3. Setup and Installation
Follow these steps for proper installation of your FluidMaster 747 Fill Valve:
- Turn Off Water Supply: Locate the water shut-off valve for your toilet, usually near the base, and turn it clockwise until the water flow stops.
- Empty Cistern: Flush the toilet to drain the water from the cistern. Hold the flush handle down to ensure as much water as possible is removed.
- Remove Old Valve (if applicable): Disconnect the water supply line from the old fill valve. Unscrew the locknut from underneath the cistern that secures the old valve, then remove the old valve.
- Insert New Valve: Place the FluidMaster 747 fill valve into the hole at the bottom of the cistern. Ensure the shank is properly seated.
- Secure Valve: From underneath the cistern, thread the provided locknut onto the valve shank and tighten it by hand. Do not overtighten, as this can damage the cistern or valve.
- Connect Water Supply: Attach the water supply line to the brass connector (G 3/8" x 35 mm) at the base of the new fill valve. Tighten securely by hand, then use a wrench for a final quarter-turn, being careful not to overtighten.
- Adjust Height: The valve's height can be adjusted by twisting the upper section or using the water level adjusting screw (refer to product diagrams). Adjust the valve so that the critical level mark is above the overflow pipe.
- Restore Water Supply: Slowly turn the water shut-off valve counter-clockwise to restore water flow to the cistern. Check for any leaks around the connections.
- Adjust Water Level: Allow the cistern to fill. If the water level is too high or too low, fine-tune the float mechanism using the water level adjusting screw until the desired water level is achieved (typically about 1 inch below the top of the overflow pipe).

4. Operating Instructions
The FluidMaster 747 Floating Fill Valve operates automatically. Once installed and the water supply is turned on, the valve will sense the water level in the cistern. After each flush, as the water level drops, the float mechanism will activate the valve, allowing water to refill the cistern to the pre-set level. The valve will then shut off, maintaining the desired water volume for the next flush.
Ensure the water level is adjusted correctly during installation for optimal flushing performance and water conservation.
5. Maintenance
The FluidMaster 747 valve features a self-cleaning mechanism designed to minimize the need for frequent maintenance. However, periodic checks can help ensure its longevity and efficient operation:
- Regular Inspection: Periodically inspect the valve for any signs of wear, debris, or mineral buildup, especially in areas with hard water.
- Cleaning: If you notice slow filling or reduced performance, turn off the water supply and gently clean any visible debris from the valve's inlet screen or float mechanism.
- Avoid Harsh Cleaners: WARNING: Do not use in-tank, drop-in toilet bowl cleaners containing bleach or chlorine. Use of such products can result in damage to tank components and property, and may void the Fluidmaster warranty. Always use quality Fluidmaster parts when installing or repairing.
6. Troubleshooting
If you encounter issues with your FluidMaster 747 Fill Valve, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Cistern fills slowly or not at all | Low water pressure; clogged inlet screen; kinked supply line. | Check household water pressure. Turn off water, disconnect supply line, clean inlet screen. Straighten supply line. |
| Valve does not shut off / Water constantly runs | Water level set too high; float mechanism obstructed; faulty flush valve/flapper. | Adjust water level lower using the adjusting screw. Ensure float moves freely. Inspect and replace flush valve/flapper if necessary. |
| Leaks at connections | Loose connections; worn washers/gaskets. | Ensure all connections are hand-tightened, then a quarter-turn with a wrench. Replace any damaged washers or gaskets. |
