What you see in the video is not an active plumbing leak, this leakage is occurring during an AAMA 511 test of the balcony door of the unit above the one where the video is taken. As a building envelope consultant at SKA Consulting Engineers, Inc. one is often retained to perform leak investigations, and many times the leaks take a while to show themselves, may be slow drips, and/or the leaks can be difficult to trace back to their source. Then there are these types of leaks… immediate waterfalls inside of a building.

If you are curious, this is a three-story, multi-family, wood framed construction residential building with OSB sheathing and building wrap. We are starting to see more and more of these type of issues with these types of structures and Eric Couch, PE believes we will see a lot more moving forward.
