Down feed distribution is: a. A water supply system that uses a pressurized tank, usually in the basement, to supply water under pressure to the floors above. b. A water supply system used in tall buildings in which water from the street main is pumped to a rooftop storage tank and distributed to the building under pressure from gravity. Pressure is determined largely by the height difference between the tank and the floor served. Significant weight on the roof may require additional structure. c. A water mechanical system used only for heating. Many of these systems are also radiant systems. Some systems circulate hot water or steam to warm the building

Which of the following would have the greatest impact on the size and configuration of an accessible restroom? A. a 5 ft clear circular turnaround space B. maneuvering space on the outside of the entry door to the room C. clear space at towel dispensers and full-height mirrors D. a minimum 36 in access route into and through the room
A. a 5 ft clear circular turnaround space Providing for a 5 ft turning circle requires the most space of the four choices listed. If the turning circle is provided, it is very likely that a 36 in access space and clear space at the towel dispensers will also be available. The maneuvering space on the outside of the entry door is irrelevant to the interior dimension of the restroom.
