test pumps, floats, check valves, and discharge lines. Catches the next failure.
4. Repair or replace
Fix what is fixable; replace what is past its life. Keeps the basin reliable.
5. Outlet test
Confirm the discharge actually moves water away. A clean basin with a blocked outlet is still a problem.

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 basins fail when nobody's watching them
A basin only works if its inlet, the basin itself, and the discharge line are all clear at the same time, and that rarely happens on its own. Exterior catch basins fill with leaf litter, road grit, and the silt that washes off driveways until the sump goes solid; interior pits collect sediment that fouls the float and shortens the pump's life. We clean the basin to the floor, check the grade and the outlet, and tell you whether the unit needs a sump pump repair or just a clear-out.
Signs your basin needs attention
- Standing water in an exterior catch basin or driveway pit days after the rain has stopped
- A sump or ejector pit packed with silt, gravel, or sludge so the float can't swing freely
- Catch basin grate sitting below grade so it ponds, or heaved above grade so it traps debris
- Sewer or sulfur smell rising from a yard drain or floor-drain basin that has dried out or clogged
- A basin that overflows during heavy GTA storms because the outlet line is rooted or collapsed
- Cracked, sunken, or crumbling concrete basin walls letting soil and roots wash into the pit
- An ejector basin lid that doesn't seal, leaking odor and gases into the basement
What's included
- On-site assessment of the basin type, depth, inlet, and where the discharge actually goes
- Pump-out and full removal of silt, leaves, gravel, and sludge down to the basin floor
- Inspection of the outlet line and grate, with a camera scope offered if the outlet is suspect
- Float, check valve, and seal check on sump and ejector basins, plus a re-test under water
- Replacement of cracked or undersized basins and resealing of ejector lids where needed
- Debris hauled away, the work area left clean, and findings explained in plain language
- A written 25-year workmanship warranty on any basin we install or replace
Basin types we service
| Type | Purpose | Common issue |
|---|---|---|
| Sump pit | Collects groundwater for the sump pump | Pit too small, debris in pit, failed pump. |
| Sewage ejector basin | Collects wastewater from below-grade fixtures | Pump failure, vent issue, basin seal leak. |
| Catch basin (exterior) | Catches surface water at low points | Filled with leaves, silt, or debris; broken grate. |
| Yard drain / area drain | Drains hardscape or low points outside | Clogged with debris, frozen, broken outlet. |
Basin service cost
Pricing depends on the basin type, how much debris or water needs to come out, whether components need replacement, and whether basin replacement is involved. A residential sump pit clean stays in the lower range. Catch basin replacement, sewage ejector basin replacement, or new basin installation costs more.
What to share when you call
- Which basin type and where it is on the property.
- Symptom (overflow, slow drainage, smell, pump failure).
- How long since the basin was last serviced.
- Whether the discharge line is suspected.
- Photos of the basin and outlet if possible.
- Whether the basin floods during storms.
Toronto context
Drain basins, catch basins, area drains, and trench drains catch water at the source on Toronto properties — driveways with negative slope, walkout patios, basement window wells, and yard low spots. They only work if the discharge route is open. We service the basin, the trap, and the run to the storm or sump system as one system.
When this is not enough
Cleaning, repairing, or replacing a drain basin handles the basin itself. If your basement keeps overwhelming the basin during heavy rain — water rising past the basin, weeping-tile system saturated, or sump cycling constantly — the basin is not the bottleneck. The next step is a flood-prevention scope: backwater valve, sump pump system, or basement waterproofing system, depending on where the water enters.
What to confirm before approving basin work
- The discharge outlet should be tested, not assumed.
- Pumps, floats, and check valves should be inspected as part of the visit.
- Replacement should be quoted separately from cleaning.
Useful info on the call: basin type, location, symptom, and last service.
Frequently asked questions
How often should a catch basin be cleaned?
Annually at minimum, and after heavy leaf-fall or major storms. Many properties only realize the basin is full when the surface starts pooling.
What is the difference between a sump basin and a sewage ejector basin?
A sump basin handles groundwater. A sewage ejector basin handles wastewater from below-grade fixtures. They look similar but serve different systems and need different pumps.
Can a clogged outlet cause backup even if the basin is clean?
Yes. A clean basin with a blocked discharge still floods. Outlet testing is part of every honest service.
When does a basin need to be replaced?
When the wall has cracked, the seal has failed, or the basin is wrong size for the system. Decades-old residential sump pits sometimes need replacement during a flood-prevention upgrade.

Marco Szablewski
June 2019“We want to finish our basement but in the spring when the snow was melting we discovered several leaks in our basement. Serhiy came out to look at our basement and also offered a free camera drain inspection. He provided a very reasonable quote for the waterproofing and a sump pump and went over all our options. With the camera inspection he discovered roots growing through our drain and we called the city to get it cleaned out (luckily it was in the city portion of the drain line). Serhiy did not pressure us into anything and waited patiently (2 months) for us to get back to him - which I appreciate a lot. I am not a fan of pushy sales people. His crew just completed the job and we are very satisfied with the results. They did a fabulous job and left everything clean and tidy. Thanks again!”

August 2021“Peter from Tornado came well prepared for the job. We got power wash done. He did the work professionally and ensured through camera inspection that the line is fully cleaned and cleared after the wash was done. Would highly recommend Tornado to anyone needing a professional service at a reasonable price.”

November 2019“Called Sergiy at Tornado Plumbing and Draining because of a clogged toilet due to a small plastic container that was flushed down the drain by mistake. Sergiy resolved the issue, unclogged the drain, did the camera inspection and installed a clean out on the main drain for future maintenance. This is not the first time that we used his services, Sergiy and his team are skilled and experienced plumbers who are clean and mindful of their environment. We were very happy with their work, their work is reasonable priced and we would recommend them to anyone looking for exceptional service.”
