I have a new construction house that was built in a group of 4 by the same builders - same construction, same floorplan. We have noticed some small inconsistencies, but this week I noticed one with my water heater setup and the way the emergency discharge is installed: The problem is that I can't find any evidence that this actually goes anywhere. There is nothing going down into the crawl space and nothing on the exterior of the house. Both of my neighbors with the same floorplan have this: Is this an issue that needs to be addressed? There is also a separate run of pvc with uncapped ends that I'm unsure of their purpose: Thank you.
