Why Sump Pump Failure Is the #1 Cause of Basement Flooding in Canada
Over 60% of residential basement flooding claims in Canada involve an overwhelmed or malfunctioning sump pump. During intense atmospheric rivers or rapid spring snowmelts, a failed sump pump can allow 500+ gallons of groundwater into your basement in less than 2 hours.
Quarterly Sump Pump Inspection Checklist 1. **Float Switch Test:** Pour 5 gallons of water directly into the sump basin. Verify the float activates smoothly without catching on the basin wall and shuts off when water drops. 2. **Weep Hole & Check Valve:** Inspect the 3/16" relief hole between the pump and the check valve to prevent air lock. Ensure the check valve prevents backflow into the basin. 3. **Debris Removal:** Disconnect power and clean gravel, silt, and hair from the pump impeller screen. 4. **Discharge Line Thawing:** In Canadian winters, verify the exterior discharge outlet is clear of snowbanks and free of ice dams. 5. **Battery Backup Verification:** Test your secondary 12V AGM or lithium backup system by unplugging the main AC power. Ensure the secondary pump triggers under load.
If your sump pump is older than 7 years or has failed during a storm, contact **1-800-692-7119** immediately for emergency extraction and plumbing dispatch.
