A valve plug onto its seat, a lever into its rest position, a plunger upwards. As long as they hold their force, nobody notices they are there.\u003c\/p\u003e\n\u003cp\u003eWhen a spring weakens, it never shows up as a spring problem, but as something else: a valve no longer closes cleanly, a lever no longer returns on its own, something drips somewhere.
