How interesting you should refer to the heads as a Crapper. Capital C of course. Thomas Crapper was a very high class sanitary
engineer in London. He installed the
plumbing systems in many of the great
English stately homes. Near to where I live is a country mansion with cast iron manhole covers (sorry I should say person hole covers) enscribed "Thomas Crapper." Also were the lavatory pans so enscribed, hense the
toilet became know as the crapper. Give a wise person instruction and he or she will be yet wiser.
