Introduction
Regular inspection and testing of condensate pump float switches is essential for preventing water damage, maintaining HVAC system efficiency, and extending equipment lifespan. This comprehensive inspection checklist provides facility maintenance professionals with a structured approach to verify the proper operation of float switches in condensate pumps throughout commercial and institutional buildings.
Float switches are critical control components that detect rising water levels and activate condensate pumps to prevent overflow. A malfunctioning float switch can lead to water damage, mold growth, equipment damage, and system downtime. Following this inspection checklist helps identify potential issues before they cause property damage, ensures proper drainage of condensate water, and maintains regulatory compliance with building safety standards.
Equipment Information
Pro Tips for Effective Float Switch Inspection
- Listen for Activation: A properly functioning float switch often makes an audible click when activated. Listen carefully during manual testing to confirm switch engagement.
- Test Secondary Switches: Many condensate systems have both primary and secondary (high-level alarm) float switches. Always test both to ensure redundant protection.
- Check Proper Orientation: Float switches must be installed at the correct angle to function properly. Verify installation matches manufacturer specifications.
- Document Activation Points: Record the water level at which switches activate and deactivate to track changes over time that might indicate impending failure.

Detailed Testing Procedures
Follow these structured procedures to ensure thorough testing of condensate pump float switches. Adapt these steps to your specific equipment configuration and facility requirements.
Manual Activation Test
- Ensure power is connected to the condensate pump system
- Slowly add clean water to the condensate reservoir
- Observe water level at which float switch activates pump
- Verify pump starts and continues running
- Allow pump to remove water and verify switch deactivation
- Measure and record activation/deactivation water levels
Electrical Continuity Test
- Disconnect power and isolate float switch circuit
- Set multimeter to continuity or resistance mode
- Connect probes to float switch terminals
- Manually manipulate float to closed position and verify continuity
- Move float to open position and verify no continuity
- Repeat several times to check for intermittent issues
Secondary Switch & Alarm Test
- Identify secondary (high-level) float switch
- Fill reservoir past primary float switch activation point
- Continue adding water to reach secondary switch level
- Verify alarm activation or notification system triggering
- Check building automation system for correct alarm reception
- Drain water and confirm alarm resets appropriately
Mechanical Inspection Protocol
- Remove float switch assembly if accessible
- Inspect for mineral buildup, debris, or damage
- Check float buoyancy by placing in water container
- Clean float and pivot mechanisms with approved cleaner
- Verify proper orientation during reinstallation
- Secure all mounting hardware and electrical connections

Maintenance Guidelines
These guidelines outline recommended maintenance tasks to complement your inspections. Following these schedules helps prevent condensate overflow incidents and extends the service life of your float switch and pump system.
Monthly Maintenance
- Visual inspection of float switch and basin
- Verify float moves freely with no binding
- Check for visible debris or contamination
- Add water to test basic pump activation
- Check for any signs of previous overflow
Quarterly Maintenance
- Clean condensate basin and float switch
- Check and clean condensate drain lines
- Test secondary safety switch and alarms
- Verify proper switch activation levels
- Inspect all electrical connections
Annual Maintenance
- Complete electrical testing of switch circuits
- Remove and thoroughly clean float mechanism
- Disinfect condensate basin and drain lines
- Check for wear and potential replacement needs
- Test integration with building automation system
- Update maintenance records and documentation
Biennial Recommendations
- Replace float switch if showing signs of wear
- Consider proactive replacement of switches > 5 years old
- Evaluate system capacity vs. current condensate loads
- Update alarm notification protocols if needed
- Consider upgrading to newer technology if applicable
