Moving a bathroom sink - (with mating plumbing)
I have been reading the forum and have not found a situation quite like mine. We wish to relocate our bathroom sink drain to the right about 8 inches. The problem is the drain in the bathroom we are remodeling is mated up to the same drain pipe as from the bathroom sink on the opposite wall. I have seen where it is not legal to add an extension. Is it OK to add a new entry joint into the existing drain pipe? We would have to block off the joint from the remodeled side and only allow a single entry at the old location for the opposite sink, and add a new joint for the new sink. My husband is speaking of having to open the wall to the other bathroom (under the sink) to do all this but I really hate to tear into both bathrooms at the same time. Any suggestions?
