So at the
very end is it any
worster or is it
worstist? Should be of course in the end is it any worst. We all at times use unnecessary or meaning less words. Likely the drawing in of air through the teeth will soon be given a name, maybe it already has one? Be it tut tut, or anything else we have go use to inferring, rather than saying anything, leaving the receiver wondering what they have done wrong, and if they than do some thing, the other person will claim correctly of course they didn't say a word.
It is how things are all to often done. "You have put a socket that close to the sink?" is not actually saying it's wrong, but suggests it is. It does seem back in the 14th Edition there was a distance quoted, idea was sink should not be close enough to kettle so you could fill it without unplugging, however there were so many times including fitting of wall mounted water boilers where one needed a socket so the unit could be easy removed for cleaning, but whole idea was it was always plugged in at any other time.
I can't remember if gas or electric, but remember the glass bodied units that filled with a push on tube on the tap, and had a sounder which hummed or whistled when it boiled. Later we saw the urn, often screwed to the work surface so it could not be tilted to get one last cup, with a tap to fill it right above the lid.
I would still not drink from hot tap in a premises where I don't know how the water is heated, however I remember returning home from Algeria vie France, my wife picked me up with car and caravan and we drove home gradually. My question was can we drink water from the taps? as in Algeria unless it actually said potable on the tap, then you assumed you could not drink from it. My wife did not know, this is 1980's so question was do they sell bottled water in the shops, answer yes, so next question, do you think the French would buy bottled water if they could drink tap water, so since everything to drink in car was made with tap water, felt better not to drink it. All we had which we knew was safe was wine, Oh did my wife get drunk!
There water was likely better than ours, and we also now drink bottled water, but the reasoning like the Monty python witch burning sketch can get it wrong. We see it again and again "You can't have an earth electrode with a TN system" was a common statement, it was actually true, but only because it was not called an earth electrode, it was an "extraneous-conductive-part" same as can't use water pipe as an earth, however that does not mean a water pipe does not have a green/yellow wire attached as it is an extraneous-conductive-part.
Some things we have to say if you can, others we say if you can't, like light bulbs must state if not dimmable other wise they are with EU rules. So in the main with water we get
and unless we get that sign water from a tap is drinkable. If a boiler is likely to contaminant water, plumbers (workers of lead) would need to put up these signs in any public place. I looked for a standard sign "Do not drink hot water" or similar, but could not find one.
