Nonwater urinals shall
comply with ASME A112.19.3/CSA B45.4, ASME
A112.19.19, or CSA B45.5/IAPMO Z124. Nonwater urinals
shall be cleaned and maintained in accordance with
the manufacturer's instructions after installation. Where nonwater urinals are installed, they shall have a water distribution
line roughed-in to the urinal location at a height
not less than 5 6 inches (1422 mm) to allow for the installation
of an approved backflow prevention device in the
event of a retrofit. Such water distribution lines shall be
installed with shutoff valves located as close as possible
to the distributing main to prevent the creation of dead
ends. Where nonwater urinals are installed, not less than
one water supplied fixture rated at not less than 1 drainage
fixture unit (DFU) shall be installed upstream on the same
drain line to facilitate drain line flow and rinsing.
