This first video shows the steps I took while removing the existing plumbing lines from the kitchen sink and the bathtub drain which were clearly causing major backups and debris buildup. One never knows what will be encountered when opening up old pipes, ceilings and walls, however, this will give you a good idea if you want to tackle something like this or leave it to someone else. I have most of the video running at 500% speed (or 5x original) in an effort to minimize the drudgery of it all. http://www.5280handyman.com
