Package Contents
Verify that all components are present before proceeding with installation:
- 1 x HOgardenME ABS Dual Flush Toilet Push Button (Quantity may vary based on purchase, e.g., 1, 2, 5, or 10 units)
Setup and Installation
This push button is designed for easy installation. Follow these steps carefully:
- Turn off Water Supply: Locate the water shut-off valve for your toilet and turn it off. Flush the toilet to empty the cistern.
- Remove Old Push Button: Unscrew and remove the existing toilet push button from the cistern lid.
- Verify Cistern Hole Size: Ensure your cistern lid has a standard hole diameter between 39-42mm. This button is specifically designed for this range.
- Install New Push Button: Insert the threaded shaft of the new HOgardenME push button into the hole on the cistern lid.
- Connect to Flush Valve: Screw the push button assembly directly into the flush valve mechanism. Ensure it is securely tightened but do not overtighten. This button is compatible with Siamp Optima 49 valves.
- Restore Water Supply: Turn the water supply back on and allow the cistern to fill.
- Test Flush: Test both the full flush and half flush functions to ensure proper operation and no leaks.

Operating Instructions
The HOgardenME Dual Flush Toilet Push Button features two distinct flush options for water efficiency:
- Half Flush (Liquid Waste): Press the smaller, inner button for a reduced water flush, suitable for liquid waste.
- Full Flush (Solid Waste): Press the larger, outer button for a full water flush, suitable for solid waste.
Ensure the button returns to its original position after each flush.
Maintenance
- Cleaning: Clean the chrome surface of the push button with a soft, damp cloth and mild, non-abrasive cleaner. Avoid harsh chemicals that may damage the finish.
- Inspection: Periodically check the button for smooth operation. If it sticks or feels stiff, ensure no debris is obstructing its movement.
- Leak Check: Regularly inspect around the base of the button and the cistern for any signs of water leakage.
Troubleshooting
Button Not Flushing or Sticking
- Check Alignment: Ensure the push button is correctly aligned with the flush valve mechanism.
- Obstructions: Look for any foreign objects or debris that might be preventing the button from moving freely.
- Tightness: Verify the button is not overtightened, which can restrict movement. Loosen slightly if necessary.
Water Leaking from Button Base
- Tightness: Ensure the button is securely screwed into the flush valve.
- Seal Integrity: Check the rubber seal (if present) between the button and the cistern lid for damage or improper seating.
