Questions and answers
Look at the water level with the lid off. If it's up at the top of the overflow pipe and trickling over, the inlet isn't shutting off. If the level is below the overflow but water still runs into the pan, the outlet seal is the problem.
Usually grit in the valve's inlet screen or pilot hole, a worn valve, or an isolating tap that isn't fully open. Low pressure on high ground can add to it. We check each one before replacing anything.

If it's rusted, kinked, bulging or simply old, yes. It's a small extra while the water is off anyway, and it's the part most likely to fail next. We point it out and price it before replacing it.
At the water line marked on the cistern or valve, which sits below the top of the overflow. Set too high, it trickles away; set too low, the flush loses its strength.
