Questions & Answers
Q: Does it have an internal overflow?
A: Yes, as long as the spillover point is below any external holes in the cistern (e.g., the lever hole).
Q: How do I fit this to a close-coupled toilet?
A: Ensure the threaded tail is trimmed back to 2-3mm from the back nut to prevent throttling the flush.
Q: How does the Duo Flush work?
A: Press and release the lever for a full flush. Press and hold the lever to break the syphonic action early for a reduced flush.
Q: What are the white plugs on the side for?
A: These reduce flush volume. Removing them stops the flush at higher levels in the cistern.
Q: What is the black washer for?
A: This is used if you wish to convert the unit from dual flush to a single flush operation.
