Alerted to my wife, my belief that the shower was not switching on at all. I tried to phone the fella who fitted it, to ask if he could visit. Thankfully I got the answer phone, so left a message.
This morning my wife informed me that the shower is in fact working!!!!!
There is a pull socket off to one side, that was off, I was merely using the switch in the unit! Two switches!
EMBARRASSED! In fairness to me this pull switch is never off, but of course its clearly visible, and pre accident I would have investigated, and of course found it! Just never occurred to me to look for alternative explanations. Pre-accident I used to consider options/alternatives, now I default to 'worse case answer!' the fact I had, had the washing machine go, and the dog had to go for a costly vet visit, probably explained my 'doom & gloom', however, a have learnt a lesson, I will investigate/think in future! Oh yeah, repair man's just been, and it was a genuine fault, that I couldn't have sorted, and it cost me less than £30, result! .
