Where not otherwise indicated, tolerances on dimensions of 8 in. (200 mm) and larger shall be ±3%. Tolerances on dimen- sions less than 8 in. (200 mm) shall be ±5%. Minimum and maximum dimensions given herein (where stated as minimum and/or maximum) shall not be subjected to a tolerance beyond the limits given. Where dimensional ranges are specified and the words minimum and/or maximum do not appear, the upper and lower ranges shall notbe considered criticaland the appropriate toler- ances shall apply. All mandatory dimensional require- ments shall be as referenced in the body of this document. 3.2 Water Closets 3.2.1 Outlet Configurations. Outlet configurations shall conform to the dimensions shown in 5 (a) Figure 1 for floor-mounted bottom-outlet water closets or (b) Figure 2 for rear-outlet and rear-spigot-outlet water closets 3.2.2 Nonstandard Outlet Configurations.

The mounting details ofwall- mounted water closet bowls shall conform to the dimen- sions shown in Fig. 3, sketches (a), (b), and (c), for siphonic type bowls, blowout type bowls, and two-bolt designs, respectively. All mounting bolt hole diameters for wall-mounted water closets shall be 7 ⁄ 8 in. (22 mm) minimum. Elongated bolt holes for accommodating older fixture supports shall also be permitted. 3.2.4 Roughing-in Details. Water closet outlets shall rough-in at 10, 12, or 14 in. (254, 305, or 356 mm), or as specified in the manufacturer’s installation instructions. See Figs. 4 and 5. 3.2.5 Toilet Seat Hole Details.

This requirement shall not be applied where proprietary seats are supplied by the manufacturer. 3.3 Trap Seal Depth The trap seal depth for water closet bowls and urinals shall not be less than 2 in. (50 mm) when determined in accordance with para. 8.2. 3.4 Water Surface Area A water closet bowl shall have a water surface area of 5 ? 4 in. (125 ? 100 mm) minimum, as measured on a flat and level surface. 3.5 Ball Pass Diameter The trapway of a water closet bowl shall pass a 1 1 ⁄ 2 in. (38 mm) minimum diameter solid ball.
3.6 Spud Sizes The standard sizes for spuds on fixtures shall be as follows: (a) 1 1 ⁄ 2 or 1 1 ⁄ 4 in. for water closet bowls operated by flushometer valves (b) 1 1 ⁄ 4 , 1 1 ⁄ 2 , or 2 in. for water closet bowls operated by wall-mounted flush tanks (c) 1 1 ⁄ 2 , 1 1 ⁄ 4 , or 3 ⁄ 4 in. for urinals operated by flusho- meter valves (d) 1 1 ⁄ 2 in. for clinic sinks operated by flushometer valves Other spud dimensions shall comply with the require- ments of ASME A112.19.5. Spuds for water closets shall be located as specified in Figs. 4 and 5. 3.7 Water Closet Bowl Heights The following bowl heights shall be as defined. 3.7.1 Adult Water Closet.
