AESTHETICALLY OBJECTIONABLE FACILITYOne in which substances are present which, if introduced into the public water supply system, could be a nuisance to other water customers but would not adversely affect human health. Typical examples of such substances are good-grade dyes, hot water, stagnant water from fire lines in which no chemical additives are used, etc.
AIR GAPThe unobstructed vertical distance through the free atmosphere between the lowest opening from any pipe or faucet supplying water to a tank, plumbing fixture or other device and the floodwater level rim of said vessel. An approved air gap shall be at least double the diameter of the supply pipe, measured vertically above the top of the rim of the vessel, and in no case less than one inch.
