My PVC MOJO's not as good as I'd like.
What am I looking at on the left of this 90? Is that 2nd HX condensate leaving from the blower compartment area and going down to a floor drain? Is that an air break just above it or a caped clean out? Where is that clear tube going up out of the pic? I see a second PVC tight to the cabent tapping near the bottem of the cabent. Wait a min, that would be the 2nd HX, no?
Sorry that pics as good a view as I have on this VHS tape.
I have a feeling this is a trick question. But I'll play along for the moment.
The clear tube looks like the same tubing used on condensate pumps. Since it's coming from higher than the pictured equipment I have to assume it's from another system entirely. Immediately to the right of that is a vent. Presumably they put it there to vent after the furnace's internal p-trap. And of course the PVC appears to go into the furnace to drain the condensate from heater operation.
Troubleshooting by closed circuit televsion are we?
T-shoot by CCTV, yes. It's the new thing, I thought you knew. LOL
