Hey guys,
Im a DIYer and I'm remodeling my kitchen. The current sink is on an inner wall that has the bathroom on the other side of it, and the main drain runs right up through that wall. My intentions are to move the sink from that area about 12 feet to the other side of the kitchen. My questions are, 1) can I extend to the main that far as long as there is a downward slope to it?
2)Do I need to have a new venting put in.
Thanks in advance..
