I have a 5 year old shower pump which wasn't turning off! It started to be an intermittent fault but ended up continuously running.
I had a look at it today, put it back together and it is for the moment OK though I've no idea why. However, I'm intrigued as to how the automatic switching works; there looked to be some sort of sensor adjacent to the outlets. It's a John Sidney (who seem to have disappeared; the support line number doesn't answer) Cascade Automatic 50 Twin.
If the problem returns, as I suspect it will, what are my options?
