5. Installation

Follow these steps for proper installation of the Roca AV0022400R float valve:

1. Turn off Water Supply: Locate the main water shut-off valve for your toilet or the entire household and turn it off.
2. Empty the Cistern: Flush the toilet to drain the water from the cistern. If necessary, use a sponge to remove any remaining water.
3. Remove Old Valve (if replacing): Disconnect the water supply line from the old float valve. Unscrew any retaining nuts or clips holding the old valve in place and carefully remove it from the cistern.
4. Position New Valve: Insert the new Roca AV0022400R float valve into the designated opening in the cistern, ensuring the side feed connection is correctly oriented. Refer to Figure 2 for visual guidance.
5. Secure and Connect: Secure the valve with any provided retaining nuts or washers, ensuring a snug fit. Connect the 12x17 lateral water supply line to the valve's inlet. Hand-tighten first, then use a wrench for a final quarter-turn, being careful not to overtighten.
6. Restore Water Supply: Slowly turn the main water supply back on. Check all connections for leaks.
7. Adjust Water Level: Allow the cistern to fill. If the water level is not at the desired height, adjust the float mechanism on the valve according to the manufacturer's instructions (usually by rotating a screw or sliding a clip on the float arm).

6. Operation

The float valve operates by sensing the water level within the cistern. When the toilet is flushed, the water level drops, causing the float to descend. This action opens the valve, allowing fresh water to flow into the cistern. As the cistern refills, the float rises with the water level. Once the preset water level is reached, the float mechanism closes the valve, stopping the water flow. This precise mechanism ensures a rapid, silent, and reliable refill cycle, maintaining the correct water volume for efficient flushing.

7. Maintenance

To ensure the longevity and optimal performance of your Roca AV0022400R float valve, periodic maintenance is recommended:

• Regular Inspection: Periodically inspect the float valve for any visible signs of wear, damage, or mineral deposits (limescale).
• Cleaning: If mineral buildup or debris is observed, turn off the water supply and carefully clean the valve components. Use a soft brush and a mild, non-abrasive cleaning solution suitable for plumbing fixtures.
• Float Movement: Ensure that the float moves freely along its arm and is not obstructed by any part of the cistern or other components.
• Seal Check: Inspect the valve's internal seal for wear or damage. A worn seal can lead to continuous water running.

8. Troubleshooting

If you encounter issues with your float valve, consider the following troubleshooting steps:

• Slow Filling:
  • Check the water supply pressure to your toilet.
  • Ensure the valve inlet is not obstructed by debris or mineral buildup. Turn off the water and inspect the inlet screen.
• Continuous Running Water:
  • Inspect the float for obstruction or damage. Ensure the float arm is correctly positioned and not catching on any part of the cistern.
  • Check if the valve seal is worn, dirty, or improperly seated, preventing a complete shut-off. Cleaning or replacing the seal may resolve the issue.
• No Filling:
  • Verify that the water supply to the toilet is turned on.
  • Check for a complete blockage at the valve inlet.
