I have a water issue in my finished basement where it's leaking through a specific wall and causing flooding. Initially, I thought it might be a foundation leak, so I opened up the wall from the inside. However, it turns out that the water spots on the foundation wall (made of cinder blocks) indicate that the leak originates from the top and moves downward, suggesting a potential water source on the main floor or nearby plumbing. I suspect the issue could be related to the roof, even though it's relatively new. I'm looking for suggestions on how to identify the source of this water leak. I've attached a picture for reference.

Yeah, I had a similar issue a while back. One thing that worked for me was flooding the outside ground, looking for leaks coming inside, just as you did. If nothing showed up, it might point to an issue higher up, perhaps from a roof leak or even condensation buildup causing issues in colder months. Keep an eye on how the weather affects it too!
It sounds frustrating! First off, make sure to check for any areas above the wall where water could be seeping in, like from a roof or any plumbing fixtures. You might want to use a thermal imaging camera or moisture meter, which a professional can help you with, to pinpoint the leaks without tearing up too much drywall. And if you're still uncertain, just keep investigating; sometimes, finding it can be a bit of a detective job!
