5. Setup and Installation

Follow these general steps for installing the flush valve. Specific toilet models may require slight variations.

1. Prepare the Toilet: Turn off the water supply to the toilet at the isolation valve. Flush the toilet to empty the cistern. Use a sponge to remove any remaining water.
2. Remove Old Valve (if applicable): Disconnect the water supply line from the fill valve. Unscrew the retaining nut from the bottom of the old flush valve and fill valve. Carefully lift and remove the old components from the cistern.
3. Install New Flush Valve: Place the new Flomasta flush valve into the large opening at the bottom of the cistern. Ensure the rubber washer is correctly seated on the outside of the cistern, and tighten the retaining nut from underneath the cistern until snug. Do not overtighten.
4. Install New Fill Valve: Insert the new fill valve into the smaller opening at the bottom of the cistern. Secure it with its retaining nut and washer from underneath.
5. Connect Components: Connect the overflow tube from the fill valve to the flush valve (if applicable). Attach the connecting hose from the flush valve to the push-button mechanism.
6. Connect Water Supply: Reconnect the water supply line to the bottom of the fill valve.
7. Test for Leaks: Slowly turn the water supply back on. Allow the cistern to fill. Check all connections for leaks. If leaks are present, tighten connections slightly.
8. Adjust Water Level: Adjust the float on the fill valve to achieve the desired water level in the cistern, typically just below the overflow pipe.
9. Install Push Button: Install the push-button assembly into the toilet lid or cistern opening, ensuring it aligns with the flush valve mechanism.

6. Operating Instructions

The Flomasta 8SF74FJ flush valve operates with a simple push-button mechanism. Press the button firmly to activate the flush. The valve is designed for efficient water release and quick refill.

7. Maintenance

• Regular Cleaning: Periodically clean the cistern interior and valve components to prevent mineral buildup, which can affect performance. Use non-abrasive cleaners.
• Check for Leaks: Regularly inspect the connections for any signs of leaks. Address any leaks promptly to prevent water waste and potential damage.
• Inspect Components: Over time, rubber washers and seals may degrade. If you notice reduced performance or persistent leaks, inspect these components and replace them if necessary.

If problems persist after attempting these solutions, it may be necessary to consult a professional plumber.
