Why is it that at 11.30pm every night, my shower let's go of a few dribbles of water, when the shower has not been used in the previous few hours and not since the morning?? EVERY night this occurs, whilst i am lying in my bed ready to sleep.... Does something happen at this time of night? e.g. the water pressure goes down or something, when everyone has finished with cups of cocoa, baths, showers etc.??? It really unnerves me......!
possibly when you turn off the shower, a small amount of water is still present in the head. Gradually it accumulates until there's enough weight of water to force it down through the head. This would probably take approximately the same amount of time to achieve every day? I'm just guessing.
