Some unexpected good news this week: our water hammer has disappeared.
It's been a problem ever since we moved in, and apart from the annoying noise I've always been worried that eventually it would shake loose one of the pipe joints and we'd get a leak.
The water board to the rescue. They've been replacing the mains all round the area, and this week they came back to join up the new mains to all of the houses. It took a day or two to notice what was missing: the annoying 'thunk' whenever a tap shuts off has gone!
