The unobstructed vertical distance through the free atmosphere
between the lowest opening from any pipe or faucet supply water to
a tank, plumbing fixture, or other device and the overflow level rim
of the receptacle, and shall be at least double the diameter of the
supply pipe measured vertically above the flood level rim of the vessel,
but in no case less than one inch.
