When I went around back I notice the window open and closed it. 25 degrees and snowing.
The sellers arrived with there agent and the opened the window back up. Heat was set at 80. (Good thing window was open)
When I arrived at the laundry/utility room and got a heavy wiff of CO I was glad the window was open as I was like a dog in a car grasping for air. The vent on the roof was rusted, the vent in the attic was transite and the section at the water heater was a joke.
I asked the sellers agent if the had the window open so they could live.
He said they had it opened due to them smoking. Never saw or smelled a cigarette the entire time I was there.
They called there HVAC guy and you can picture Sanford and Sons truck pulling up. I asked if this guy was repitable. He said he is the one that installed it. I said he should not be the one to fix it.
I still have a headache from the CO.
The entire vent pipe should be replaced in my humble opinion.
