Part of the dryer venting has come off of the wall. It looks as if it was being held in place with duct tape, I'm not an expert in install, but I do sell appliances and I don't think that's exactly up to code. One of the dryers is still vented to the outside, but two shouldn't be used until their venting is fixed.
Good Afternoon,
We appreciate you for bringing this to our attention. The maintenance team is aware and will get this taken care of for you. Please let me know if there is anything else we can be of assistance with.
Thank you,
Keith R. Harden Jr.
