Siphonic Flushing
Siphonic Flushing System
A Siphonic Flushing System uses the combined power of gravity, water flow, and vacuum suction to remove waste efficiently and quietly.
How It Works
1. Flush Activation
When the flush button is pressed, water is released rapidly from the cistern into the toilet bowl through the rim holes and siphon jet.
2. Trapway Fills
The high-speed water quickly fills the specially designed S-shaped trapway. As the trapway becomes completely filled, the air inside is displaced.
3. Siphon Action Begins
Once the trapway is full, a powerful vacuum (siphon) effect is created. This suction force pulls waste and water smoothly through the drain, providing a strong and efficient flush.
4. Water Seal Restored
After flushing, fresh water refills the bowl and restores the water seal inside the trapway, helping prevent sewer gases and unpleasant odours from entering the bathroom.

Navilu Tip
For optimum siphonic flushing performance, ensure the correct trap type (P-Trap or S-Trap), proper outlet alignment, adequate water pressure, and professional installation. A well-installed siphonic toilet delivers maximum flushing efficiency with long-term reliability.
