: I would like to install another toilet in our lower level. We already have one in place with a sump pump basin, grinder pump liquifer and necessary ventalation. The location is very close to the basin, my question is weather I can place another toilet and have it drain into the same basin. Can I go above the ground level and have it flow in or should I cut the floor and try to tape into the side of the unit.
You can install another toilet to your existing basin. Here is a site that may help also. Dale's Plumbing Service Inc LMP
