A leaking toilet can have several possible causes. It could be due to a faulty outlet seal under the toilet base, a loose or damaged inlet valve, a cracked cistern, or a worn outlet valve. To identify and fix the issue:

  1. Inspect for visible leaks: Check around the base of the toilet, the tank, and the connections for any signs of water.
  2. Check the toilet components:
    • Outlet seal: If the leak is around the base, and appears only when flushed the outlet seal may need to be replaced.
    • Inlet or outlet valve: If the leak is inside the tank (continuous running water sound), the inlet valve or outlet valve might need adjustment or replacement.

Addressing a leaking toilet promptly not only prevents water wastage but also avoids potential damage to flooring and surrounding structures.
