I am remodeling my basement and installing a wet bar.
There is an existing drain pipe that comes down the wall from the upstair kitchen which I will tap into to use for the wet bar sink. The distance from my wet bar sink to the drain is about 10 feet. My question is what is the proper height the drain needs to be from the floor under the wet bar to properly hook up the sink to the drain. I will be using standard cabnets with counter top and a 7 1/2 inch sink basin. My next question is there a rule of thumb for how many inches per foot the pipe needs to drop or angle for proper drainage. Thanks Stan
