I did my first 2 inspections this week on my own, the 2nd house which looked like a ready to move in perfect little house had some things that I question, maybe you guys can help me out. This is in Las Vegas…
Main water line going into the house does not have a back flow preventer. It also doesn’t look like there is a yard that would need a sprinkler system, it seems to be a community yard, so is not having a back flow preventer ok since there is no sprinkler system connected to it?
I went up in the attic and there is 1 furnace unit installed but I did not see any fresh air ventilation. It had cocoon insulation so I thought maybe they put the insulation over the vents, but when I looked outside again there are no attic vents or soffit vents, just some small tile vents which I am not sure what their purpose is (see pics)
