[VAC] Re: water pump again

["Tom" <tmeeker@xxxxxxxxxxxxxxx>]

I think there is a built in air gap for lack of a better word, in the hot
water tank itself.  This built in air gap would allow for the expansion of
water when it gets hot.  Most likely this air gap at the top of an installed
tank would not have any elements in the area to worry about.  This is just
so much 'hot air' in that space. ;)
