Newbie needs advice on hot water cylinders

Even so, surely the potable water in your system is seperate from the stored mass of water that is heated by the immersion?

Yes indeed, it is just that I'm used to the DHW itself being potable and it just slipped my mind that the mass in a conventional cylinder is DHW, but not potable. I'd probably prefer to avoid Boss White anyway, though.

Christian.

Pen pushers, innit.

If you can wash in it then it is potable.

It means 'drinkable'. Now you may be happy to drink hot water - others have more taste.

You can wash in the Ganges; I wouldn't recommend drinking it.

Potable water is any water you drink or wash with. Water is that stuff they use to wipe you down with.

You don't know much about this point do you?

So very wrong - potable means drinkable, nothing else.

Christian,

I did ring the local authority and the building inspector there informed me that changing a hot water cylinder does not fall with in the requirements to be inspected / notified, as, in my case it was / is classed as maintenance, as was / is the replacement of the controller and thermostats (room and HW).

With regards to the energy efficiency, he commented that unless buying second hand, all new tanks from reputable suppliers will be compliant with the new regulations.

Based on this information, and after a good days work the cylinder and new ballcock valve in the feed/expansion tank has been fitted and I have no major leaks, and just one small dribble from a compression joint which I'll sort out in the morning.

Not in water system terms it doesn't. Primary and secondary water. Secondary is potable, yet may be used to wash with, and you can put it in your mouth to brush your teeth and even swallow the odd bit here and there.

You can't do that with primary water.

I ken s**te when I smell it.

You better tell the OED then Dribble. They obviously know less about big words than you.

Don't you have access to a dictionary?

You're making things up again.

OED potable: drinkable. from latin potabilis, french potable = drink

It has a secondary meaning of quality - as in best quality of water.

You provide me with secondary water when I ask for potable and I'll sue.
