After a cold shower this morning and the dish-washer not doing a great job recently, plumbing came to the fore. After some head-scratching (I’m doing a lot of that recently…), I happened to notice that our friendly plumber had turned the hot water system off at the control box! Mistake, our a cunning ploy for an expensive fix? Let’s presume the former. And the dishwasher has been behaving like the water softener has been failing, so I’ve spent some time on that and we’ll have to wait and see if it’s been fixed now. What’s the third thing to go wrong?
