Again, on new construction, you just want to grab the guy and say, "Get real! You can do better than this!"
This is what we saw coming around the back side of the house.
This is a guy who knows purple primer should be used on PVC tubing.
This is a guy who does not understand aesthetics.
I notice that the sump pump guy understands both of those things to the point where he did not make his installation so ugly. He didn't take the UPC stickers off, however. Why not?
When my clients asked me what could be done now about this ugly installation, I said either replace the tubing and don't use the purple primer, or that possibly it could be sanded off.
But the sanding might make it look just as ugly!
This furnace exhaust is also 3' from the opening of the window. My understanding is that it should not be within 48". There is no guarantee that this window will not be open when the furnace discharges its exhaust (full of Carbon Monoxide). I pointed that out on the pre-drywall inspection and the clients asked the County about it, but the County approved it on the final mechanical inspection, so what appears to be dumb to me is just fine. The builder skirts again.
In addition to this furnace discharge being so near to the window, it will be right beside any deck or patio built there as the rear door is beside the window.
The intake tubing, the one pointing downward, is 18" from the ground. That is "considered" acceptable here, but I bet would be considered too low in areas that get regular, deep snows. It is important that this intake not be blocked in anyway.
What can I say?
My recommendation: it's the little stuff! If the little details are taken care of, you can expect that the larger things have been taken care of too. When they are not, well, it can be hit or miss.
