Sandy…Before you get to far into the laundry tub project, there are a couple of things that you will be needing…1.—a drain , 2—a water supply. The drain will have to be accessable if you plan to have gravity drainage. There is a way to accomplish what you want done by using a effluent pump if suitable drainage lines are not available in your basemend. First thig to do, is to determine what kind of system youll be using. Merry Christmas………Bud……… Suncoast Plumbing Inc………… Sunny Florida…..
