About this detail

This HVAC condensate drain trap assembly connects to an equipment drain pan using a union fitting and features cleanouts, vent tees, and an approved air gap above a local floor drain or sink. The trap drop dimensions are determined by the fan inlet pressure plus one inch, with intermediate legs sized according to half that height plus one inch. A removable plug cap is installed at the top of the vent tee, and an optional removable drain plug is provided for exterior installations. A companion sizing schedule correlates equipment capacities from zero to two hundred fifty tons of refrigeration with minimum condensate pipe diameters ranging from one inch to two inches. The chart is based on a one-eighth inch per foot slope with the pipe running three-quarters full of liquid, subject to local authority having jurisdiction approval.
