This picture was taken in a closet where the air hander was. You can see the bottom of the unit and the white pipe that runs over to the drain is the condensate. I wrote in the report and explained to the buyer that when this trap is dry in the winter, the opportunity exists for sewer gas to be sucked back into the home and dispersed via the HVAC system. The seller agreed to fix it and the HVAC tech says that there is no problem with it and it is common and to code. I explained again to the buyer my concerns and asked her to get this HVAC tech to write her a letter documenting that the system was safe, which I know will not happen.
Am i incorrect about what this picture represents?
Edit: This is the letter the HVAC guy wrote, I am scratching my head
To whom it Concerns,
On July 24th,2O11 I performed an HVAC inspection on a property located at xxx., Virginia
Beach, VA. The area of concern was due to a home inspection stipulating the HVAC condensate
drain being tied into the sewage line and possibility of sewage gases escaping into the house via the
HVAC system. Upon my inspection and the assistance of the home seller and a neighbor, the systems in
these townhomes were designed in all units in this manner. There was no evidence present to suggest
sewer gases have been escaping into the HVAC system for this townhouse. By all accounts the system is
safe for use and occupant.
