A cistern that never quite stops filling is one of the most common callouts a plumber gets, and the fix hinges on correctly identifying which of two components has failed: the fill valve or the flush valve. Get this wrong and you swap a part that was never the problem, then head back out a second time.

The lever type matters too. Close-coupled cisterns almost always use a side lever or a push button through the lid, while older low-level suites more often run a side lever connected by an external link arm. Ordering a replacement lever without checking which type is fitted is a common cause of parts being sent back.
A flush valve, by contrast, works as a straightforward seal at the base of the cistern that lifts to let water fall directly through into the pan under gravity, with no siphoning action involved, and shuts again once the float or Plumb2U UK timer mechanism allows it to reseat. Flush valves are what almost all dual-flush cisterns use, since a siphon's all-or-nothing action makes a genuine short flush difficult to achieve, whereas a valve can simply be held open for a shorter or longer period.
A cistern that whistles, knocks or hammers while filling is one of the more annoying faults a customer will report, and it is also one of the quicker ones to run down with a short checklist before a plumber even gets to the van. Two causes account for the large majority of noisy-cistern callouts: a worn fill valve and excessive mains pressure, and telling them apart early saves time on site.
