Ive had a problem with water for a while now as you have no doubt gathered, but just recently its started to get quite lairy. In the Spring I visited Glastonbury, and of course our caravan shook and gurned when I turned on the taps. This was so pronounced that two connections shook loose spraying water across the kitchen. Mean while I have just returned from  a holiday in Scotland where yes, you've guessed it that caravan shook when I turned on the taps and was filled by an almighty groaning from the water pipes. Back at home on the farm the same phenomena is happening even more violently than normal. The fact this has happened in three locations from one end of the country to the other is not coincidence. Its growing more noisey, its becoming more violent, and it sounds like some things going to explode soon, in fact others are beginning to ask questions too. Fascinating if a little worrying.
