Equipment Information
Pro Tips for Effective Handwashing Sink Inspection
- Inspect During Peak Hours: Consider scheduling some inspections during peak usage times to identify issues that may only appear under high demand conditions.
- Check Temperature Stability: Test hot water temperature not just for maximum temperature but also for stability over a 30-second period to ensure consistent performance.
- Verify ADA Compliance: Ensure sinks meet current accessibility standards, including proper height, knee clearance, and control accessibility.
- Document With Photos: Take dated photos of any issues or repairs for maintenance records and compliance documentation.

Detailed Inspection Procedures
Follow these structured procedures to ensure a thorough inspection of handwashing sink assemblies. Adapt these steps to your specific facility requirements and sink configurations.
Water Temperature Testing
- Use calibrated thermometer with probe
- Turn on hot water and let run for 30 seconds
- Place thermometer under stream and wait for reading to stabilize
- Verify temperature reaches minimum 100°F
- Confirm temperature does not exceed 120°F for safety
- Record temperature in inspection log
Drainage Evaluation
- Fill sink basin approximately halfway with water
- Release stopper/plug and time drainage
- Complete drainage should occur within 60 seconds
- Listen for gurgling or unusual sounds
- Check for water backing up in other fixtures
- Inspect P-trap for leaks during drainage
Sensor Function Testing
- Approach sensor at normal hand position
- Verify water activates within 1-2 seconds
- Hold hands in position for 15 seconds to verify continuous flow
- Remove hands and verify water stops within appropriate timeframe
- Test at different angles to verify sensor coverage area
- Check battery indicator or power connection if applicable
ADA Compliance Verification
- Measure sink height from floor to rim (34" max)
- Verify knee clearance (27" min height × 8" min depth)
- Test controls for operation with closed fist
- Confirm 5 lbs or less of force needed for operation
- Check reach range for accessories (48" max height)
- Verify all exposed pipes are insulated
Maintenance Guidelines
These guidelines outline recommended maintenance tasks to complement your regular inspections. Following these schedules helps prevent issues and ensures optimal performance of handwashing sink assemblies.
Daily Maintenance
- Clean sink basin, faucet, and surrounding surfaces
- Check and refill soap dispensers
- Restock paper towels or check hand dryer operation
- Empty trash receptacles
- Visual check for obvious leaks or issues
- Ensure handwashing instructions are visible (if required)
Weekly Maintenance
- Clean aerator screen to remove buildup
- Check water pressure and adjust if necessary
- Test sensor function (for automatic faucets)
- Sanitize sink basin and faucet handles
- Check and clean drain basket/strainer
- Inspect caulking around sink edges
Monthly Maintenance
- Check all mounting hardware and tighten if needed
- Inspect supply lines and connections for leaks
- Test shutoff valves for proper operation
- Check P-trap for leaks and proper assembly
- Verify water temperature is within safe range
- Replace batteries in sensor faucets (if battery-operated)
Quarterly Maintenance
- Disassemble and clean aerator thoroughly
- Descale faucet components if mineral buildup present
- Clean P-trap to remove buildup
- Check drain lines for proper flow
- Inspect for signs of water damage around sink area
- Verify compliance with current health regulations

Defects & Maintenance Notes
Troubleshooting Common Issues
| Issue | Possible Causes | Recommended Actions |
|---|---|---|
| Low water pressure | Clogged aerator, partially closed supply valve, supply line restriction | Clean/replace aerator, check and open supply valves, inspect supply lines |
| Leaking faucet | Worn washers/cartridge, loose connections, damaged O-rings | Replace washers/cartridge, tighten connections, replace O-rings |
| No hot water | Water heater issues, closed hot water valve, crossed supply lines | Check water heater, verify hot water valve is open, confirm proper supply line connections |
| Slow drain | Partial blockage, debris in P-trap, ventilation issues | Clear blockage, clean P-trap, check vent system |
| Sensor faucet not activating | Dead batteries, misaligned sensor, circuit issues, debris on sensor | Replace batteries, adjust sensor angle, check wiring, clean sensor face |
| Foul odor from sink | Dry P-trap, biofilm in drain, sewer gas intrusion | Pour water in trap, clean drain with disinfectant, check vent system |
| Water temperature fluctuations | Mixing valve issues, water heater problems, competing water usage | Adjust/replace mixing valve, check water heater, evaluate facility water demands |
