5. Ensure that drip piping is supported to
relieve any stress on drip pipe connectors and
drain hub.
a. Drip piping
MUST
be supported no
more than 24 in. from drain hub tee.
6. Provide a suitable air break
between flood rim of the floor drain
and outlet of drip pipe. To meet code
on low base merchandisers, it may be
necessary to install a field-supplied
drip pipe reducer. An alternative is to
cut the last section of drip pipe at an
angle (where permissible by code).
7. Prevent drip pipes from freezing:
a. Do NOT install drip pipes in contact
with uninsulated suction lines. Suction lines
should be insulated with a nonabsorbent
insulation material.
b. Where drip pipes are located in dead air
spaces, such as between merchandisers or
between a merchandiser and a store wall,
provide means to prevent freezing.
