This image shows a connection I haven't run into before. At the left, the grey line is the discharge hose from the washing machine. This line discharges into the top of the upright pipe (top not visible in picture) then through what appears to be a trap, then directly into the sewer line. My question is: would you consider this a possible cross-connection? I'm not sure if this is an anti-syphon device or not or if this means of discharge is ok. Any thoughts?
