Leaks from Underneath

I, too, have experienced water dripping from the kettle while pouring. It appears that the kettle is leaking from the “works” underneath, not over the rim. The design of the kettle is such that there are parts that penetrate the walls of the water vessel within the kettle, and these penetrations rely on a tight fit to prevent leaking. I suspect that thermal expansion and contraction loosens these penetrations so they leak ever so slightly, but I can’t say for sure.
