Curious. Just came to stick one of my boys in the shower and the Mercati bar shower was warm to the touch before any water had flowed through it.
In the room next door we had just run a bath.
Is this the sign of impending doom, or have I only just noticed something which is permanently the case?
I'm surprised that hot water is flowing in / near the bar shower to warm it up when its not in use.
Hot water has to get to your bar shower somehow; maybe it's plumbed very
close (eg through a wall) to the hot main that supplies your bath. If teh
connecting pipe is copper, heat will flow very well along it.

OK checked this morning and its all cold. Peculiar, never noticed it heati
ng up when the bath is being run before, and would be a slight concern over
legionella if this is happening every time that the bath is used (the show
er in question is less used in our house compared to the bath).
I'll keep an eye on it.

Pass, that's beyond my knowledge / understanding of plumbing! All I can say is that it was pleasantly warm to the touch and there was no water flowing either through the showerhead itself or (to my ears / knowledge) anywhere else.
We're on a combi boiler, so hot isn't present in the system at all times (if you get my gist), so it does stand to reason to a certain extent that it was heated up at the point at which the hot water was flowing around the house.
Should I have legionnella concerns?
Mine as well:-)
The thinking was along the lines... combi runs while you fill bath.
Plumbing probably shared with shower. pressure balancer operates passing
hot water to cold side.
A proper expert will be along shortly:-)
All the water is sourced from the mains so should remain clean even if
trapped in a warm pipe. I think!
