See more on this at plumbers merchants.

A close-coupled cistern bolts directly onto the back of the pan with no visible pipework between the two. Because the outlet on the cistern base sits directly above the inlet on the pan, the flush valve or siphon needs a shorter outlet and often a rubber doughnut washer to seal the joint rather than a length of pipe. Fill valves on close-coupled units tend to be shorter in the body too, since there is less depth inside a compact tank.

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 bottom-entry fill valve, by contrast, www.plumb2u.com takes its supply vertically through the base of the cistern, in line with where a rising main or supply pipe comes straight up from the floor void or from beneath a low-level suite. This arrangement is generally quieter, since the incoming water enters below the surface of the tank rather than splashing in from the side, which is why many modern and replacement fill valves are built as bottom-entry as standard, often with a side-entry option built into the same body.

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.
