Right, I'm not sure which one of the two pipes is nearer the "end of the line." I'm just assuming that the PVC valve is nearer to the well, but that may not be the case.

From the second photo, it looks like there might be a crack in the valve at the top. If you are going to replace the valve, i'd recommend using a brass full flow "ball" valve.
Might be worthwhile to insulate the exposed pipes under pressure.
good luck,chris

That was my assumption. But we all know what happens when you ASSuME. My plan was to find an all metal valve instead of PVC. I'd also be happy just putting a solid pipe in and skipping the valve, but since I don't really know what the purpose of any of it is or where it goes, I'll probably stick with a valve.
