Well the plumber’s been and fixed everything again. We had a very strange tap (like a washing machine outlet) sticking out of our hot water pipe for some reason, which is what flew apart causing a cascade of water (not a resonance cascade thankfully) which soaked the bathroom and everyone in the vicinity in hot water.
Very plesant I’m sure you’ll agree.
Anyway, it’s all OK now, but the sooner we find a better place to live, the better…
