Follow these steps for proper installation of your FluidMaster 747 Fill Valve:
- Gbanyụọ ntinye mmiri: 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.
- Wepụ Valvụ Ochie (ọ bụrụ na ọdabara): 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.
- Valve echedoro: 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.
- Jikọọ Ọdụdọ Mmiri: 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.
- Gbanwee Ogologo: 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.
- Weghachite mbubata mmiri: Slowly turn the water shut-off valve counter-clockwise to restore water flow to the cistern. Check for any leaks around the connections.
- Gbanwee Ọkwa Mmiri: 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. Ntuziaka ọrụ
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.
