This drain is the northern continuation of tile and stone drain 7196, on the other side of tufo blocks 7197. This appears to be its original northern limit, where it drains into some kind of (at present incompletely excavated) vertical shaft, facilitated by a repurposed broken amphora that served as a kind of crude pipe. It appears to be related to a small structure consisting of travertine slabs and tile (7256), on which it partially was constructed, but the function of that feature is, at the moment, unclear. Its relationship with surrounding layers and cuts is, at the moment, uncertain, because of the extensive reuse and spoliation in this part of Room 4.
