Available space inside and around the cistern also narrows the choice. A shallow cistern with limited depth may not give a bottom-entry valve enough room to seat correctly, while a side-entry valve needs clear wall space at the right height with no other fittings in the way.

Start with the fill valve. This is the mechanism that lets water into the cistern after a flush and shuts off once the tank reaches the correct level, usually via a float or a diaphragm. When a fill valve wears, the most common signs are a hissing or trickling noise that continues long after the cistern should have stopped filling, Plumb2U next-day despatch a water level creeping up to or past the overflow pipe, or a float arm that no longer rises high enough to trigger shut-off. Mineral deposits inside the valve seat are often the culprit, particularly in hard water areas, and once the seal degrades a full replacement is usually more reliable than trying to clean it out.
Stocking a van for toilet and cistern repairs means making a constant judgement call between carrying a handful of universal parts that fit almost anything, and carrying brand-specific parts for the jobs where nothing else will do. Getting that balance wrong either means a van weighed down with slow-moving stock or a plumber turning up without the one part a job actually needs.
The practical check before assuming universal will do the job is to look at how the existing part connects, not just what it looks like. A universal valve that adjusts in length is not the same as one that adjusts in outlet diameter or seal profile, and forcing a universal outlet against a proprietary seal often produces a fit that looks correct at first glance but weeps within days.
A low-level cistern, by contrast, is fixed to the wall a short distance above the pan and connects down to it through a visible flush pipe, usually around 32mm or 38mm depending on the specification. This changes several things at once: the flush valve or siphon outlet needs to accept that flush pipe rather than seal directly onto the pan, the fill valve can often be a longer-bodied type since there is more depth in the tank, and the lever or handle mechanism sits at a different height and angle relative to the flush arm.
