I changed mine yesterday (actually about ten years ago). But the water supply pipework to the bath (and other long piping runs, including gas lines) remains the same as it was twenty years ago. The principle being the longer the run, the larger the diameter of the pipe needed to keep up the flow rate. Which is why we don't have a petrol pipe only the same diameter as the main jet.
Built like a gun...will it go bang?
