What Toronto homeowners should know
A pump that runs during a quiet test may still fail under sustained inflow. Maintenance should include the basin, float travel, check valve, power supply, discharge line and backup equipment.
The exterior discharge should remain clear, terminate on an appropriate permeable area and avoid sending water back toward the foundation.
Battery capacity declines with age and use. Follow the manufacturer’s testing and replacement guidance and keep service dates with the home records.
