Drop food colouring in the cistern and check if the bowl water changes colour without flushing.

Is the relief valve dripping water in the gully trap?

Outside

In dry weather, do you see damp patches in the garden, lawn or driveway?

Listen carefully throughout your checks. Can you still hear running water when no taps, hoses or showers are going?
