For more detail, see Plumb2U Epsom.
Plenty of cisterns still in service across the UK do not use a flush valve at all in the modern sense, relying instead on a siphon mechanism that has been the standard gravity-fed flushing method in British toilets for decades. Understanding how a siphon works, and how it differs from a flush valve, matters because the failure signs and the fix are not the same.

A flush handle or lever that has stopped working properly is one of the more straightforward toilet faults to diagnose, but plumbers still lose time on it when the replacement lever does not match the flush valve fitting already in the cistern. Before reaching for a new part, it is worth ruling out a simple adjustment first.
The flush valve tells a different story. If water is draining slowly from the cistern into the pan even when nobody has touched the button or handle, the flush valve seal or siphon washer has likely perished and is no longer sealing the outlet at the base of the tank. This shows up as a cistern that refills every few minutes with no obvious trigger, sometimes described by customers as topping itself up rather than running continuously. On older gravity-fed systems built around a siphon rather than a valve, a split diaphragm inside the siphon body produces the same symptom.
When sourcing a replacement, the button, spindle or cable and flush valve should be treated as a connected set rather than assumed to be interchangeable across brands, since fixing centres, spindle diameters and cable lengths vary between manufacturers. Plumb2U stocks dual-flush buttons, spindles, cables and the flush valves they operate, at trade prices, so a plumber can source the whole linkage in one order rather than guessing which single part will solve a button that has stopped working properly. Checking the range at a plumbers merchants like Plumb2U before a job avoids a returned part that almost fits.
