Bottom-fix hinges are the traditional arrangement, with a bolt passing down through the pan from above and a nut and washer tightened from underneath the rim. This means access is needed both above and below the pan to fit or remove the seat, which is straightforward on a floor-standing toilet but considerably more awkward on a wall-hung pan where the underside is harder to reach, or where a previous fitting has corroded the nut solid against the porcelain.

Before ordering, check where the existing supply pipe meets the cistern and measure the available depth if the tank is compact. Plumb2U stocks both side-entry and bottom-entry fill valves, including combination types that cover both configurations from one body, at trade prices for plumbers who need to match the part to the pipework rather than the other way round. Plumb2U's range, backed by next-day despatch on the common models, makes it straightforward to specify the correct entry position before the part goes in the van.
toilet replacement parts supplier 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.
On button-actuated cisterns with a rigid spindle, the button sits directly above a plastic or metal rod that passes through the cistern lid and connects to a lever arm on the flush valve below. Pressing the small button rotates or depresses the spindle partially, lifting the flush valve seal just enough for a short flush. Pressing the full button pushes the spindle further, lifting the valve completely so the cistern empties in one go. Wear at the point where the spindle meets the flush valve lever is the most common failure here, often showing up as a button that clicks but produces no flush, or a short flush that no longer fires at all while the full flush still works.
