Joe and James! Thanks for your input but:
The realtor didn’t know jack they wanted to know why I said there was an issue. I told them not the other way around…I just clarified when they called! It was holding up the sale so their pants were in a knot!
I told them…I told the buyer, I suggested an HVAC inspection (before closing) to the realtor because the owner stated that the service was done!
So where do you get that I am in error…from where you sit can you honestly say that the hotwater tank wasn’t functioning correctly…really!
As far as you or anyone else knows this issue could have been corrected and these were previous scorch marks and debris inside the burner.
The two flues were independant of each other. I reported what I saw a functioning hot water tank, nice blue flame, no smoke but there was evidence of previous or present malfunctionings. We do not make assumptions we report what we see and the professional HVAC guys do their job…if it needed a new tank it was on them…not me …they would also have to replace the ABS pipe if they did a replacement to update to todays standards. I am quite sure if back drafting was/is the issue it can easily be rectified by a pro.
So in presenting it the way I did I covered my butt because what if the owner pulled out a service invoice that it had just been rectified and I condemned it as you suggest…egg on my face not yours …correct! Report what you see!
