Arrived and found that the issue is with the wall hung lavatory sinks. They are back to back and share a common drain. Tried to snake with the auger, unsuccessfully. The western lav sink needs a new ptrap, 1 1/4 tailpiece extension and strainer as well. See photos Snaked sink via sink drain to clear clog and Installed new tailpiece, p trap and tubular extension piece. Ran water for several minutes and everything was draining properly
