QUESTIONS & ANSWERS:
Q1:   Does a toilet syphon have an in built internal overflow?
A1:   A syphon can be used as an internal overflow device, as long as the spillover point of the syphon is below any other external hole within the cistern body, normally the lever hole.

Q2:   How do I fit a toilet syphon to a close coupled toilet?
A2:   When fitting a syphon to a close coupled toilet, you need to ensure that the threaded tail of the syphon is trimmed back, to ensure that the syphon flush is not throttled back, giving you a poor flush. We recommend that the tail is trimmed back to 2-3mm from the back nut.

Q3:   How does the dual flush toilet syphon work?
A3:   The operation of the dual flush syphon, is to flush and release the lever to give you a full flush, and to flush and hold the lever down, to give you a reduced flush. By holding the lever down, this lifts up two washers (one small blue plastic and one small black rubber) that are located immediately below the metal C link. When these washers are lifted up, this allows air to enter the syphon and breaks the syphonic action, the water level in the cistern will drop to just below the top of the syphon body, therefore giving you a reduced flush

Q4:   How does the internal overflow on a toilet syphon work?
A4:   A syphon will internally overflow when the water level within the cistern reaches the spillover point. The water will trickle over the spillover point, and run down the downleg of the syphon, and into the toilet bowl.

Q5:   What are the two small white plugs for on the side of the syphon?
A5:   These are to reduce the flush volume of the syphon within the cistern. By removing the plugs you will reduce the volume of water supplied on the full flush. If no plugs are removed, the water in the cistern will drop to the bottom of the syphon body. If the bottom plug is removed, the water in the cistern will only drop to this level. If the top plug is removed, the water in the cistern will only drop to this level.
