Toilet seat hinges look like one of the simplest parts on the whole cistern-and-pan setup, right up until the wrong replacement arrives and will not line up with the holes already drilled into the pan. Two fixing systems dominate the UK market, top-fix and bottom-fix, and they are not interchangeable without redrilling the pan, which nobody wants to do.

Before placing an order, it pays to note three things on site: whether the cistern sits flush to the pan or is wall-mounted above it, the fill valve's body length if there is a tight fit inside the tank, and whether the existing lever operates through the lid or via an external arm. Plumb2U carries fill valves, flush valves and levers suited to both close-coupled and low-level cisterns, stocked at trade prices for plumbers who need to get the right part on the first order rather than the second. Trade supplies despatch from Plumb2U's Epsom base to plumbers across the UK, and Plumb2U remains a straightforward call when the cistern type is not obvious from the pan alone.
Cable-actuated systems use a flexible cable in place of the rigid spindle, which allows the button to be positioned somewhere other than directly above the flush valve, useful on concealed cisterns and certain close-coupled designs where the lid mechanism does not line up with the valve beneath. The cable itself can stretch, kink or seize inside its outer sheath over time, and a button that has become stiff, or one that no longer springs back after use, usually points to the cable rather than the flush valve itself.
Two cisterns can sit on near-identical pans and still take completely different spare parts, and the reason comes down to how the cistern connects to the toilet below it. Close-coupled and low-level designs are the two most common configurations found on UK jobs, and confusing the two when ordering spares is one of the easier mistakes to make on a busy round.
