Test and maintain the sump pump
A sump pump may sit idle until it is urgently needed. Periodic testing, a clear pit and a working discharge reduce the chance of discovering a problem during a storm.
Recommended timingBefore spring runoff and major storms
What to do
- Read the pump and backup-system manuals and keep the pit covered, accessible and free of stored items.
- Before wet seasons, test operation using the manufacturer method—commonly by adding clean water until the float activates—without reaching into an energized pit.
- Confirm the float moves freely, the pump starts and stops, and water discharges outdoors to an approved location away from the foundation.
- Inspect visible power cords, check valves, piping and battery-backup indicators for damage, leakage or alarms; replace backup batteries on their own schedule.
- Have a plumber or pump professional clean, service or replace equipment when testing fails, the pit contains heavy sediment, or electrical or sewage-ejector components are involved.
Do not reach into an energized sump, use a damaged cord or perform electrical work in a wet area. Sewage ejector systems require different precautions and qualified service.
