code question

  1. Plumbing Pictures
    I recently had a plumbing inspection done and was told that the set up in the photo below was not approved. Can anyone explain why? The inspector was very brief and didn’t explain much. The dishwasher and the sink are both connected to this valve. Does each connection need its own shut off?
