Carson Dunlop's sketch (left) shows the proper locations for disposal of air conditioner or heat pump condensate. Watch out: in our OPINION and as we discuss in these articles, while a trap on a condensate drain line, usually provided quite close to the condensate collection pan itself, can reduce the chances of sewer gases backing up from a condensate drain that has been connected to the building DWV vent piping (not a procedure we recommend), a conventional P-trap in the condensate drain will not protect against all sewer gas backup possibilities. Air-conditioning condensate waste pipes shall connect indirectly to the drainage system through an airgap or airbreak to a properly trapped and vented receptors dry wells, leach pits, or the tailpiece of plumbing fixtures. Dov Ber Kahn, a home inspector in Rockland County, NY has contributed photographs of various building features. Not suitable for use with flexible ducting.
