Good Morning and Thank you before hand.
My Kitchen sink drainage is a nightmare sometime and the smells are unbearable at others, so I need to redesign the way it was originally built. I have read the back pressure with the outside could be my issue as during parts of the year my sink drains with no issue! I have no issue anywhere other than the kitchen sink! I have checked for clogs and ran a sewer snake so that has been eliminated. Attached pictures of my drainage, help me redesign it? https://1drv.ms/i/s!AuahbSUVcTfni0FFVyDHyZNZxNNd
