Exterior kitchen floor drain pipe

Detail of DTR09PH84--1001.01.173 showing drain pipe outlet. The "Schedule 40" PVC pipe, manufactured for underground applications, is set askew through wall, angled toward the creek [north], as were the jambs of the original drain tunnel, including the exterior jambs in the lower-right portion of the photo. The gray joint mortar has been modified to inhibit the erosion from the hydraulic conditions acting on this foundation masonry. The hydraulic mortar joints and the drain pipe will be covered by backfill to the restored [20th-century] grade. Laurence Ward, 2009
