Floor Drains
Floor drains are considered fixtures. The traps of floor
drains must have a permanent water seal fed from an approved source of water,
or an automatic priming device designed and installed for that purpose. This
permanent water supply has to retain the trap's seal and prevent evaporation
from drying out the trap. A dry trap lets sewer gases enter the building.
You can connect condensate drain waste from air conditioning
units to a floor drain, but it’s not enough to supply a permanent water seal. A
single drinking fountain waste can discharge to a floor drain if it's not in a
restroom. This is usually considered an adequate water supply to protect the
trap seal. The discharge from a garbage can washer can't discharge through a
trap serving any other device or fixture. Connect the waste pipe directly into
the greasy waste line, discharging through a grease interceptor. The receptacle
(floor drain) that receives the waste from the garbage can washer must have a
basket to collect solids 72 inch or larger In size. It's essential that the
basket be easily removable for cleaning. The hot and cold water connection must
be properly valved and have an approved vacuum fitting to prevent
cross-connection. Floor drains serving indirect waste pipes from food or drink
storage rooms or appliances can't be located in toilet rooms or in any
inaccessible or un-ventilated closet or store room. You can't install any type
of plumbing fixture in a morn containing air handling machinery. Special
fixtures such as baptisteries, ornamental pools, aquariums, ornamental
fountains, developing tanks or sinks and similar Cultures that have a waste and
water connection should have the water supply protected from back-siphonage
with an approved vacuum breaker.
