A sump pump is your basement's last line of defence against groundwater. When heavy rain or snowmelt raises the water table, water collects in the sump pit and the pump sends it outside before it reaches the floor. If the pump fails, a finished basement can flood in minutes. POM Plumbing installs, replaces, repairs and maintains sump pumps across Toronto and the GTA, and we help eligible homeowners claim the City of Toronto basement flooding subsidy.
We install new sump pits and pumps, replace failed and aging pumps the same day, add battery backups and alarms, and fix discharge lines that freeze or drain back toward the house. If your pump has stopped and water is rising, call (905) 625-8777.
New sump pits with liner, pump, check valve, discharge line and alarm, often combined with interior weeping tile.
Old, noisy or failed pumps replaced with a properly sized submersible pump, usually the same day.
Stuck floats, failed switches, burned-out motors, clogged intakes and broken check valves.
Backup pumps that keep working during power outages. See battery backup sump pumps.
Frozen, crushed or disconnected discharge lines rerouted at least 2 metres from the foundation.
Spring and fall checks of the pit, pump, float, alarm, check valve and backup.
Most Toronto homes are best served by a submersible pump. Here is how the main options compare.
| Pump type | Best for | Lifespan |
|---|---|---|
| Submersible (cast iron) | Finished basements, quiet and powerful | 7–10+ years |
| Submersible (thermoplastic) | Light to moderate water | 5–7 years |
| Pedestal | Narrow pits, easy servicing | 10+ years |
| Combination primary + backup | Homes with a history of flooding | 7–10 years |
| Battery backup pump | Power outages and pump failure | Battery 3–5 years |
| Water-powered backup | Backup without batteries | 10+ years |
Under the City of Toronto Basement Flooding Protection Subsidy Program, eligible homeowners can receive up to 80% of the invoiced cost for one sump pump, to a maximum of $2,250, plus up to $300 for a battery backup. The program offers up to $6,650 per property in total for eligible flood protection work completed on or after November 12, 2025. Eligibility rules apply, including the property type and disconnected downspouts. We provide the itemized invoice, photos and documents you need to apply.

Most replacements take 2 to 4 hours. A new pit with weeping tile connection takes one to two days.
They protect against different kinds of flooding. A sump pump removes groundwater that rises under and around the foundation. A backwater valve stops sewage from the city sewer flowing back into the basement during storms. Many Toronto homes need both, and the City subsidy covers both.

Your price depends on the pump, pit work, discharge routing and whether you add a backup. Typical Toronto ranges before tax and before any subsidy:
| Service | Typical cost |
|---|---|
| Sump pump repair | $200 – $600 |
| Sump pump replacement (existing pit) | $800 – $1,500 |
| New sump pit + pump + alarm | $2,500 – $4,500 |
| Battery backup added | $900 – $1,600 |
| Discharge line reroute | $250 – $700 |
| Spring or fall maintenance visit | $150 – $250 |
A sump pump that fails during a storm can flood a finished basement quickly. Our plumbers repair sump pumps the same day whenever possible, and replace them on the spot if the pump is at the end of its life.
Test your pump every spring and fall by pouring a bucket of water into the pit and watching it start and stop. Keep the pit lid sealed, clear the discharge outlet of ice and leaves, and replace backup batteries every 3 to 5 years. If your home has flooded before, consider a combination system and a plumbing inspection of your drains and backwater valve.

Yes. We provide the itemized invoice, photos and documents required by the City and explain the application steps.
Most sump pumps last 7 to 10 years with maintenance. Thermoplastic pumps may last 5 to 7 years, and backup batteries need replacement every 3 to 5 years.
In most cases, yes. We carry common floats, check valves and replacement pumps, so most repairs and replacements are finished on the first visit.
A sump pump removes groundwater from the pit. A backwater valve stops sewage from backing up from the city sewer. Many homes need both.
A cast iron submersible pump is the best choice for most finished basements because it is quiet, durable and handles heavy water. A battery backup is strongly recommended.
Twice a year, before spring thaw and before the fall rain season.
A new pit or changes to drainage may require a permit. Replacing a pump in an existing pit usually does not. We advise you before work starts.
It may be undersized, have a stuck float, a failed check valve letting water fall back, or a high water table. We diagnose the cause and fix it.
No. In Toronto the discharge must go outside, at least 2 metres from the foundation, and not onto neighbouring properties.
