Plumbing Distribution
351
BASIC DESIGN
The plumbing subsystem will be organized to follow the general pattern of
service distribution to and within the service modules. The main risers will
be grouped in the service bay and all distribution to the service module will
be horizontal through the service zone. All plumbing to the functional
zone will be downfed form the service zone, with the exception of gravity
drains.
The service bay and service zone spaces designated for plumbing
distribution must be adequate for maximum design loads and unused
routes will be reserved as a right-of-way for future extensions of the
subsystem. (See Figure 350-1.)
Main vertical and horizontal distribution components are considered
permanent. Branch distribution components and service bay equipment
are considered adaptable.
