escape from the tank into the bowl continuously.
Inspect the fillvalve. If the tank keeps refilling when nobody has flushed, the valve or another component may need attention.
Check the overflow tube. Water continually entering the overflow tube may indicate that the fill level or fill valve needs adjustment.
Consider a water-efficient toilet. If your toilet is old and uses more water than modern models, replacing it may provide long-term savings.
Use a proper dual-flush system where appropriate. A suitable dual-flush toilet can offer different flush volumes for different needs.
