        What is the minimum gradient for a kitchen sink drain to the main house drain downpipe? Thank you for considering this question. Tracy Maness

          Tracey…It can be almost dead level, but it cant be more than 5 in length on a 2 waste arm if you are going to have it inspected…if no inspection is going to be required, 8 will work very well. Merry Christmas and Happy New Year…Bud Suncoast Plumbing.. Sunny Florida..
