Another case of wrong

[kweiss]

The secondary drain pan line does not go anywhere. The line out of the unit and the line out of the pan tie together, but don't tie into a line out. Overflow waiting to happen.

Primary line appears to go uphill as someone said in the first pic.

The secondary drain and the safety pan were tied together but that was just a minor problem. Not the main problem that I am looking for. The secondary drain did exit the exterior wall at the bottom of the brick veneer by the A/C unit and was draining at the time of inspection.

Here is the write up straight from my report.

A. The condensate drain for the furnace A-coil located in the attic the way that it is presently installed indicates that the primary drain has a restriction as water is discharging out of the secondary drain near the condensing unit. Recommend this primary line be checked for blockage. B. The primary A-coil condensate drain line is improperly connected to an air gapped P-trap within the attic. The furnace is not a high efficiency furnace and does not make condensate in the heat mode thus the p-trap becomes dry in the winter months allowing sewer gas to escape into the attic with the possibility of sewer gas entering the air stream of the furnace thru the drain line. Recommend the P-trap be capped off and the primary drain be connected to the secondary drain line below the platform of the furnace. I would also recommend a 24 volt safety switch be installed on the condensate outlet of the safety pan which in turn shuts the A/C unit off in the event of water in the safety pan. This type of safety switch is intended to prevent water damage to a finished ceiling.

Ahhhhhh 80% = low efficency furnace, nice one Charlie.

Ah, I see it now. They do it similiarly here, but have not seen one at the drain like that in the attic. Didn't get the right perspective on the first photo.

Yes I confused the issue on purpose by posting more than one pic and everyone could not see the trees for the forest.

I see these kinds of installs all the time and have had builders jump up and down about it being right. But its not; this home was constructed in 2000 and my client is the third owner and this home had been thru another inspection.
The client today was a mild meek sort of gent just followed me around and let me explain things that I thought were important. I tried very hard to get him to understand about this P-trap probally went overboard he just kept nodding his head.

After the inspec was over he stated he was a Mechanical Engineer and under stood exactly what I was telling him and just kind of smiled.

Good night all have got double inspections tomorrow will see if I can get some more good PIC'S

Great post, Charlie!

I am new to this forum but the guy that did that drain line is a moron and I am not even an inspector.
