Hi I wonder if any one can help me shed some light on an annoying problem? About a week ago I started hearing a constant dripping and trickling noise in the house, it is quite faint but loud enough to stop you from sleeping every night. I think it's coming from the water tank heater in the airing cupboard in our bedroom, it sounds like water dripping into a bucket and makes the noise all the time whether the heating is on or off. I here it more in the bedroom and at first it sounded like the noise was coming from above or the ceiling but I have checked the two tanks in the loft and can't hear anything dripping from them? I am totally clueless as to the cause as it's never done this before in the 6 years we have lived here. I am worried there's some kind of leak somewhere or something, does anyone have any ideas what it could be? And if it easy to repair? Thanks in advance
