We want to move our washer and dryer downstairs there really isn't a drain right in the same room where the washer and dryer will be but there is a 3 inch pipe that drains the shower and the toliet(in the upstairs) right where the washer will be so the question is can we tap into that pipe for our drain and is there any codes we would be violating by doing so. We live in South Jordan, Utah 84095 Any help would be so appreciated. Thanks
