Sump pump, battery backup, and discharge test checklist

A functional sump-system checklist for basin and cover, primary pump, check valve, float travel, electrical supply, alarm, battery backup, charger, secondary pump, discharge piping, freeze and backflow risk, exterior termination, high-water simulation, maintenance, and owner handover.

6 items to check

Inspection progress0 of 6
0%

Basin, lid, pump size, intake, float, and service access are correct

Critical item

The pump should remain stable and operate without obstruction or unsafe open access.

Discharge pipe, check valve, supports, unions, and penetrations are complete

Critical item

Piping should resist movement, leakage, backflow, and vibration and allow service.

Electrical supply, receptacle, cord, alarm, and generator considerations are safe

Critical item

Power should follow adopted requirements and remain available under expected conditions.

Backup pump, battery, charger, capacity, and isolation are installed and tested

Critical item

Backup equipment should operate independently enough to address the stated outage or pump-failure scenario.

Exterior discharge avoids foundation return, erosion, freezing, and prohibited connections

Critical item

Water should reach an approved location without cycling back to the basin or damaging property.

High-water simulation, pump transition, alarm, leak check, maintenance, and records are complete

The owner should see the system operate under a realistic test and know maintenance intervals.

Use after new or replacement sump equipment is installed and before relying on it for flood protection. Avoid contact with contaminated water and energized equipment. Do not enter contaminated, structurally unsafe, energized, confined, or oxygen-deficient areas; do not open pressurized systems or handle sewage. Use qualified plumbing, electrical, remediation, environmental, and structural professionals where applicable.
