Always been curious why the white tap would have been installed. Temptation to turn it is enormous, even though I know what will come out.
Twiddling random taps can be problematic. Cycliste and I were staying in a hotel in Zermatt a while back, and there were some random taps on the wall of the ensuite bathroom which didn't seem to have any obvious purpose. I twiddled away with them merrily, and they seemed to have no effect on the shower, bath or sink. After a few minutes there was a banging at the door from an annoyed hotelier. It turns out they turned off the water to the ensuite in the room next door.
Sadly my Swiss German wasn't good enough to ask 'what the fuck are they doing in this room?'
Yeah, have one of those but not specific to the taps. As far as I can work out it will isolate the boiler as well, so should be all good. Not gonna investigate further on a Sunday afternoon.
Don't understand what the red hose is doing. It goes in the direction of the washing machine and dishwasher, but I'm pretty certain that the washing machine is only connected to the cold (blue hose at the top) and the boiler doesn't fire when the dishwasher is on. Bathroom hot is fed from the pipe going out the bottom of the picture.
