Figure 1-1 The older styles of water closets were identified as (A) reverse trap, (B)
blowout, and (C) siphon jet, to name a few. Though still used in the industry, these
terms are no longer used in the standards. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3

piping connection through the back wall. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4
Figure 1-4 A wall hung water closet attaches to the back wall; the water closet does not
contact the floor.. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4
Figure 1-5 The standard rough-in dimension is 12 inches from the centerline of the
water closet outlet to the back wall. The floor flange must be permanently secured to
the building structure.. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4
Figure 1-6 The minimum size water closet compartment is 30 in.×60 in. Spacing is
required from the centerline of the water closet to a side wall or obstruction and
from the front lip of the water closet to any obstruction. . . . . . . . . . . . . . . . . . . . . . . 6
