Equipment Information
Pro Tips for Effective Flush Valve Inspection
- Turn Off Water Supply: Always turn off the water supply before inspecting internal components to prevent accidents and water damage.
- Use Proper Tools: Have the right tools on hand, including adjustable wrenches, screwdrivers, and manufacturer-specific repair kits.
- Check Water Pressure: Verify that water pressure is within the manufacturer's recommended range (typically 25-80 PSI) for optimal flush valve performance.
- Document Everything: Take photos of issues and keep detailed records of all inspections and repairs for future reference.

Detailed Inspection Procedures
Follow these structured procedures to ensure a thorough inspection of toilet flush valves. Adapt these steps to your specific valve models and facility requirements.
Diaphragm Inspection Procedure
- Turn off water supply at control stop
- Remove flushometer cap carefully
- Lift out the diaphragm assembly
- Inspect for tears, holes, or mineral buildup
- Check by-pass hole for blockages
- Reassemble carefully in correct orientation
Vacuum Breaker Assessment
- Inspect vacuum breaker for cracks or damage
- Check for proper seating in tailpiece
- Verify rubber seal condition and flexibility
- Ensure proper height above flood rim
- Test functionality during flush cycle
- Confirm no leakage around vacuum breaker
Water Flow Adjustment
- Locate adjustment screw on control stop
- Flush toilet and observe bowl clearance
- Use screwdriver to adjust flow clockwise (less) or counterclockwise (more)
- Test flush after each adjustment
- Aim for minimum water use with complete evacuation
- Document final settings for future reference
Handle Assembly Inspection
- Check handle for proper return after actuation
- Verify plunger movement is smooth and complete
- Inspect handle packing for leaks
- Tighten handle nut if loose
- Test ADA compliance (5 lbs or less actuation force)
- Lubricate moving parts if necessary
Maintenance Guidelines
These guidelines outline recommended maintenance tasks to complement your regular inspections. Following these schedules helps prevent equipment failures and extends the service life of toilet flush valves.
Monthly Maintenance
- Visual inspection for leaks and proper operation
- Clean external valve surfaces
- Check handle or button for proper operation
- Verify no running water after flush cycle
- Test sensor function (if applicable)
Quarterly Maintenance
- Check water pressure at valve
- Clean filter screen in control stop
- Inspect vacuum breaker function
- Check all connections for leaks
- Measure and adjust water consumption
Annual Maintenance
- Disassemble and clean internal components
- Replace diaphragm or piston assembly
- Replace seals and O-rings
- Check compliance with current regulations
- Descale internal components as needed
Five-Year Assessment
- Evaluate valve for replacement consideration
- Check for newer, more efficient models
- Review water usage history
- Assess compliance with current codes
- Consider upgrading to water-saving technology

Defects & Maintenance Notes
Troubleshooting Common Issues
| Issue | Possible Causes | Recommended Actions |
|---|---|---|
| Valve runs continuously | Damaged diaphragm, debris in by-pass, relief valve issue | Replace diaphragm kit, clean by-pass hole, inspect relief valve |
| Insufficient flush volume | Control stop partially closed, low water pressure, clogged passages | Adjust control stop, check supply pressure, clean internal passages |
| Short flush cycle | By-pass hole too large, damaged relief valve | Replace diaphragm assembly, check relief valve seating |
| Leaking around handle | Worn handle packing, loose packing nut | Replace handle packing, tighten packing nut |
| Double flushing | Improper vacuum breaker installation, fixture/valve mismatch | Adjust vacuum breaker, verify valve compatibility with fixture |
| Flush valve chatters | Unstable diaphragm, water pressure fluctuations | Stabilize water pressure, replace diaphragm assembly |
| Sensor not activating (automatic valves) | Low battery, sensor range issues, circuit problems | Replace batteries, adjust sensor range, check circuit connections |
