When to Replace Your Sump Pump: 6 Warning Signs for Durham Region Basements
Most sump pumps give warning before they fail. Learn the six signs, why pumps work harder in Durham Region clay soils, and why a battery backup matters.
Homes with high groundwater or heavy soils keep sump pumps busy. We install, replace and service pumps and battery backups so your basement stays dry when the storm hits.

A sump pump collects groundwater in a pit below the basement floor and pumps it away from the foundation before it can flood the basement. Hayes Plumbing installs new sump systems, replaces worn pumps, adds battery backups for power outages and services pumps for homes across Oshawa, Whitby, Ajax, Pickering, Courtice, Bowmanville and Clarington.
“We called Hayes Plumbing for a clogged main drain and they were here within 2 hours. Professional, clean, and got the job done right. Will definitely use again in Courtice.”
If you notice any of these, it is time to call a licensed plumber.

Sump pump work is priced by the pump, the pit and whether a battery backup is added, so we quote it after a site visit. Our spring sump pump maintenance guide notes that battery backup units cost about $400 to $800 installed and provide 6 to 12 hours of pumping on a full charge. Every installation and replacement comes with a free in-home estimate and a written quote before we start.

Common questions about sump pump service in Oshawa and Durham Region.
Most last about 7 to 10 years, less where the pump cycles constantly. If yours is in that range, plan the replacement before storm season rather than after a failure.
Power outages during storms are common and that is when the pump is needed most. A backup keeps pumping through an outage or a primary pump failure.
The Region of Durham's Basement Flooding Loan Program has offered owners whose basement flooded from a sanitary sewer backup an interest-free loan of up to $3,000 for an approved backwater valve and sump pump. Confirm the current terms with the Region before you book; we provide the invoice and inspection record it asks for.
Pour a bucket of water into the pit. The pump should start, clear the water within seconds and shut off. Test it in spring and fall.

Ontario’s spring thaw is coming, and sump pump maintenance in Durham Region should be at the top of every homeowner’s to-do list. March is the critical window — snow is melting, the ground is still partially frozen (so water runs toward your foundation instead of soaking in), and April’s heavy rains are just weeks away.
