I have a fairly new Mira Sport 9KW electric shower. It works well except that when either the washing machine or the dishwasher are in use downstairs it drips quite badly. There are no drips most of the time, so it's probably a water pressure issue. I have turned up the stopcock at the mains but now the shower pressure is too fierce (and the kitchen appliances switch off the water intake with quite a clunk!), although it cures the dripping issue. Is this a known problem and if so, is there a solution? I can live with it I suppose, but it's annoying.
