: Im planning on moving my kitchen sink to an adjacent : wall. What Id like to know is if there is a code/common : sense limit to moving a kitchen sink drain from the : vertical vent stack?: Thanks for any advice.The size of the pipe is important in determining the distance from the vent to the p-trap wier. 1-1/2 dirty arm length max 42 2 60 3 72 4 120The vent is to prevent syphoning of the p-trap. If the trap is sucked dry, sewer gas can enter the home.
