Hello. I am moving my sink and water lines from one wall of my Kitchen to a peninsula 12ft across the room. I have cut my concrete about 18in wide from the original wall location to the new peninsula location. The original location was vented through the roof. I plan on tapping the drain and hot and cold from that original location. I am running all three lines together through the trench I have dug. Do I need to have an incline/decline in my "extension" drain pipe as it goes back to the original? I will "T" it into the original and leave the existing roof vent. Will I need a Studor valve at the new sink location? Anything else I am missing? Thanks for the advise!
