Condensate Drain Piping
Table 14.
Condensate Drain Piping Considerations
•
Condensate drain plumbing must comply with national, state, and
local codes.
•
Route condensate drain lines away from air handler so they do not
interfere with access panels.
•
Slope the drain lines downward a minimum of 1/4” per foot,
support per local codes.
•
Do not use reducing fittings in the condensate drain lines.
•
Do not connect the drain line to a closed drain system.
•
Do not use a torch or flame near the plastic drain pan coupling.
•
A P-trap is not required for proper drainage due to the positive
pressure of the air handler; however, it is recommended to
prevent efficiency loss of conditioned air.
