I guess when all the walls are open, I should run and tie in a new 2 inch vent line in the new wall 6 inches above the flood line and bring it down into the basement to be ready to use should I need it for the lower down Wye, if that is needed in the main stack? If I need to not use that cross for the new toilet, I can if necessary, after the remodel, remove the toilet and PVC bend there now and put a new flange and 3 inch line from it down to the new 3 inch wye and tie in the 2 inch vent line to it. I don't know if I will be able to test it.............. hey wait! I can buy the new toilet now and test it out before ripping the whole room apart to see how it works. only wasted money would be a wax ring for the test. DUH! If there is a problem, I should see it with a few flushes, and I will know which way to go. Terry, by the way, where can I see that video you mentioned in your post # 4 of page 1 of this thread?
