Sump Pump Maintenance Checklist
A maintenance checklist for sump pumps covering float switch testing, impeller inspection, discharge pipe checks, and alarm verification — for basement and sub-ground drainage protection.
What is a sump pump maintenance checklist?
A sump pump maintenance checklist is a structured list of the 11 preventive maintenance tasks — covering visual, functional, cleaning, safety and record-keeping checks — that keep a sump pump running safely and reliably. It groups routine checks by frequency, from daily inspections to annual servicing, so FM teams and building engineers can plan and evidence preventive maintenance.
Core sump pump checks
- Inspect the sump pit for debris, silt, or blockages
- Test float switch operation by raising the water level or manually activating
- Clean the sump pit and pump intake screen
- Test the high-level alarm
- Record test results and any maintenance performed
What is a sump pump?
A sump pump removes water that collects in a sump pit, typically in basements, lift pits, plant rooms, or below-ground areas. Sump pumps protect buildings from flooding caused by groundwater ingress, rainwater infiltration, or equipment condensate. They are usually submersible units with float switch controls and may include duty/standby arrangements with high-level alarms for critical applications.
This checklist is one of 25 in our plumbing and water system maintenance checklists, covering pressurisation units, booster sets, storage tanks, TMVs and water treatment — pressure, hygiene and legionella control.
Typical Sump pump maintenance checklist
A practical starting point for planned preventive maintenance. Always refer to the manufacturer's O&M manual and site-specific requirements.

Visual Checks
- Inspect the sump pit for debris, silt, or blockages
- Inspect the power supply cable and connections for damage
Functional Checks
- Test float switch operation by raising the water level or manually activating
- Verify the pump starts and stops at the correct water levels
- Check pump runs without unusual noise or vibration
- Verify the discharge pipe is clear and flowing to the correct drain
- Check the non-return valve on the discharge pipe operates correctly
- Test duty/standby changeover where applicable
Cleaning & Housekeeping
- Clean the sump pit and pump intake screen
Safety Checks
- Test the high-level alarm
Record Keeping
- Record test results and any maintenance performed
